PET myocardial blood flow finds under-diagnosed multivessel CAD

October 3, 2013

Evaluating myocardial blood flow (MBF) with stress-rest cardiac PET teases out more multivessel CAD than with cardiac PET or SPECT alone, both of which tend to underestimate severity of disease, according the proceedings of the 2013 American Society of Nuclear Cardiology (ASNC) 2013 Annual Meeting held Sept. 26-29 in Chicago.

Junyang Lou, MD, a cardiologist at Cleveland Clinic, and colleagues conducted a retrospective study of 190 patients at the institution who underwent Rubidium-82 cardiac rest and Regadenoson stress cardiac PET from December 2010 to March 2013. Researchers analyzed the data and calculated MBF to determine additional multivessel disease.
