    X-ray based radiological procedure statistics and trend in Malaysia for 1990-1994 is reported; this information allows comparisons to be made with the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) Report. Additionally it is essential information for health care planners and providers. Malaysia is categorised as a health care level II country based on the UNSCEAR definition. In 1994, the number of physicians, radiologists, x-ray units and x-ray examinations per 1000 population was 0.45, 0.005, 0.065 and 183 respectively. 3.6 million x-ray examinations were performed in 1994, with chest radiography being the commonest study (63%). Information on x-ray examinations, number of hospitals and x-ray units is reported for the Ministry of Health, private practice and teaching hospitals. Examination frequency increased in computed tomography (161%), cardiac procedures (190%), and mammography (240%); while a decrease in barium studies (-23%), cholecystography (-36%), and intravenous urography (-51%) was noted. There is a potential and need to expand and upgrade radiological services.

    Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts and granulomas in the hope to identify features that maybe suggestive of either diagnosis. The results showed that a regular (circular or semi-circular) radiographic outline is likely to be a periapical cyst while an irregular radiographic outline is not indicative of either a cyst or a granuloma. The association between the regular/irregular radiographic outline and the type of periapical lesion was found to be statistically significant (p less than 0.001). The associations of two other radiographic features and the type of periapical lesion were found to be just statistically significant (p less than 0.01). These features are the symmetry/asymmetry of the radiolucency in relation to the apex and the funnel-shaped/angular-shaped extension of the radiolucency. The widely accepted criteria that the possession of a radiopaque cortex surrounding the radiolucency can discriminate between a periapical cyst and granuloma cannot be statistically supported in this study.

    AIM: The study aims to determine the frequency of positioning errors, record the number of diagnostically inappropriate images, and assess the quality of panoramic radiographs.

    MATERIALS AND METHODS: In this study, a total of 2629 patients for whom orthopantomogram were selected out of 3900 new patients between August 2020 and June 2021. The positioning errors of the radiographs were evaluated and categorized into ten groups. The quality of the radiographs is further assessed as "Excellent," "Diagnostically Acceptable," and "Diagnostically Unacceptable."

    RESULTS: Out of the total radiographs, 32.8% had no errors, and 77.2% of the radiographs had one or more positioning errors. The radiographs were analyzed in detail, and the errors found in the panoramic radiographs were recorded. The most common positioning error observed in the radiograph was error 8, failure to place the tongue close to the palate.

    CONCLUSION: The results and evaluation inferred that attention to patient positioning and focusing on reducing diagnostically indecent images could improve the quality of panoramic radiographs. Proper instructions to the patient, patient preparation, appropriate positioning of the patient, and the technician's skill plays a vital role in reducing diagnostic errors in Panoramic Radiography.

    The radiographs of fifteen Malaysian patients with presenting ameloblastoma aged between 20-55 years (average 35 years) were studied for any peculiar local features. The most common features were cortical plate expansion (80%), corticated scalloped margin (67%), multiloculation (87%), and resorption of tooth roots (47%). The latter two features are constantly found in advanced tumour stage. As pain was not a frequent complaint, many Malaysian patients seek treatment only at a very late stage after the tumours have reached large dimensions. Although ameloblastomas may be diagnosed often through radiographs, it should not be relied upon solely.

    The main objective of this study is to illustrate the role of ductography in the management of nipple discharge. Thirty-six patients had ductography for the investigation of blood-stained or serous nipple discharge. The ductogram findings were reviewed. Ductography showed an intraductal lesion in 13 patients, duct ectasia in 16 and normal ducts in 7. Fourteen patients had surgery. Eight had preoperative ductography using a mixture of methylene blue and contrast media. Histology revealed 5 cases of duct papilloma, 2 cases of epithelial hyperplasia, 4 cases of fibrocystic change and 3 cases of duct ectasia. Twenty had follow-up without surgery and of these, the nipple discharge ceased in 11 patients. Two patients did not come for follow-up. Ductography has a significant role in the management of nipple discharge. Firstly, surgery might be averted in patients with normal ducts or duct ectasia on ductography. Secondly, intraductal methylene blue will demonstrate the abnormal ductal system to the surgeon and allow for a less radical surgery.

