PET MBF versus Myocardial T 2 in Healthy Canines. Representative short-axis PET images of myocardial blood flow and myocardial T2 maps at rest and stress are shown in panel A. Both BOLD and PET images demonstrate significant signal elevation during stress compared to rest. Rest and stress Mean myocardial blood flow and Myocardial T2 from matched slices are compared in panel B and C, respectively. An average of 2.5 fold increase of myocardial blood flow during stress is observed (panel B) along with a 15% T2 elevation presented in panel C.
