Between October 1997 and May 1998, they had(More)
BACKGROUND AND PURPOSE The natural history of symptomatic, untreated posterior circulation stenosis is dismal, with many patients experiencing significant morbidity or mortality. The purpose of this study was to evaluate the feasibility and results of stent-assisted angioplasty of symptomatic intracranial vertebrobasilar artery stenosis. METHODS We(More)
This study was designed to investigate the mammography and ultrasound findings of triple-negative breast cancer and to compare the results with characteristics of ER-positive/PR-negative/HER2-negative breast cancer and ER-negative/PR-negative/HER2-positive breast cancer. From January 2007 to October 2008, mammography and ultrasound findings of 245 patients(More)
BACKGROUND AND OBJECTIVES To evaluate the toxicity and efficacy of stereotactic body radiotherapy (SBRT) for the treatment of localized hepatocellular carcinoma (HCC) in the absence of another standard treatment option. METHODS The authors reviewed the details of 38 patients with inoperable HCC (diameter <10 cm) treated by SBRT in a prospectively(More)
The objective of this study was to describe the mammographic and sonographic appearances of primary lymphoma of the breast. We retrospectively reviewed the mammographic and ultrasonographic images of 12 patients with primary lymphoma of the breast. Descriptions of imaging findings were made according to the Breast Imaging Reporting and Data System lexicon(More)
BACKGROUND Impairment of cognitive function is often present in patients with carotid artery stenosis but the details of this dysfunction have rarely been reported. Our purpose was to elucidate the cognitive dysfunction in patients with unilateral severe carotid stenosis using comprehensive neuropsychological testing, and also to identify the specific(More)

MATERIALS AND METHODS We studied 142 patients (79 premenopausal, 63 postmenopausal) who underwent mammography, ultrasonography, and breast MR. We(More)
Obstructive jaundice is frequently present in patients with advanced gastric carcinoma. The purpose of this study was to assess the cause and preferential site of bile duct obstruction in patients with gastric carcinoma and to evaluate correlativity of biliary obstruction with the nature of the primary gastric lesion. Cholangiographic findings of 54(More)
BACKGROUND Although computer-aided evaluation (CAE) programs were introduced to help differentiate benign tumors from malignant ones, the set of CAE-measured parameters that best predict malignancy have not yet been established. PURPOSE To assess the value of the central washout sign on CAE color overlay images of breast MRI. MATERIAL AND METHODS We(More)
The computed tomographic (CT) findings of 13 cases of calcified gastric carcinoma were analyzed retrospectively. Eleven cases were confirmed as a mucinous adenocarcinoma by surgery (three cases), or endoscopic biopsy (eight cases). Two cases were diagnosed as adenocarcinoma by endoscopic biopsy. In all cases the calcifications were of the punctate or(More)
