The aim of this prospective study was to evaluate the diagnostic accuracy of multidetector computed tomography (MDCT) in detecting occult scaphoid fractures. ⋯ MDCT offers highly accurate results, especially concerning cortical involvement, and is a useful alternative in facilities lacking MRI.

A 76-year-old woman was found in cardiopulmonary arrest with her head submerged in water in a bathtub. Despite cardiopulmonary resuscitation (CPR) for over 1 h by professional emergency technicians and medical doctors, the patient died. ⋯ It was speculated that intravascular gas was generated and spread to multiple organs during CPR procedures via the alimentary tract and lungs, which had been damaged by ischemia after cardiopulmonary arrest. Prolonged CPR procedures may involve the risk of additional organ damage and systemic air emboli.

We present a series of patients with subarachnoid hemorrhage (SAH) from ruptured intracranial aneurysms who were treated with endovascular embolization by detachable coils. ⋯ Endovascular coiling of ruptured intracranial aneurysms is an efficient procedure that should be performed as soon as possible after detection of an SAH.

A 48-year-old man presented with severe chest pain that had started 2 h before and ST elevation on the electrocardiogram. Cardiac computed tomography (CT) was performed using a 64-slice multidetector scanner (MDCT) to assess coronary artery stenosis at 3 h after the onset. Coronary CT angiography showed no significant stenosis at the coronary arteries, but CT myocardial images at systole demonstrated predominantly subendocardial hypoenhancement in the anterior wall. Cardiac CT that combined coronary angiography and myocardial imaging demonstrated myocardial hypoenhancement in a case of acute coronary syndrome with normal coronary arteries, which may be related to microvascular dysfunction caused by vasospastic angina or microvascular angina.

The aim of this study was to evaluate the accuracy and interobserver variability of dynamic computed tomography (CT) for diagnosis of small bowel obstruction. ⋯ There was moderate or substantial agreement for the diagnosis of small bowel ischemia between radiologists and residents. However, there was substantial agreement for the presence of closed loop obstruction.
