To evaluate the ability of high-resolution computed tomography (HRCT) to detect longitudinal changes in structural abnormalities caused by smoking, HRCT and pulmonary function tests were used to examine nonsmokers, current smokers, and past smokers annually for 5 yr. Inspiratory HRCT was taken for the upper, middle, and lower lung fields, while expiratory(More)
Anorectal anomalies were evaluated by computed tomography (CT) scanning in 23 patients. CT scans showed clearly the anatomy of the anal sphincter muscles in relation to the intestine and the amount of muscle mass present. These findings correlated well with the results of direct visualization and electromyograms in patients who underwent surgery. The(More)
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)
PURPOSE To describe the characteristics of pancreatoblastoma. MATERIAL AND METHODS We studied 3 cases of pancretoblastoma and reviewed another 59 cases. Parameters analyzed were tumor site, hemorrhage, capsule formation, necrosis, vascularity, production of alpha-fetoprotein (AFP), cystic changes and calcification. RESULTS The diagnostic findings were(More)
Using a newly developed InP/InGaAsP multichannel detector, we developed a near-infrared Raman spectroscopic system that can measure human tissues efficiently without interference from fluorescence. This enabled us to measure an in vivo Raman spectrum of live human tissue (skin) in 1 min using fiber probe optics. By applying this system to human lung(More)
Fifty-nine patients (57 females, two males) with Takayasu arteritis were retrospectively evaluated. Chest radiographs were abnormal in 68% of patients in whom they were obtained (n = 49). Aortic contour changes and calcification were frequent findings. Sixty-eight percent of patients who underwent total aortography (n = 50) had panaortitis, and 28% had(More)
A new fiberoptic bronchoscope, the BF-2.2T, has been designed to go through the 2.6-mm channel of the conventional fiberoptic bronchoscope (Olympus BF-1T20). It measures 2.2 mm in outer diameter; it has a visual angle of 75 degrees, a range of observation of 3 to 50 mm, an effective length of 1,150 mm, and a total length of 1,400 mm. It bends at 120 degrees(More)
We report the case of a sporadic gastric submucosal neurofibroma underneath a T1 stage cancer. A 61-year-old man underwent gastroscopy because of epigastralgia and was diagnosed as having T1 stage gastric cancer by an experienced gastroenterologist. Subsequently performed computed tomography (CT) showed poorly circumscribed wall thickening underneath the(More)
We present two cases of malignant solitary fibrous tumor of the pleura (MSFT-P) and review 29 reported cases of MSFT-P. In examining the clinical and morphological features and prognosis of MSFT-P, we found that over 90% of the patients had some symptoms and one-third showed local recurrence. Chest radiographs and CT demonstrated large broad-based masses(More)
