Sonographers can reliably handle screening breast US
December 20, 2013 -- For screening breast ultrasound studies, can sonographers deliver a performance comparable to that of radiologists? Turns out they can, according to research presented at the recent RSNA 2013 meeting in Chicago.
Quantitative 3D image analysis enables DCIS staging
December 16, 2013 -- Quantitative 3D breast image analysis of ductal carcinoma in situ (DCIS) on dynamic contrast-enhanced MRI can potentially shed light on the prognosis of these often mysterious lesions, according to research presented at RSNA 2013.
SABCS: Breast screening controversy is artificial
December 12, 2013 -- The controversy over the effect of mammographic screening on breast cancer mortality is largely contrived, according to study results presented on December 11 at the San Antonio Breast Cancer Symposium (SABCS).
Discrepancies trigger Ontario radiology peer-review program
December 11, 2013 -- Formal radiology peer review will be implemented across the province of Ontario after an 18.2% discrepancy rate was uncovered in an external review of images read by Ontario radiologist Dr. Ivo Slezic. The review's findings were released last week by Trillium Health Partners.
Saudi hospital successfully implements IORT for breast cancer
December 9, 2013 -- Intraoperative radiation therapy for early-stage breast cancer was successfully implemented in a hospital in Saudi Arabia, spurring more installations in the region, according to a presentation by Dr. Yasir Bahadur at last week's RSNA meeting.
FDG-PET/MRI aids patients with suspected pelvic malignancy
December 4, 2013 -- CHICAGO - Evidence for the efficacy of whole-body FDG-PET/MRI continues to mount, as the hybrid modality outperformed MRI alone for staging women with suspected pelvic malignancies in a study presented at RSNA 2013 on Wednesday.
Siemens RSNA launches include Force CT scanner, angio unit
December 4, 2013 -- CHICAGO - Siemens Healthcare is launching a range of new products at this week's RSNA meeting, including the third generation of its dual-source CT architecture, a new angiography system, and a major ultrasound technology upgrade.
For tomosynthesis, 2D synthetic images could replace FFDM
December 3, 2013 -- CHICAGO - Synthetically reconstructed 2D images with digital breast tomosynthesis (DBT) was comparable to conventional 2D mammography with DBT for breast cancer screening, in a study presented on Tuesday at the RSNA conference.
New Revolution CT scanner paces GE's RSNA introductions
December 3, 2013 -- CHICAGO - A new CT scanner called Revolution that acquires 16 cm of data per rotation is the RSNA 2013 highlight for GE Healthcare. The vendor is also showcasing women's imaging, a rebranding of its automated breast ultrasound technology, and a new angiography system with large-format digital detectors.
Philips paces RSNA launches with PET/CT, CT, US scanners
December 2, 2013 -- CHICAGO - New technologies being launched by Philips Healthcare at this week's RSNA meeting include a PET/CT scanner with new digital detectors, a CT system optimized for spectral imaging, and an ultrasound platform designed for both cardiology and radiology applications.
Shear-wave elastography, ABUS help classify breast lesions
December 1, 2013 -- CHICAGO - High tumor stiffness at shear-wave elastography appears to predict lymph node metastasis in women with invasive breast cancer, and automated breast ultrasound (ABUS) turned in a similar diagnostic performance to handheld ultrasound, according to two studies presented on Sunday at the RSNA meeting.
Breast density advocate Cappello tells her story in JACR
December 1, 2013 -- The driving force behind the breast density notification movement -- Nancy Cappello, PhD -- tells her side of the story in the December issue of the Journal of the American College of Radiology. In the piece, she rebuts many of the arguments made by critics of mandatory density notification.
Breast MRI use grows, but does it benefit the right women?
November 19, 2013 -- Overall use of breast MRI has increased over the past decade, but there are concerns that the modality is overused in women who don't meet screening guidelines, while being underused in those who could benefit the most, according to two studies published online November 18 in JAMA Internal Medicine.
Targeted breast radiotherapy offers treatment option
November 11, 2013 -- Targeted radiotherapy delivered to women undergoing surgery for early breast cancer could offer a feasible alternative to current procedures, which require daily radiotherapy sessions for weeks after surgery, according to two new studies published in Lancet and Lancet Oncology.
FFDM finds more high-risk lesions: But is that a good thing?
November 6, 2013 -- Transitioning from analog mammography to full-field digital mammography (FFDM) is associated with a threefold increase in the detection of high-risk lesions. But it can also result in oversurveillance and overtreatment, according to a new study published in the November issue of the American Journal of Roentgenology.
AJR: Skipped breast screenings increase cancer risk
October 29, 2013 -- When women skip a mammography screening exam -- even for just one year -- their risk of late-stage cancer increases, according to a new study published in the November issue of the American Journal of Roentgenology.
Study: CT shows promise as a breast density assessment tool
October 24, 2013 -- Breast density readings taken at CT are consistent with those acquired at mammography, according to a new study published online in Radiology. The modality could provide a readily available and more uniform option for assessing a woman's breast cancer risk, the researchers concluded.
Doctors are not informing patients of overdiagnosis risk
October 22, 2013 -- Patients are not being told about the possibility of overdiagnosis and overtreatment as a result of cancer screening programs, and many say they wouldn't start a screening program if the overdiagnosis rate is too high, according to research published online in JAMA Internal Medicine.
New breast MRI exam ready to screen women with dense breasts
October 16, 2013 -- Conventional x-ray mammography is a notoriously poor tool for screening women with dense breast tissue. Breast MRI is a possible alternative, but the cost of the exams is prohibitively high. A Michigan breast specialist believes he has changed the equation with a streamlined breast MRI screening exam that could be ready for widespread clinical use.
