Most radiologists don't meet Medicare quality reporting rules January 8, 2013 -- More than three-quarters of radiologists are not meeting requirements of the Medicare Physician Quality Reporting System, according to a study to be published in the February issue of the Journal of the American College of Radiology. The shortfall could expose radiologists to penalties starting in 2015.
Use of imaging in inpatient setting lags overall growth January 8, 2013 -- Use of noninvasive diagnostic imaging in the hospital inpatient setting lagged overall imaging growth from 2000 to 2010, and the share of imaging being done on an inpatient basis dropped from 32% to 25%, said Dr. Vijay Rao from Thomas Jefferson University.
New technologies drive Medicare breast screening costs higher January 7, 2013 -- Medicare costs for breast screening are being driven higher by new technologies such as digital mammography and computer-aided detection, which are being adopted in spite of limited data on their effectiveness, according to a study published on Monday in JAMA Internal Medicine.
Use of ultrasound to guide central venous catheters lags January 7, 2013 -- Despite compelling clinical evidence and recommendations from a number of organizations, utilization of ultrasound to guide placement of central venous catheters still remains low, according to a recent presentation.
Practice of Ultrasound: Part 9 -- Image quality January 4, 2013 -- AuntMinnie.com presents the ninth in a series of columns on the practice of ultrasound from Dr. Jason Birnholz, one of the pioneers of this modality. In this installment, he illustrates why everything depends on image quality.
3D/4D ultrasound imaging: Coming of age January 4, 2013 -- Although high-performance 3D/4D technology has been available in ultrasound for years, it hasn't routinely been used in all clinical practices. That may change in 2013, however, thanks to a number of key trends that are expected to drive widespread adoption.
Don't redo CT for mild head trauma if patient is stable January 4, 2013 -- An initial CT exam after mild head trauma is a good idea because it can show bleeding in the brain. Repeating the scan, however, is unlikely to yield additional benefits or change management if the patient is stable, according to a new study in the January issue of Neurosurgery.
Brain fMRI shows negative effect of fructose on eating habits January 3, 2013 -- Using functional MRI (fMRI), Yale University researchers may have uncovered one of the keys to the obesity epidemic: that ingestion of fructose changes brain activity in regions that regulate appetite and produce feelings of being full.
