DENVER—Coronary CT Angiography (CCTA) is not indicated for use in atrial fibrillation (AF) patents due to the problems it causes in terms of diagnostic accuracy, Thomas C. Gerber, MD, PhD, of the division of cardiovascular diseases at the Mayo Clinic, Jacksonville, Fla., said during a presentation Sept. 10 at the annual scientific sessions of the American Society of Nuclear Cardiology (ASNC). However, cardiac CT may be beneficial in some instances for this patient population when the right methods are used.
