    The purpose of this study was to integrate the available data published to date on susuk or charm needles into a com- prehensive analysis of their clinical/radiological features. An electronic search was undertaken in September 2019. Eligibility criteria included publications having enough clinical and radiological to confirm a definite diagnosis. The initial literature search resulted in 48 publications. Ten publications were excluded for duplicates, and another 17 excluded after a screening of the abstract. Besides, the screening of the abstract shows that five publications were not meeting the inclusion criteria, resulting in a total of 14 publications of susuk that were included in the systematic review. Bias analysis was conducted according to Oxford Center for Evidence-Based Medicine. The resulting total of 78 cases from the selected publications were analysed, showing a wide age range with different distribution among gender and ethnicity. Three cases reported in the literature having symptoms related to susuk. Susuk can be seen as an incidental finding during a routine radiographic assessment, and clinicians should be able to differentiate it from other radiopaque foreign bodies. The practice is not limited to South East Asian population and can be seen in wide racial profiles.

    Introduction: The Gallbladder stone (GBS) disease is most commonly asymptomatic that may lead to several complications such as ascending cholangitis and obstructive jaundice. In this study the frequency of gallblad- der stones among patients referred for abdominal ultrasound at the University of Science and Technology hospital (USTH), Sana’a – Yemen, have been estimated during the period between January and June 2013. Methods: This study is a record-based and conducted at the radiology department in USTH, on cases underwent abdominal ultrasound during the period from January – June 2013. Information were collected from abdominal ultrasonography reports. Results: In this study 4935 patients’ records are included. Of them, 2541 were males and 2394 were females. The frequency of patients with GBS was 5.53%. Multiple stones were observed in 3.57% of patients and 4.34% patients had large stones with size  5 mm. Females had significantly higher frequency of GBS (8.0%: 191/2394) than males (3.2%: 82/2541) (P < 0.001). It was found that, no significant difference between males and females in harboring small stones (< 5mm) (P = 0.251). However, significantly higher frequency of large GBS ( 5 mm) was found among females compared to males (P < 0.001). The frequencies of GBS, small size of GBS and large size of GBS have significantly increased with increasing age (P < 0.001). Conclusion: In this study it was found that females had significantly higher frequency of GBS than males. No significant difference between males and females in harboring small stones. There was a significantly higher frequency of large GBS was found among females compared to males. The frequencies of GBS, small size of GBS and large size of GBS have significantly increased with increasing age.

    George, J., Teo, S.C., Adan, M.
    Malays Orthop J, 2008;2(1):33-37.
    MyJurnal
    Aim: This study was designed to evaluate the use of ultrasound in diagnosis of infection and tumour of long bones. Methodology: Patients referred from the orthopaedic unit with doubt regarding long bone clinical and/or radiological signs which could be tumour or infection were enrolled in this study. Analysis of ultrasound characteristics included presence of pericortical fluid over normal cortex well away from the primary lesion, wavy contour sign (fluid tracking in and out muscle planes), subperiosteal fluid and soft tissue mass displacing adjacent muscle planes. Results: Fourteen out of 15 patients with confirmed osteomyelitis were diagnosed by ultrasound examination. Ultrasound as a diagnostic tool has a sensitivity of 93% and specificity of 100%. The most accurate indicator was pericortical fluid noted up to several centimetres from the long bone abnormality seen on plain x-rays. Conclusion: Ultrasound is a safe, fast, cost-effective imaging modality that can play an important role in diagnosis of osteomyelitis as it then serves as a tool for ultrasound guided aspiration.

    Yusof MI, Azizan AF, Abdullah MS
    Malays Orthop J, 2018 Jul;12(2):1-6.
    PMID: 30112121 MyJurnal DOI: 10.5704/MOJ.1807.001
    Introduction: This study is to evaluate the reliability, sensitivity and specificity of nerve root sedimentation sign (NRS) in our populations. The NRS is a radiological sign to diagnose lumbar spinal stenosis (LSS). It is claimed to be reliable with high sensitivity and specificity. Materials and Methods: A total of 82 MRI images from 43 patients in Group A (LSS) and 39 patients in Group B (non LSS) were analysed and compared for the presence of the NRS sign. Two assessors were used to evaluate intra and inter-assessor reliability of this sign based on 56 (33 patients, Group A and 23 patients, Group B). The findings were statistically analysed using SPSS software. Results: There was a significant association between spinal claudication and leg numbness with LSS (p<0.001 and Kappa=0.857, p<0.001). The inter-assessor reliability was also good (Kappa of 0.786, p<0.001). Conclusion: The NRS sign has high sensitivity and specificity for diagnosing LSS. The sign also has good intra and inter-assessor reliability.

