Cardiac Pinhole-Gated SPECT in Small Animals.

Electrocardiographically gated myocardial perfusion single-photon emission computed tomography (gated-SPECT)is a non-invasive and valuable tool for simultaneous assessment of myocardial perfusion and cardiac function in man. The use of this technique in rats is challenging because of the small size of the heart and the heart rate. [ABSTRACT FROM AUTHOR]
