No Difference Between SPECT Camera Systems for Myocardial Blood Flow

This paper attempted to quantify myocardial blood flow using two different SPECT camera systems: rapid-rotating gantry (RRG) and cadmium-zinc-telluride (CZT). The authors enrolled 20 patients with congestive heart failure and 20 patients without congestive heart failure. SPECT imaging was performed on two consecutive days using the two systems. The results suggested no significant differences between resting myocardial blood flow values. In patients with congestive heart failure. “Physical corrections along with other image corrections can provide comparable myocardial blood flow quantitations in both CHF and non-CHF patients, regardless of the type of SPECT systems used,” the researchers wrote.
