Forty-one (12%) of the screening-detected tumors had basal phenotypic expression, and these were compared with 309 (88%) nonbasal tumors. Basal-phenotype tumors were significantly more likely to manifest as an ill-defined mass (basal phenotype, 25 [61%] of 41 tumors; nonbasal phenotype, 75 [24%] of 309 tumors; p < p =" 0.019).">
Screening-detected breast tumors with a basal phenotype have a mammographic appearance different from that of nonbasal tumors. This finding may explain the good prognostic value of mammographic spiculation reported in previous studies.

The purpose of this study was to describe the imaging findings in 149 patients with pseudoangiomatous stromal hyperplasia (PASH) who had undergone at least 4 years of clinical follow-up for detection of subsequent malignancy
PASH is a common entity that presents with benign imaging features without evidence of subsequent malignant potential. At our institution, in the absence of suspicious features a diagnosis of PASH at core biopsy is considered sufficient, and surgical excision has been obviated.

Although both stayers and leavers reported satisfaction with overall
quality of service and care received at the university based locations, stayers gave higher marks than leavers.

Radiologists qualified under the Mammography Quality Standards Act supervised the performance of and interpreted breast MRI in the majority of facilities. Of 552 respondents, breast MRI was interpreted as soft copy with computer-aided detection (CAD) in 280 practices (50.7%), as soft copy without CAD in 261 (47.3%), and as hard copy in 11 (2.0%). Of 551 respondents, 256 (46.5%) never and 207 (37.6%) rarely interpreted breast MRI without correlating mammography or sonography findings. The majority of respondents never (269/561, 48.0%) or rarely (165/561, 29.4%) interpreted breast MRI performed at an outside facility. Screening breast MRI was offered at 359 of 561 (64.0%) practices. Of the practices performing contrast-enhanced examinations, 173 of 557 (31.1%) did not perform MRI-guided interventional procedures.
Contrast-enhanced breast MRI is now widely used in the United States. The information gained from this survey should provide reasonable approaches for the development of professional practice guidelines
