Digital breast tomosynthesis boosts reader accuracy, cuts recall rate
By Kathlyn Stone
Digital breast tomosynthesis (DBT) boosts radiologists' cancer detection rates compared to full-field digital mammography (FFDM) alone, according to a multicenter, multireader study that evaluted reader performance with DBT. For this study, a dozen radiologists at five clinics took part in the trial, which compared radiologists' cancer detection rates and screening recall rates using DBT.

Preop MRI can improve breast cancer surgical outcomes, study says
By Kate Madden Yee
The use of MRI for the diagnosis and staging of breast cancer remains controversial, with some clinicians advocating for its use and others claiming that its value is unproven. Despite all this attention, whether breast MRI positively influences surgical outcomes in women with diagnosed breast cancer has not yet been studied extensively.

CPOEs prompt better communication in the ED
By Wayne Forrest
When using a computerized provider order entry (CPOE) system, emergency department (ED) physicians tend to provide more details on a patient's medical history and on clinical questions for ED radiologists. That enhanced communication leads to better interpretation and results in ED studies, according to radiologists at Massachusetts General Hospital in Boston.

RSNA studies advance ultrasound's role in breast cancer detection
By Edward Susman
The preliminary results of the ACRIN 6666 trial show that ultrasound boosts cancer detection but at the risk of a higher false-positive rate. While the trial investigators continue to mine the trial data to find the best place for the modality in a screening setting, other researchers are using advanced imaging technology such as 3D and computer-aided analysis tools with ultrasound to enhance breast imaging.

CTA of the pancreas reduces failed resections
By Eric Barnes
Used as a preoperative planning tool, multidetector-row CT angiography reduces the number of aborted pancreatic resections, according to new research from Beth Israel Deaconess Medical Center in Boston. The retrospective study found that the addition of contrast significantly improved the detection of vascular invasion that prevented curative resection.

TMJ imaging benefits from digital tomo technique
By Brian Casey
Japanese researchers have produced good results using a digital tomosynthesis technique for general radiography studies of the temporomandibular joint (TMJ). As part of its research, the group also developed a new reconstruction algorithm for digital tomo studies that they say reduces image artifacts in the 3D volumes generated by the digital tomo system they used.
