Summary

The new cadmium-zinc-telluride (CZT) technology is a powerful tool for cardiac nuclear medicine. The increased photon counting sensitivity of camera can be used to explore novel protocols like dual isotope (rapid stress Tl-201/rest Tc-99m protocol for use with high-speed SPECT MPI). The use of dual isotope imaging is very interesting because this imaging combines the use of thallium-201 with technetium-99m agents permitting optimal image resolution and simultaneous assessment of viability, all with an exam duration of approximately 20 minutes. However, no study compares stress thallium-201/rest technetium-99m sequential dual isotope high-speed myocardial perfusion imaging versus invasive coronary angiography. The investigators report here the first validation of high-speed protocol with dual isotope for myocardial perfusion imaging using invasive coronary angiography as the standard of reference.

PROCEDURE

coronary angiography

A 6 French arterial sheath was introduced into the radial artery. After administration of 5000 U heparin, the guiding catheter was advanced into the coronary ostium. Intracoronary nitroglycerin 0.2 mg was administered, and reference images were made. Significant CAD was defined as presentation of a stenosis ≥70 % in the three-epicardial vessels and ≥ 50 % in left main coronary disease. If necessary (at the discretion of the practitioner) the pressure wire was advanced across the stenosis, and Fractional flow reserve (FFR) was measured.
