Patients with CIN after CT show poor 1-year outcomes
September 2, 2015 -- Patients who develop contrast-induced nephropathy (CIN) are at high risk of major adverse events one year after imaging with contrast-enhanced CT, according to a new study in the September Annals of Emergency Medicine. The experience in more than 600 patients who underwent contrast CT suggests the problem is both serious and underrecognized.
iPhone works well in a pinch for cardiovascular emergencies

August 26, 2015 -- Initial CT findings in patients suspected of having appendicitis are a largely untapped source for predicting hospital costs and resource utilization down the line, according to a new study in the September issue of the American Journal of Roentgenology.
Feedback helps docs adhere to CT imaging guidelines
August 19, 2015 -- For reducing inappropriate CT scans, clinical decision-support software is a good place to start. But the software alone isn't enough to get doctors to comply, according to a study in the American Journal of Roentgenology. The researchers found that letting doctors know their ordering patterns are being watched can help.
CCTA, SPECT MPI yield similar outcomes in chest pain
August 13, 2015 -- Although they provide different radiation exposure levels and patient experiences, SPECT myocardial perfusion imaging (MPI) and coronary CT angiography (CCTA) produce remarkably similar outcomes in initial imaging for chest pain, according to a new study.
Proper documentation can maximize 3D reimbursement
August 12, 2015 -- Medicare's recovery audit contractors are on the lookout for 3D reconstruction billing that does not meet the standards to support medical necessity.

But when smokers know that CT lung cancer screening is available, almost half opt to continue smoking, according to a new study in JAMA Internal Medicine.
CT dose alerts show important but limited utility
August 10, 2015 -- CT radiation dose alerts have their strengths and certainly their weaknesses, according to a study from Boston. But for better or worse, the alerts are mandatory under the Smart Dose (XR-29) rules that took effect last month. So radiologists must comply -- while still looking for ways to improve the new standard.
