Overview
To improve the accuracy of myocardial perfusion imaging, it is necessary to acquire the additional study in a changed body position, or to use a CT attenuation correction (AC). AC can be technically easil performed on a hybrid SPECT/CT camera. For AC on SPECT only camera, typically cardiac Cadmium Zinc Telluride (CZT) camera, we can use an external CT. Moreover, even ECG-gated CT coronary artery calcium scoring can be used for AC. The aim of our study is to present our experience with the fusion of SPECT and CT for AC on CZT camera.
