BACKGROUND The objective of the present study was to describe the relative frequency of myocardial bridging and dynamic compression of the coronary arteries as assessed by CT angiography and conventional angiography. METHODS AND RESULTS A total of 311 patients (208 men, 103 women; mean age 63 years) who received both 64-section CT angiography and(More)
PURPOSE To evaluate 64-section multidetector coronary computed tomographic (CT) angiography for the depiction of coronary stent fracture in patients and in vitro. MATERIALS AND METHODS This retrospective study was approved by the institutional review board, and informed patient consent was waived. The coronary CT angiograms obtained in 371 consecutive(More)
OBJECTIVE The objective of our study was to evaluate whether the SD of CT attenuation values obtained from unenhanced scans of the left atrium is a reliable parameter for the individual modulation of tube current to achieve uniform image quality in coronary CT angiography (CTA). MATERIALS AND METHODS One hundred patients (59 men and 41 women) who were(More)
Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive variant of fibrosarcoma characterized by deceptively bland histologic features and a paradoxically aggressive clinical course. The radiologic finding of this uncommon tumor has not been described to date. In this report, 3 cases of LGFMS occurring in axilla, chest wall, and pleura are presented with CT,(More)
OBJECTIVE The aim of this study was to evaluate the incidence of coronary-to-bronchial artery fistula (CBF) and clinical significance in 1300 patients examined with 64-multidetector computed tomography (MDCT) coronary angiography. METHODS One thousand three hundred ten patients underwent coronary MDCT for atypical chest pain or screening. Volume-rendering(More)
A mesothelial cyst of the round ligament is a rare cause of an inguinal mass. Clinically, it is frequently misdiagnosed as one of commoner diseases such as an inguinal hernia, femoral hernia, lipoma, and lymphadenopathy upon physical examination. Some previous reports elaborated the sonographic features of a mesothelial cyst of the round ligament. However,(More)
A stent fracture (SF) is one of the responsible factors for in-stent restenosis after a percutaneous coronary intervention. Factors that have an important role for a SF are vessel tortuosity, the presence of a right coronary artery lesion, overlapping stents, and the use of a drugeluting stent (DES) such as a sirolimus-eluting stent. Unlike with the use of(More)
Nasal-type T-cell/natural killer cell lymphoma is a new distinctive clinicopathologic entity with a characteristic immunophenotypic expression of CD56. Most cases show a predilection for the nasopharyngeal region and are referred to as nasal T/NK-cell lymphoma. Few cases occur in areas other than the nose. To the best of our knowledge, nasal type T/NK cell(More)
We report here on a case of primary extraskeletal mesenchymal chondrosarcoma that arose from the pancreas. A 41-year-old man was evaluated by CT to find the cause of his abdominal pain. The CT scans showed a heterogeneously enhancing necrotic mass with numerous areas of coarse calcification, and this was located in the left side of the retroperitoneal space(More)
