We performed contiguous, 1 mm thick, magnetic resonance imaging scans in 18 men with chronic schizophrenia and in 18 age-matched healthy subjects to test in living patients the findings of a previous postmortem study. The schizophrenic patients showed bilaterally shortening (left, -6%; right, -9%) and volume reduction (left, -9%; right, -11%) of the(More)
We present a 74-year-old male patient with a mobile thoracolithiasis of 1x1 cm in diameter in the left intrathoracic space that was visualized by chest radiography and CT examinations. This calcified nodule was thought to have originated from a lipoma that had arisen from the pleura or the peripheral region of the lung, or from pericardial fat, then(More)
We used single photon emission computed tomography (SPECT) with Tc-99m-HMPAO to examine the characteristics of regional cerebral blood flow (rCBF) in five patients with bulimia nervosa (BN), eight patients with anorexia nervosa (AN), and in nine healthy controls. The SPECT examinations were performed before and after food intake stimulus, and the values of(More)
PURPOSE To compare primary tumor (18)F-fluorodeoxyglucose (FDG) maximum standardized uptake value (SUV(max)) and diffusion-weighted imaging (DWI) apparent diffusion coefficient (ADC) obtained in the same patients with head and neck squamous cell carcinoma (HNSCC) to clarify the prognostic significance of both indexes. MATERIALS AND METHODS The study(More)
OBJECTIVE We aimed to develop and assess the efficacy of a liver function index that combines liver enhancement and liver volume to standard liver volume (LV/SLV) ratio on gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced MRI. METHODS In all, 111 patients underwent a Gd-EOB-DTPA-enhanced MRI, including T1 mapping, before(More)
PURPOSE To examine the diagnostic performance of (18)F-fluorothymidine (FLT) PET/CT in primary and metastatic lymph node colorectal cancer foci in comparison with (18)F-fluorodeoxyglucose (FDG) PET/CT. METHODS The study population comprised 28 patients with 30 newly diagnosed colorectal cancers who underwent surgical resection of the primary lesion and(More)
We report a case of spontaneous retroperitoneal hemorrhage caused by rupture of an aneurysm of the right ovarian artery in a 55-year-old woman. Diagnosis was achieved by computed tomography and arteriography. The ruptured aneurysm was treated by transcatheter arterial embolization using microcoils and gelatin sponge particles. This is the first case of(More)
PURPOSE To evaluate whether the reduction rate of T1 relaxation time of the liver (T1 relaxation time index) before and 20 minutes after gadolinium-ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) injection has the potential to serve as an magnetic resonance imaging (MRI)-based liver function test in comparison with signal intensity-based(More)
Apart from relieving effects of secreted catecholamines, treatments of malignant pheochromocytoma have achieved little success. When the radiopharmaceutical, meta-[131I] iodobenzylguanidine (I-131 MIBG ), was found to concentrate in some malignant pheochromocytomas, we calculated that this agent could impart therapeutic doses of radiation to these tumors.(More)