  6. Fulltext Radiology in general practice
    Balasundaram R
    Family Physician, 1993;5(3):35-45.
    A survey of laws and regulations governing the practice of radiology by general practitioners in Malaysis and ten other selected countries wascarried out. It showedvaryingdegrees oflegal restrictions on the use of x-ray machines in the countries studied. Most regulations reflected the concern of radiation protection forpatients andstaff. Only some countries provide training for non-medical persons in the use of x-ray machines. Radiology has an important role in primary care. Undergraduate and post-graduate education should ensure competence in basic radiological practice. KEYWORDS: X-ray, general practice, regulations.

  7. Fulltext Atypical Cavernous Sinus Thrombosis: A Diagnosis Challenge and Dilemma
    Matthew TJH, Hussein A
    Cureus, 2018 Dec 04;10(12):e3685.
    PMID: 30761237 DOI: 10.7759/cureus.3685
    Cavernous sinus thrombosis (CST) is an ocular emergency because of its devastating effect and it is prone to cause serious complications. Diagnosis of cavernous sinus thrombosis is a challenging task despite medical advancement. Efforts to promptly diagnose and initiate treatment require a high index of suspicion and a deep understanding of the disease. Unfortunately, patients suffering from CST may not always present with typical symptoms, thus making diagnosis all the more challenging. We would like to describe a 22-year-old man who presented with atypical symptoms and radiological presentations of CST. The patient was admitted and treated in our institution with full recovery demonstrated after the treatment.

  8. Fulltext Painful Lytic Lesions of the Foot: A Case Report
    Vaishya R, Vijay V, Ghogare P, Vaish A
    Malays Orthop J, 2015 Mar;9(1):35-37.
    PMID: 28435595 DOI: 10.5704/MOJ.1503.005
    The presence of lytic lesions in the bones of foot raises a number of diagnostic possibilities ranging from infection, inflammatory pathology to neoplastic conditions. Although the radiological picture is not pathognomonic of any pathology, clinical history and histopathological examination can help to clinch the diagnosis. We present a case of multiple lytic lesions of the foot and discuss possible differential diagnoses. The patient was diagnosed as a case of madura foot and the lesions responded to surgical debridement and anti-fungal treatment with a good functional outcome. Madura foot is an uncommon, chronic granulomatous fungal or bacterial infection with a predilection in people who walk barefoot. Although known for a specific geographical distribution, madura foot should be kept as a possible diagnosis in patients presenting with lytic lesions of the foot due to population emigration across the world.

  9. Acute right upper quadrant pain: Evaluation by ultrasound at the General Hospital, Kota Bharu
    Sathyamoorthy P
    Family Physician, 1992;4:20-22.
    A retrospective study of 100 patients with acute right upper quadrant pain was performed in order to indicate the diagnostic role of ultrasound including the diagnostic role of ultrasound including guided percutaneous procedures in the evaluation of such cases at the General Hospital Kota Bharu (GH, KB). In the majority of these patients the leading clinical consideration was acute cholecystitis. In all the patients the initial sonographic diagnoses were compared with the final diagnoses. In 35 patients (35%) biliary pathology was diagnosed. In this group the conographic correlation was good. In 65 patients (65%) the symptoms were due to non-biliary pathology. In this group ultrasound detected the actual site of pathology in 28%. Ultrasonography which can image multiple organs rapidly is a useful initial screening procedure in patients presenting with acute right upper quadrant pain because it can detect the actual size of pathology in about two-thirds of the cases.

  10. Consensus guidelines on the optimal management in interventional EUS procedures: results from the Asian EUS group RAND/UCLA expert panel
    Teoh AYB, Dhir V, Kida M, Yasuda I, Jin ZD, Seo DW, et al.
    Gut, 2018 Jul;67(7):1209-1228.
    PMID: 29463614 DOI: 10.1136/gutjnl-2017-314341
    OBJECTIVES: Interventional endoscopic ultrasonography (EUS) procedures are gaining popularity and the most commonly performed procedures include EUS-guided drainage of pancreatic pseudocyst, EUS-guided biliary drainage, EUS-guided pancreatic duct drainage and EUS-guided celiac plexus ablation. The aim of this paper is to formulate a set of practice guidelines addressing various aspects of the above procedures.

