The practice of MPI with SPECT is prevalent in clinical use. However, it is associated with a widely adopted in clinical practice but is associated with a rather high radiation dose.
In a recent study, 24 patients underwent clinically indicated stress MPI using CZT SPECT with a specific tracer dose. Images were reconstructed at different intervals and analyzed and scored by experienced nuclear medicine physicians. These physicians did not know the patients or scan time.
