Recently introduced high-efficiency (HE) SPECT cameras with solid-state CZT detectors
have been shown to decrease imaging time and reduce radiation exposure to patients.
An automated, computer-derived quantification of HE MPI has been shown to correlate
well with coronary angiography on one HE SPECT camera system (D-SPECT), but has not
been compared to visual interpretation on any of the HE SPECT platforms.