    METHODS: Formulation of the guidelines was based on the best scientific evidence available. The RAND/UCLA appropriateness methodology (RAM) was used. Panellists recruited comprised experts in surgery, interventional EUS, interventional radiology and oncology from 11 countries. Between June 2014 and October 2016, the panellists met in meetings to discuss and vote on the clinical scenarios for each of the interventional EUS procedures in question.

    RESULTS: A total of 15 statements on EUS-guided drainage of pancreatic pseudocyst, 15 statements on EUS-guided biliary drainage, 12 statements on EUS-guided pancreatic duct drainage and 14 statements on EUS-guided celiac plexus ablation were formulated. The statements addressed the indications for the procedures, technical aspects, pre- and post-procedural management, management of complications, and competency and training in the procedures. All statements except one were found to be appropriate. Randomised studies to address clinical questions in a number of aspects of the procedures are urgently required.

    CONCLUSIONS: The current guidelines on interventional EUS procedures are the first published by an endoscopic society. These guidelines provide an in-depth review of the current evidence and standardise the management of the procedures.

    PMID: 22135550 MyJurnal
    Massive haemoptysis is the most dreaded of all respiratory emergencies. Bronchial artery embolisation is known to be a safe and effective procedure in massive haemoptysis. Bronchial artery of anomalous origin presents a diagnostic challenge to interventional radiologists searching for the source of haemorrhage. Here, we report a case of massive haemoptysis secondary to a lung carcinoma with the bronchial artery originating directly from the right subclavian artery. This artery was not evident during the initial flush thoracic aortogram. The anomalous-origin bronchial artery was then embolised using 15% diluted glue with good results. An anomalous-origin bronchial artery should be suspected if the source of haemorrhage is not visualised in the normally expected bronchial artery location.

    Central venous catheter placement is indicated in patients requiring long-term therapy. With repeated venous catheterisations, conventional venous access sites can be exhausted. This case illustrates the expanding role of radiology in managing difficult venous access. We present a case of translumbar, transhepatic, and transcollateral placement of central catheter in a woman with a difficult venous access problem who required lifelong parenteral nutrition secondary to short bowel syndrome. This case highlights the technical aspects of interventional radiology in vascular access management.

  13. Fulltext Automatic medical X-ray image classification using annotation
    Zare MR, Mueen A, Seng WC
    J Digit Imaging, 2014 Feb;27(1):77-89.
    PMID: 24092327 DOI: 10.1007/s10278-013-9637-0
    The demand for automatically classification of medical X-ray images is rising faster than ever. In this paper, an approach is presented to gain high accuracy rate for those classes of medical database with high ratio of intraclass variability and interclass similarities. The classification framework was constructed via annotation using the following three techniques: annotation by binary classification, annotation by probabilistic latent semantic analysis, and annotation using top similar images. Next, final annotation was constructed by applying ranking similarity on annotated keywords made by each technique. The final annotation keywords were then divided into three levels according to the body region, specific bone structure in body region as well as imaging direction. Different weights were given to each level of the keywords; they are then used to calculate the weightage for each category of medical images based on their ground truth annotation. The weightage computed from the generated annotation of query image was compared with the weightage of each category of medical images, and then the query image would be assigned to the category with closest weightage to the query image. The average accuracy rate reported is 87.5 %.

    Standard X-ray images using conventional screen-film technique have a limited field of view that is insufficient to show the full bone structure of large hands on a single frame. To produce images containing the whole hand structure, digitized images from the X-ray films can be assembled using image stitching. This paper presents a new medical image stitching method that utilizes minimum average correlation energy filters to identify and merge pairs of hand X-ray medical images. The effectiveness of the proposed method is demonstrated in the experiments involving two databases which contain a total of 40 pairs of overlapping and non-overlapping hand images. The experimental results are compared with that of the normalized cross-correlation (NCC) method. It is found that the proposed method outperforms the NCC method in classifying and merging the overlapping and non-overlapping medical images. The efficacy of the proposed method is further indicated by its average execution time, which is about five times shorter than that of the other method.

