Excerpt
Over the last decades, semi-quantitative analysis has become crucial in the assessment of myocardial perfusion scintigraphy. Through widely available software packages, electrocardiographically (ECG) gated myocardial perfusion single-photon emission computed tomography (SPECT) quantitative parameters of left ventricular (LV) function are easily obtainable. These software algorithms have increased worldwide consistency and improved quality of myocardial perfusion scintigraphy in the assessment of the total ischemic burden, left ventricular (LV) volumes, and left ventricular ejection fraction (LVEF). In general, these software algorithms have standardized the interpretation of ECG gated myocardial perfusion SPECT. However, for other parameters of left ventricular function such as phase analysis of ECG gated myocardial perfusion SPECT and regional analysis of cardiac sympathetic imaging with 123I-meta-iodobenzylguanidine (123I-mIBG), standardization is still not reached. This lack of standardization hampers the widespread clinical use of the potentially very valuable parameters obtained with phase analysis and 123I-mIBG quantitation methods. …
