CMS corrects codes, raises MPI, CT fees
By AuntMinnie.com staff writers
The U.S. Centers for Medicare and Medicaid Services (CMS) on May 6 issued a correction to its previously announced codes for the Medicare Physician Fee Schedule for 2010, with the end result being higher reimbursement for SPECT myocardial perfusion imaging (MPI) and cardiac CT scans.

Researchers eye dual-energy DR as calcium-scoring option
By Brian Casey
Could digital radiography (DR) become an alternative to CT for coronary artery calcium scoring? Some U.S. researchers think so -- they've developed a DR-based dual-energy subtraction algorithm that with further refinement could provide calcium scores at a lower cost and radiation dose than CT.

CT calcium scores boost value of cardiac risk factors
By Eric Barnes
A new analysis of a major cardiac risk study published today in the Journal of the American Medical Association found that CT coronary artery calcium scoring significantly boosts the power of traditional risk factors for predicting adverse cardiac events over the long term.

Coronary CTA best next test for positive stress patients
By Eric Barnes
Asymptomatic individuals with positive cardiac stress results should proceed to coronary CT angiography (CTA) rather than an invasive cardiac catheterization, according to a new report in the May American Journal of Roentgenology. The study found that low-risk patients received more cost-effective care by using coronary CTA as a gatekeeper test.

Less DNA damage seen after high-pitch coronary CTA
By Eric Barnes
High-pitch dual-source CT angiography (CTA) scans produce significantly less radiation-related DNA damage than comparable low-pitch dual-source CTA scans -- and, importantly, the DNA results correspond to both measured and derived biological radiation doses, say researchers from Erlangen, Germany.

Carotid ultrasound may help predict cardiac events
By Eric Barnes
Performing ultrasound studies of carotid intima-media thickness provides long-term prognostic value for adverse cardiac events, giving doctors important clues about who is at risk for a heart attack, according to a study published April 6 in the Journal of the American College of Cardiology.

4D MRI identifies abnormal flow patterns in thoracic aorta
By Wayne Forrest
Using 4D flow MRI to show abnormal systolic flows in the aortas of patients with a bicuspid aortic valve, researchers in California hope to identify patients at risk of developing ascending aortic aneurysm. Results of the research are published in the April issue of Radiology.

Cardiac cath delivers high radiation doses to operators
By Eric Barnes
The rapid development of new cardiac stents and other medical devices is opening up a world of possibilities for interventional procedures in the cath lab -- but it's also exposing equipment operators to ever-higher radiation doses.

PET-guided treatment reduces events in heart patients
By Wayne Forrest
Canadian and American researchers observed a "significant reduction" in cardiac events when using FDG-PET rather than standard methods of care to determine which patients receive revascularization therapy, according to research published in the April issue of the Journal of Nuclear Medicine.