    PMID: 16898312
    Malaysia's mammography QA practice was surveyed based on the Malaysian Ministry of Health and the American College of Radiology (ACR) requirements. Data on mammography unit, processor, image receptor, exposure factors, mean glandular dose (MGD), sensitometry, image quality and viewbox luminance were obtained. Mean developer temperature and cycle time were 34.1 +/- 1.8degreesC and 107.7 +/- 33.2 seconds. Mean base+fog level, speed index and contrast index were 0.20+/-0.01, 1.20+/-0.01 and 1.33+/-0.26 respectively. Eighty-six percent of the fifty centres passed the image quality test while 12.5% complied with ACR recommended viewbox luminance. Average MGD was 1.0+/-0.4 mGy. Malaysia is on the right track for QA but with room for total quality improvement.

    Willatt JM, Mason AC
    Eur Radiol, 2006 Feb;16(2):437-44.
    PMID: 15702337
    The purpose of our study was to compare various aspects of radiology training schemes in ten countries. A questionnaire was sent to senior residents in the UK, USA, Canada, Australia, New Zealand, Italy, Egypt, India, Malaysia and Greece. The questions concerned length of training, required pre-training experience, the organization of the training scheme, teaching, resources, stages at which residents can independently perform and report examinations, fellowships, and progression to jobs. A wide variety of training, ranging from highly scheduled programs with detailed aims and objectives, to self-learning occurs across the world. Examinations and assessments are also variable. There are lessons to be learned from varying practices; more exchanges of ideas should be encouraged. In view of the "internationalization" of radiology services and the variation in training styles an international qualification for quality assurance purposes may be desirable.

  18. ASSESSMENT ON THE INTERCHANGEABILITY OF PERSONAL EFFECTIVE DOSE ALGORITHMS IN FLUOROSCOPY-GUIDED INTERVENTIONS USING BLAND-ALTMAN ANALYSIS
    Bohari A, Hashim S, Ghoshal SK, Mohd Mustafa SN
    Radiat Prot Dosimetry, 2019 Dec 31;186(4):462-468.
    PMID: 31329977 DOI: 10.1093/rpd/ncz051
    Long exposure to radiation from fluoroscopy-guided interventions (FGIs) can be detrimental to both patients and radiologists. The effective doses received by the interventional radiology staff after performing 230 FGIs in a year were assessed by using double dosimetry and five various algorithms. The Shapiro-Wilk test revealed normally-distributed data (p < 0.01), while the significant correlation coefficients between the effective doses ranged between 0.88 and 1.00. As for the Bland-Altman analysis, both Niklason and Boetticher algorithms strongly supported the absence of statistical significance between the estimated effective doses. This portrays that the occupational doses received by the interventional radiology staff during FGIs fall within the acceptable limit regardless of the varied algorithms applied. In short, the Niklason and Boetticher algorithms appeared to be the more interchangeable ones for effective evaluation of doses. This is in view of their strong mutual correlations and excellent agreement.

  20. Eye lens dose of medical personnel involved in fluoroscopy and interventional procedures at a Malaysian Hospital
    Wong JHD, Anem LEA, Tan S, Tan SK, Ng KH
    Phys Med, 2019 Dec;68:47-51.
    PMID: 31739145 DOI: 10.1016/j.ejmp.2019.11.007
    OBJECTIVE: This study measured the radiation exposure of the eye lens of medical personnel performing fluoroscopy and interventional procedures at the Sarawak General Hospital in Kuching, Sarawak, Malaysia. This study was the first in Malaysia to utilise in vivo radiation measurement relatively near the eye lens.

    METHODS: 41 medical personnel performing 79 procedures were monitored for their eye lens exposure using the NanoDot™ optically-stimulated luminescence dosimeters (OSLD) taped to the outer canthus of their eyes. The air-kerma area product (KAP), fluoroscopy time (FT) and number of procedure runs were also recorded.

    RESULTS: KAP, FT and number of runs were strongly correlated. However, only weak to moderate correlations were observed between these parameters with the measured eye lens doses. The average median equivalent eye lens dose was 0.052 mSv (ranging from 0.0155 to 0.672 mSv). The eye lens doses of primary operators were found to be significantly higher than their assistants due to the closer proximity to the patient and X-ray tube. The left eye lens of the operators received the highest amount of radiation due to their habitual positioning towards the radiation source.

    CONCLUSION: KAP and FT were not useful in predicting the equivalent eye lens dose exposure in interventional radiological procedures. Direct in vivo measurements were needed to provide a better estimate of the eye lens doses received by medical personnel during these procedures. This study highlights the importance of using direct measurement, such as OSLDs, instead of just indirect factors to monitor dose in the eye lens in radiological procedures.
