OBJECTIVE Our objective was to assess our experience in diagnosing pure tubular carcinoma of the breast and to correlate the radiologic and histopathologic features. MATERIALS AND METHODS A retrospective review of 932 consecutive cases of proven breast cancer diagnosed between 1990 and 1997 revealed 78 cases (8.4%) of tubular carcinoma in 69 patients.(More)
The success rate with the traditional 14-gauge, core-biopsy, multiple-pass technique was compared with that of a directional vacuum-assisted device in sampling calcification clusters in the breast. Of the 130 focal calcification clusters sampled with the multiple-pass technique, 12 clusters (9.2%) had no particles depicted on radiographs of the specimen.(More)
PURPOSE To classify lesions initially considered nonmalignant at large-needle core biopsy that were subsequently surgically excised or sampled at repeat biopsy. MATERIALS AND METHODS From August 1, 1991, to December 31, 1996, 1,032 breast abnormalities (214 malignant and 818 nonmalignant lesions) were sampled at large-needle core biopsy. Of the(More)
PURPOSE To investigate the utility of dynamic contrast-enhanced gradient-echo MR imaging of head and neck lesions and to compare this technique with the commonly used spin-echo contrast-enhanced fat-saturation technique. METHODS Twenty-two patients with a total of 23 head and neck neoplasms underwent dynamic gradient-echo and spin-echo MR imaging studies.(More)
BACKGROUND AND OBJECTIVE Liver cancer is the tenth most common cancer in the USA, and its incidence has been increasing for several decades. Early detection, diagnosis, and treatment of the disease are very important. Computed tomography (CT) is one of the most common and robust imaging techniques for the detection of liver cancer. CT scanners can provide(More)
OBJECTIVE Due to the limitations of the small single incision, an ideal preoperative localization technique is essential for surgical resection of small pulmonary nodules by uniportal video-assisted thoracoscopic surgery (VATS). The aim of this study is to evaluate the usefulness and safety of preoperative computed tomography (CT)-guided patent blue vital(More)
BACKGROUND Microwave ablation (MWA) of lung tumors is a new approach for local tumor control. The purpose of this retrospective study was to evaluate the preliminary results of safety and efficacy of MWA with a dynamic frequency range (902-928 MHz) and power (10-32 W) for local tumor control of thoracic malignancies. METHODS From December 1, 2013 to(More)
UNLABELLED Coronary computed tomographic angiography (CCTA) has been widely available since 2004. After that, the diagnostic accuracy of CCTA has been extensively validated with invasive coronary angiography for detection of coronary arterial stenosis. In this paper, we reviewed the updated evidence of the role of CCTA in both scenarios including acute(More)
PURPOSE To evaluate the utility of cytologic analysis of fluid obtained from impalpable breast cysts by means of radiologically guided aspiration. MATERIALS AND METHODS The authors retrospectively reviewed the reports of cytologic examinations of fluid obtained with sonographically or mammographically guided aspiration of 660 impalpable breast cysts in(More)
BACKGROUND Preoperative computed tomography (CT)-guided localization of small lung nodules is important for accurate and efficient video-assisted thoracoscopic surgery (VATS). Resection of multiple small pulmonary nodules in one VATS procedure can aid in patient management. The aim of this study was to evaluate the usefulness of CT-guided Patent Blue V(More)
