New Study Questions Over-Diagnosing in Mammography

The most recent Canadian National Breast Screening Study (CNBSS) reveals that data from a 25-year follow-up period shows 22 percent of invasive breast cancers detected through mammography screening were over-diagnosed. The researchers of this study point out that this study should not be generalized to every nation, but that physicians should reevaluate the use of mammograms in cancer screenings. The American College of Radiology and Society of Breast Imaging find the CNBSS report to be misleading.
Breast Cancer More Easily Detected With New Phase Contrat
Researchers have made new developments in X-ray phase-contrast mammography, which provides images in higher contrast. This could help doctors detect premalignant and malignant breast lesions without using invasive procedures. It is not yet ready for clinical use until it has been validated in a larger number of studies, but researchers are excited about the early findings.
Study Suggests Concussion Effects Last Longer for Men than Women

When it comes to concussions, radiologists historically have had to rely on patient reports of pain and symptoms. However, with new diffusion tensor imaging (DTI), physicians can now see effects of brain injury at a microscopic level. One of the interesting things they have noticed since they can now see this kind of injury is that the effects of concussions last more than twice as long for men as they do for women.
