Using sophisticated mapping technology, census data, and state cancer registry statistics, researchers from Georgia established a link between the presence of Mammography Quality Standards Act-certified mammography centers and lower death rates from breast cancer.

Despite growing concern over CT-related radiation exposure, measuring cumulative exposure from CT imaging in a standardized or formal way is not part of routine practice for ordering physicians in the emergency department, according to a presentation this week at the 2009 RSNA meeting.

Carestream Health showed at the RSNA meeting a work-in-progress upgrade to its PACS that will allow cross-site reading through a unified global work list.

SuperSonic Imagine returned to the RSNA exhibit floor with FDA clearance to market its Aixplorer ultrasound system in the U.S.

CT vendors have been talking for months about the potential of iterative reconstruction as the next big thing to substantially reduce the worrisome radiation dose patients are exposed to during multislice CT imaging. Now they have results of a large multicenter cohort study to add substance to their enthusiasm.

To prevent errors and misunderstandings, referring clinicians and radiologists must show more restraint when using abbreviations, a U.K. study has found.

“Hedge” statements were found in nearly a third of radiology reports using a computer-based review system described in an award-winning paper presented Tuesday at the RSNA meeting.

MRI is the best method to assess breast cancer tumor size prior to surgery and after chemotherapy, according to findings from the American College of Radiology Imaging Network trial 6657. Size on mammography does not correlate with true residual disease in patients treated with neoadjuvant chemotherapy and thus MRI is the best modality, the researchers said.

Radiation from mammography screenings may increase the chances of developing breast cancer for women at high risk, according to findings presented Tuesday at the 2009 RSNA meeting.

Findings of a study by California researchers suggest MR imaging could be a highly accurate tool in the detection of placenta accreta, the leading cause of death in women directly before or after childbirth

Ultrasound elastography could be an effective means of reducing unnecessary breast biopsy, according to an ongoing study presented Monday at the 2009 RSNA meeting.
