The Potential Impact of Risk-Based Screening Mammography in Women 40-49 Years Old.

Objective: The purpose of this study was to determine the prevalence of very strong family history and extremely dense tissue in women 40-49 years old with breast cancer detected on screening mammography.

Materials And Methods: All cancers detected by screening mammography at our institution between January 1997 and November 2012 in 40- to 49-year-old women were retrospectively identified. Those with a personal history of breast cancer were excluded.

Advanced gastrointestinal endoscopic procedures: indications, imaging findings, and implications for the radiologist.

There are a variety of advanced gastrointestinal endoscopic procedures, many of which are guided by endosonography, which are performed by interventional gastroenterologists or minimally-invasive surgeons. The purpose of this pictorial review is to briefly describe several advanced gastrointestinal endoscopically guided procedures, to review the implications for radiologists interpreting the associated imaging examinations, and to demonstrate the expected preprocedural imaging findings, as well as the expected and the unexpected postprocedural findings, in patients undergoing these procedures.

Endometriosis of abdominal and pelvic wall scars: multimodality imaging findings, pathologic correlation, and radiologic mimics.

Implantation of an endometriotic lesion within a pelvic or abdominal wall scar is an uncommon but well-described condition that may be the underlying cause of acute or chronic recurrent abdominal or pelvic pain, especially after cesarean section. Radiologists may not consider scar endometriosis when it is encountered at cross-sectional imaging. Cesarean section scars are the most common site of extraovarian or extrauterine endometriosis.
