Abstract 2951: Estimation of Perfusion with
13
N-Ammonia Retention Underestimates the Frequency and Extent of Hibernating Myocardium when Compared to Quantification of Absolute Myocardial Blood Flow
Abstract:Background:
Viable dysfunctional myocardium can be classified as chronically stunned (normal resting perfusion) or hibernating (reduced resting flow). While
13
N-ammonia (NH
3
) retention (late uptake) is typically used to estimate perfusion, the frequency and extent of hibernating myocardium (HM) may differ when quantification of dynamically-acquired absolute myocardial blood flow (MBF) is performed.
