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)
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)
OBJECTIVE To compare image quality and diagnostic accuracy of 2D with 3D ultrasonography in solid breast masses. METHODS AND MATERIAL To rate image quality, two radiologists compared lesion contrast and characterization of 507 solid breast masses in 2D and 3D ultrasonography and then graded the 3D imaging in 3-point scale. To characterize the masses, the(More)
BACKGROUND AND PURPOSE Ultrasound has been used successfully to differentiate benign and malignant breast lesions. The aim of this study was to investigate the correlation between ultrasound and prognostic indicators in breast cancer such as histological type, tumor grade, and biological markers. MATERIALS AND METHODS Ultrasound findings (shape, margin,(More)
RATIONALE AND OBJECTIVES Diagnostic mammography is performed on women with clinical symptoms that suggest breast cancer or women for whom further mammographic evaluation has been requested because of an abnormal screening mammography. We assessed whether the use of full-field digital mammography would improve the positive predictive value (PPV) for the(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)
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)
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)
