“…There was also a high agreement (over 85%) between the A-SPECT and CZT-SPECT cameras in terms of the percentages of abnormal study results, ischemia and permanent perfusion defects. Other authors of studies on smaller groups of patients also demonstrated high agreement between results of studies on both discussed types of cameras [11,12,17,28,29].…”

“…As shown by the two previously mentioned meta-analyzes of the results of CZT-SPECT perfusion studies [14,15], the specificity of those studies in detecting coronary artery disease is lower than their sensitivity (69% and 72% vs. 84% and 84%, respectively). The relatively high rate of false-positive results is attributed, as is the case with conventional cameras, to the attenuation of radiation in the patient body, which is largely related to obesity [17]. In order to improve the quality of studies, attempts are made to correct the attenuation.…”

Capabilities of Modern Semiconductor Gamma Cameras in Radionuclide Diagnosis of Coronary Artery Disease

This paper presents a review of the literature concerning the clinical application of modern semiconductor (CZT) gamma cameras in the radioinuclide diagnosis of coronary artery disease. It contains information on the diagnostic efficacy of myocardial perfusion studies performed with those cameras compared with the widely used scintillation (Anger) cameras, an overview of their effectiveness in comparison with coronary angiography (also fractional flow reserve) and currently available clinical results of a myocardial flow reserve measured with a dynamic SPECT study. Introduction of this imaging modality to the measurement of a myocardial flow reserve aims to facilitate access to this type of study compared to the less available and more expensive PET method used so far.
