OBJECTIVE Few studies have reported on injury of the mammillothalamic tract (MTT) in patients with stroke. However, no study in patients with subarachnoid haemorrhage (SAH) has been reported. Using diffusion tensor tractography, we attempted to investigate injury of the MTT in patients with SAH. METHODS We recruited 16 patients with SAH and 15 control participants. DTI was obtained at 5.7±1.5...

BACKGROUND AND PURPOSE Early diagnosis of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage is critical but difficult. We analyzed diagnostic threshold values of CT perfusion for use in detection of DCI in patients with subarachnoid hemorrhage. METHODS We prospectively enrolled patients with subarachnoid hemorrhage with CT perfusion on admission and at time of clinical ...

BACKGROUND In the operating room (OR), poor communication among the surgeons, anesthesiologists, and nurses may lead to adverse events that can compromise patient safety. A survey performed at our institution showed low communication ratings from surgeons, anesthesiologists, and OR nursing staff. Our objective was to determine if communication in the operating room could be improved through med...

BACKGROUND Cerebral perfusion can be evaluated using a computed tomography (CT) scan by intravenous bolus injection of contrast media. The purpose of this study was to investigate the value of CT perfusion (CTP) in follow-up of extracranial-intracranial (EC-IC) bypass surgery. METHODS We retrospectively reviewed pre- and postoperative CTP studies in 14 patients who received EC-IC bypass surge...

BACKGROUND Lymphoscintigraphy has often been used for evaluating arm lymphatic dysfunction, but no optimal approach for quantification has so far emerged. We propose a quantifiable measure of lymphatic function that we applied in patients treated for breast cancer. METHODS Eleven patients, aged 34-68 years, with unilateral arm lymphedema following breast cancer treatment underwent bilateral l...
