Cardiac PET

Cardiac PET Overview​

Cardiac Positron Emission Tomography is emerging as the preferred test for the diagnosis of coronary artery disease (CAD). Despite the clear majority of nuclear cardiology procedures being performed on Single Photon Emission Computed Tomography (SPECT) imaging devices, there are several advantages of PET over SPECT: lower radiation dose to the patient, improved radiopharmaceutical kinetics, well established attenuation correction, coincidence detection of emitted events, and the ability to perform routine accurate coronary blood flow measurements.

These advantages correlate with improvements in procedure accuracy and sensitivity compared to SPECT, particularly for heavier patients, where breast, chest wall, and diaphragmatic attenuation interfere with conventional SPECT.
