RATIONALE AND OBJECTIVES HER-2/neu is a valuable prognostic and therapeutic marker in primary breast carcinoma. The objective of this study was to determine the mammographic and patient characteristics (age) that correlate with HER-2/neu overexpression in primary breast carcinoma. MATERIALS AND METHODS HER-2/neu characteristics and preoperative mammograms(More)
BACKGROUND We aimed to investigate the efficacy of computer-aided detection (CAD) for MRI in the assessment of tumor extent, lymph node status, and multifocality in invasive breast cancers in comparison with other breast imaging modalities. METHODS Two radiologists measured the maximum tumor size, as well as, analyzed lymph node status and multifocality(More)
Plasma cell leukemia is a rare malignant plasma cell disorder characterized by proliferation of plasma cells in blood and the bone marrow, the outcome of which is poor with conventional therapy. More effective treatment strategies are therefore needed for this disorder. Here, we report a case of secondary plasma cell leukemia from Immunoglobulin D multiple(More)
Most well-circumscribed breast masses are benign lesions such as cysts, fibroadenomas, and intramammary lymph nodes. Nevertheless, 10%-20% of breast malignancies are well-circumscribed masses, and these malignancies include papillary, mucinous, medullary, and metaplastic carcinomas, as well as malignant phyllodes tumors. Therefore, it is important to(More)
PURPOSE To determine the clinical utility of polymerase chain reaction (PCR) for detecting Mycobacterium tuberculosis in specimens from percutaneous transthoracic needle aspiration (PTNA). MATERIALS AND METHODS PCR for M tuberculosis detection in specimens from PTNA was performed prospectively in addition to cytologic and histologic analyses in 45(More)
OBJECTIVE This study evaluated the anatomic significance and sites of aortic bifurcation, right renal artery, and conus medullaris when locating lumbar vertebral segments on MRI. SUBJECTS AND METHODS. The study group was composed of 210 patients who underwent MRI of the lumbosacral spine. The position of aortic bifurcation was evaluated using MRI. Midline(More)
To determine if the improved contrast resolution of full-field digital mammography (FFDM) with reduced spatial resolution allows for superior or equal phantom object detection compared with screen-film mammography (SFM). Tissue equivalent breast phantoms simulating an adipose to glandular ratio of 50/50,30/70, and 20/80 were imaged according to each(More)
PURPOSE To review the computed tomographic (CT) features of segmental misty mesentery (SMM) in 29 patients and assess the primary causes of this CT finding. MATERIALS AND METHODS The authors analyzed the medical records and CT features of SMM in 29 patients. CT images were evaluated for the site, thickness, and vascular changes of the involved mesentery;(More)
PURPOSE To evaluate radiological findings of non-calcified ductal carcinoma in situ (DCIS) and to correlate those with histological features. MATERIALS AND METHODS From July 2002 to March 2006, 22 patients with histologically-proven non-calcified DCIS were included. Mammography was obtained in 19 patients, ultrasound in 18 patients, and both examinations(More)
PURPOSE To determine the speed, accuracy, ease of use, and user satisfaction of various electronic data entry platforms for use in the collection of mammography clinical trials data. METHOD AND MATERIALS Four electronic data entry platforms were tested: standalone personal digital assistant (PDA), Tablet PC, digitizer Tablet/PDA Hybrid (DTP Hybrid), and(More)