    This study is designed to compare and evaluate the diagnostic image quality of dental panoramic radiography between conventional and digital systems. Fifty-four panoramic images were collected and divided into three groups consisting of conventional, digital with and without post processing image. Each image was printed out and scored subjectively by two experienced dentists who were blinded to the exposure parameters and system protocols. The evaluation covers of anatomical coverage and structures, density and image contrast. The overall image quality score revealed that digital panoramic with post-processing scored the highest of 3.45±0.19, followed by digital panoramic system without post-processing and conventional panoramic system with corresponding scores of 3.33±0.33 and 2.06±0.40. In conclusion, images produced by digital panoramic system are better in diagnostic image quality than that from conventional panoramic system. Digital post-processing visualization can improve diagnostic quality significantly in terms of radiographic density and contrast.

    Tuberculosis (TB) remains a global health problem and is the second leading cause of death from a single infectious agent, behind the novel coronavirus disease of 2019. Children are amongst the most vulnerable groups affected by TB, and imaging manifestations are different in children when compared to adults. TB primarily involves the lungs and mediastinal lymph nodes. Clinical history, physical examination, laboratory examinations and various medical imaging tools are combined to establish the diagnosis. Even though chest radiography is the accepted initial radiological imaging modality for the evaluation of children with TB, this paper, the first of two parts, aims to discuss the advantages and limitations of the various medical imaging modalities and to provide recommendations on which is most appropriate for the initial diagnosis and assessment of possible complications of pulmonary TB in children. Practical, evidence-based imaging algorithms are also presented.

    Bisecting-angle-technique is a method used to improve patient comfort during periapical radiography. This technique is usually performed without X-ray beam aiming device and has been commonly associated with dental radiographic error. The use of external marker as a beam aiming device in bisecting-angle-technique is potentially effective to reduce the number of errors occurring during periapical radiography. In this study, 240 periapical radiographs were taken by undergraduate dental students. Periapical radiographs were taken using traditional method of bisecting-angle-technique (BAT), bisecting-angle-technique with the use of external marker (BAT-M) and the standard method in periapical radiography; paralleling technique (PT). All radiographic images were evaluated and errors were classified and tabled according to the type and number of errors. Chi-square test was used to compare the total number of radiographic errors made using these three techniques. One of the most common errors with BAT was cone cut error (13.8%). This error had been markedly reduced to 1.3% and 2.5% by implementation of BAT-M and PT, respectively. The total number of errors was also found to be significantly lesser for BAT-M compared to BAT, p< 0.05.

    Mental foramen is an opening of the mental canal onto the lateral surface of the mandible. In this pilot radiographical study, in Malay population the effects of ageing towards the location and visibility of the mental foramen were determined. Most of the mental foramina were found to be located inferior to the apex of the second premolar. Non-visibility of the foramen was greatly increased in patients aged 50 years and above (Pearson Chi-square; p = 0.00). This finding may provide a guide to dental surgeries in Malay patients of different age groups.

    Chest X-ray is valuable in the primary care setting in helping clinicians to confirm the underlying findings of the respiratory and cardiovascular systems. This view also includes the lower cervical vertebrae region which is helpful in elaborating the findings surrounding the neck. However, a single view of the film may sometimes cause confusion regarding the exact origin of the abnormal signs of the X-ray images. Thus, clinical correlation and application of 'rule of two' in X-ray imaging is definitely useful to clarify the findings and avoiding any misdiagnosis, medical errors and non-justifiable further investigations. Here we report a case of an 18-year-old female student with abnormal radiopaque neck mass seen from her chest the X-ray image. She was clinically well without any significant clinical findings. Surprisingly, the findings totally resolved after repeat the Xray at two different occasions within the same week. This strange abnormal finding was later confirmed to be her hair tier. She was saved from unnecessary investigations for tuberculosis and thyroid disorder by repeating the X-ray (rule of two occasions). Now you see, now you don't of X-ray findings is indeed illogical and technical error needs to be rule out.
