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. Study results were published in the January 2 issue of the Journal of the American Medical Association.
SBRT halves cost vs. IMRT for prostate cancer January 3, 2013 -- As members of Congress grapple over ways to reduce the U.S. budget, the publication on December 27 in the American Journal of Clinical Oncology of a complex model analyzing the costs of radiation therapy for prostate cancer seems particularly timely.
Lymph node ratio predicts RT benefit for oral cancer January 3, 2013 -- Radiation therapy (RT) can benefit some patients with oral cavity squamous cell carcinoma, but they can suffer acute as well as long-term toxicities. The use of lymph node ratios may help identify which patients will benefit the most, according to an article published online in Radiotherapy and Oncology.
House signs off on SGR bill with $800M in imaging cuts January 2, 2013 -- The U.S. House of Representatives voted on January 1 to approve the Senate's fiscal cliff bill that averts a 27% reimbursement cut due to the sustainable growth rate (SGR) formula. But the legislation also includes $800 million in Medicare cuts to advanced medical imaging services -- on top of additional cuts proposed in 2012.
Resident program managers struggle to balance new demands January 2, 2013 -- As program managers begin to implement far-reaching changes in radiology residency education, most believe they'll need to limit the options available to their residents to choose their own path -- particularly in the fourth year of training -- to ensure a good basic education for core residents, according to a survey presented at RSNA 2012.
MRI can detect breast cancer in average-risk women January 2, 2013 -- A study by German researchers shows MRI screening can help detect breast cancer in women who are only at average risk of developing the disease and have no personal or family history of breast cancer.
