BACKGROUND Myocardial bridge (MB) is a common anatomical condition, under which a part of the coronary artery running in the epicardial adipose tissue, is covered with myocardial tissue. It regulates atherosclerosis development and sometimes evokes coronary heart disease through haemodynamic alterations. We attempted to efficiently detect MB and evaluate(More)
The differences regarding adverse reactions in different low-osmolar non-ionic contrast media had not been investigated previously. Thus, the aims of this study were to identify differences in the incidence of adverse reactions in five different low-osmolar non-ionic contrast media. We prospectively recorded all adverse events associated with five different(More)
The aim of this study was to analyze the fraction defectiveness and efficacy of the patient immobilization device (PID) for pediatric chest radiography. We examined 840 plain chest radiographs in six hospitals, including four children's hospitals and two general hospitals. The mean age of the patients was 1.9 years (range 0–5 years). Two board-qualified(More)
We report an extremely rare case of wandering spleen (WS) complicated with gastric volvulus and intestinal non-rotation in a male adult. A 22-year-old man who had been previously treated for Wilson disease was admitted with severe abdominal pain. Radiological findings showed WS in the midline of the pelvic area. The stomach was mesenteroaxially twisted and(More)
PURPOSE Visceral fat-type obesity is known to be closely related to hyperlipidemia and diabetes. The visceral fat area/subcutaneous fat area ratio is used for the diagnosis of visceral fat-type obesity. In this study, we measured the visceral and subcutaneous fat areas in the fat images obtained using 0.3 Tesla open-type MRI, and investigated their(More)
Thirty-nine cases of hepatocellular carcinoma (HCC) out of 55,135 examinees were examined. The diagnostic problems of ultrasonography (US) in detecting HCC and the risk value of 10 factors in HCC were discussed. We also propose the surveillance programs for HCC in Multiphasic Health Testing and Services (MHTS). US will be performed at 3-, or 6 monthly(More)
We studied the effect of acetazolamine (DIAMOXR) on vascular response in areas with crossed cerebellar diaschisis (CCD) using consecutive 99mTc-hexamethyl-propyleneamine oxime (HMPAO) SPECT studies before and after DIAMOX administration with a subtraction method. Regions of interest were drawn over the bilateral cerebellar cortices and interhemispheric(More)
A case of a 78-year-old man with delayed visualization of the gallbladder during in vivo labeling for 99mTc-red blood cell scintigraphy for gastrointestinal bleeding is reported. The patient had several episodes of renal failure, melena, anemia, blood transfusion, and hemodialysis. The mechanism of this unusual phenomenon is not clear; however, excess(More)
The purpose of this study was to develop a new technique for diffusion-weighted MRI (DWI) with a low-field scanner. DWI is becoming important for assessment of acute stroke. Until recently DWI required expensive technology. We developed multishot-DWI sequence for 0.3T open type MR imager. We prospectively studied forty patients on this 0.3T MRI and compared(More)
AIM To ascertain therapeutic effectiveness and adverse reactions with radiochemotherapy for locally invasive bladder cancer, comparison was made between two-port and four-port irradiation with intravenous cisplatin administration. METHODS In 86 patients who were diagnosed with locally invasive bladder cancer on the basis of imaging and biopsy findings,(More)
