A Doctor’s Mammogram Mission Turns Personal
Dr. Marisa Weiss scheduled her mammogram this spring, just as she does every year. She had just turned 51, and after having annual scans for a decade, she knew what to expect: her dense breast tissue made reading the films difficult — “like looking for a polar bear in a blizzard” — and the technician would probably ask her to sit for a few extra views…

Contrast Digital Mammo Matches MRI in Cancer Detection
Contrast-enhanced dual-energy digital mammography matches MRI in cancer detection, with fewer false positives, according to research presented at this month’s RSNA meeting. The findings could position contrast mammography as an alternative to more expensive breast MRI scans…

Mayo Tracking Radiation Exposure
Mayo Clinic has developed an in-house medical imaging exam tracking system to enable the monitoring of a patient’s radiation exposures over time.The DICOM Index Tracker is being used at Mayo sites in Scottsdale, Ariz., and Rochester, Minn. The application tracks dose and scanner utilization, among other information, for any type of digital imaging. Data is converted into an accessible format and placed in a central repository…

AHA: Protocol Reduces Children’s Radiation Exposure During EP Procedures
A protocol that uses continuous real-time radiation monitoring, low-dose imaging programs and requires physician awareness of radiation dose significantly reduced radiation exposure during electrophysiology (EP) procedures in children, according to research presented at the annual meeting of the American Heart Association’s Scientific Sessions earlier this month in Chicago…

Women With Breast Cancer History Should Consider MRI: Study
Women who have had breast cancer should consider annual screening with breast MRI in addition to an annual mammogram, new research indicates. Currently, the American Cancer Society recommends annual breast MRI plus mammography for women at very high risk for breast cancer, such as those with a known genetic mutation known as BRCA or those with a very strong family history. But it takes no position on MRI imaging for women who have had breast cancer, saying there is not enough evidence to recommend one way or the other…

Tough To Say No To CT Scans In Emergency Rooms
A trip to the emergency room today is likely to trigger a round of routine diagnostic tests from blood work to an electrocardiogram to a urine sample. And increasingly, there’s one more on that list: the CT scan. A new study shows that CT, or computerized tomography, has increased in ERs nearly six-fold since 1995 and shows no sign of tapering off…

CDC: Nearly Half of Cervical and Colorectal Cancers Caught Late
Despite the availability of screening tests, almost half of cervical and colorectal cancer cases in the U.S. are diagnosed at late stages, when the disease is more difficult to treat. That’s the conclusion of a CDC report out today, which also found that a third of breast-cancer cases are caught at a late stage. “More work is needed to widely implement evidence-based cancer screening tests which may lead to early detection and, ultimately, an increase in the number of lives saved,” said Marcus Plescia, director of the CDC’s division of cancer prevention and control, in a statement…
