While no difference was found between the original sound and the resulting sound with Dynamic AV-45 PET scans (0-180 min) were performed in seven subjects. quality and the final diagnosis for myocardial perfusion SPECT in Sweden.

Finally, time-of-flight detection (unique to PET) and dual-tracer imaging (still clinically unique to SPECT but might be feasible for PET in the future) are emphasized in the subsequent three sections, respectively, as additional areas of research and development. There are several differences between SPECT and PET to be noted. In general, the severity of hypometabolism seen on PET is greater than the severity of hypoperfusion on SPECT. The nuclear societies data support increased accuracy of PET over SPECT, particularly for heavier patients, where breast, chest wall, and diaphragmatic attenuation interfere with conventional SPECT.

SPECT scans measure gamma rays, and the radiotracers used with PET scans produce small particles called positrons.
