introduction in recent years methods based on radio frequency waves have been used for detecting breast cancer. using theses waves leads to better results in early detection of breast cancer comparing with conventional mammography which has been used during several years. materials and methods in this paper, a new method is introduced for detection of backscattered signals which are received by...
conclusion gm presents with a wide range of conventional radiological findings, hampering the diagnosis. in patients with inconclusive conventional findings, mri may assist in the differential diagnosis and assessment of the extent of disease. however, a definitive diagnosis and relevant treatment require histopathological confirmation. objectives the aim of this study was to review the radiolo...
conclusion our study suggests that breast mri findings of igm have a wide spectrum. rim enhancement patterns are frequently seen on contrast enhanced images, but the imaging findings are nonspecific and cannot be used definitively to distinguish between benign and malignant lesions. patients and methods a retrospective analysis was conducted on 20 patients with igm who had been diagnosed by nee...
Benign breast diseases constitute a heterogeneous group of lesions including developmental abnormalities, inflammatory lesions, epithelial and stromal proliferations, and neoplasms. In this review, common benign lesions are summarized and their relationship to the development of subsequent breast cancer is emphasized.

Background: Average glandular dose (AGD), entrance skin air kerma (ESAK) and normalized glandular dose (DgN) are the main dosimetric quantities in mammography. Breast tissue composition is one of the factors affecting on DgN values. In this study both homogeneous and heterogeneous breast tissue is assumed and its impact on DgN values are evaluated. Methods: Homogeneous breast phantom with diffe...
background: transvaginal ultrasound is one of the most common means to examine endometrial cavity lesions although its negative results are more valuable. saline sonohysterography can reduce the number of false negative rates of endometrial lesions diagnoses in tamoxifen consumers. the objective of this study was to determine the diagnostic values of saline infusion sonohysterography (sis) and ...
Breast cancer is the most common cancer and the second most common cause of death from cancer in women.The aim of this studywas to determine which is more accurate imaging test mammography or ultrasound for diagnosis of breast cancer based on the women's age and breast density. We examined 546 patients with breast symptoms, by clinical breast examination, mammography and ultrasound. A total of ...
A 41-year-old female presented at the department of radiology because of multiple slowly growing lumps in both breasts. Mammography showed dense breast tissue with multiple wellcircumscribed round lesions with no calcification. At ultrasound, sharply defined, heterogeneous oval masses were seen. On T2-Weighted Images (WI), the lesions were heterogeneous and hyperintense. T1-WI after intravenous...
OBJECTIVE The purpose of this research work was to evaluate complex cystic breast lesions by advanced MRI techniques and correlating imaging with histologic findings. METHODS AND MATERIALS In a cross-sectional design from September 2013 to August 2015, 50 patients having sonographically detected complex cystic lesions of the breast were included in the study. Morphological characteristics wer...
