Low Dose One-Day Tc99m Protocol With a High-Efficiency Cardiac Dedicated Gamma Camera For Detection of Coronary Disease

"The study is designed to assess the validity of a low dose (\~5mSv) Tc99m one day protocol using D-SPECT standard protocol as the comparators.~D-SPECT cardiac scanner the D-SPECT system uses a solid-state detector, made of an alloy of Cadmium, Zinc, and Telluride, eliminating the need for thick crystals and large photomultiplier tubes. As a result, the system is significantly miniaturized, and ergonomically optimized to both user and patient"
