Fish is one of the major sources of protein among Malaysians. This has made incidents of fish bones lodged in the throat fairly common clinical problems. Plain radiograph, which is the first line of imaging in such cases, has been reported to have low sensitivity. Besides the location, the degree of radio-opacity of the bone is another important factor and is species dependent. This study was undertaken to determine the radio-opacity of bones from commonly consumed fish in Malaysia. A total of 15 types of fish were identified, six of them were opaque even when embedded and three were visualized in the simulated airway. In terms of radio-opacity, the commonly consumed fish in Malaysia possessed opaque bones and this fact can help doctors identify the location of the foreign body in the throat.

BACKGROUND: Brain ischaemia and infarction are the leading factors in morbidity and mortality of traumatic brain injury. This study aimed to determine the perfusion status of pericontusional hypodense areas in traumatic cerebral contusion
METHODS: Ten patients involved in motor vehicle accidents were enrolled in this study, and contusions were diagnosed from plain computed tomography scans of the brain. Subsequent computed tomography perfusion (CTP) was performed to analyse the perfusion of pericontusional hypodense areas, which were divided into 4 regions of interest (ROI).
RESULTS: Most ischaemic perfusion was found in ROI 6 (affecting 60% of patients), although the mean of the perfusion parameters were normal. A significant positive correlation was found between the perfusion status in the pericontusional area nearest to the skull vault (ROI 3) and its distance/thickness to the skull vault (r = 0.698, P = 0.025). Two adjacent pericontusional hypodense areas (ROI 4 and ROI 5) showed a significant positive correlation with each other (r = 0.667, P = 0.035) in terms of perfusion status. The presence of a hypodense pericontusional area is suggestive of oedema and perfusion disturbances.
CONCLUSION: CTP is a useful, fast, and appropriate method in evaluating perfusion of pericontusional hypodensity area that may help the treating physician to provide an appropriate treatment to the patient.
