Percutaneous image-guided biopsy of renal masses is safe and accurate

For the study, the researchers reviewed 153 kidney biopsies in 126 patients. The researchers found that more than 60% of patients had a change in their treatment--whether surgery, tumor ablation, chemotherapy or radiation--due to biopsy results, and that as many as 75 unnecessary kidney removals were potentially avoided.

New radiation protection technique significantly reduces physician radiation exposure during coronary angiography

Using the new device, physicians monitor patients' angiograms and control exam table movement from behind a lead plastic shield. A newly developed extension bar allows the physician to remain safely behind the shield and still retain table control for panning, according to Martin Magram, MD, developer of the new technique and assistant professor in the department of diagnostic radiology.
