Clinical impact of arrhythmias on gated SPECT cardiac myocardial perfusion and function assessment

Abstract: As with quantitative measurements, thickening is the parameter most prone to error in the presence of arrhythmias. It is important to test data for gating errors to avoid potentially erroneous measurements and visual readings.

“…The almost universal use of gated SPECT for myocardial perfusion imaging has been made possible by the availability of the technetium-labelled perfusion agents, the propagation of multihead gamma cameras, the increased power of computer systems and the development of dedicated software for processing of perfusion and functional data. The presence of very important arrhythmic problems remains the only reason for avoiding acquisition of a perfusion study using electrocardiographic gating [37,41,42]. It must be considered that some major gating artefacts may propagate even to the summed perfusion images and thus affect their reliability [37].…”

“…In these subjects, the summed frames will be usable for perfusion assessment, whilst the gated data may remain valuable for a visual estimate of ventricular function. In the presence of heart rhythm disturbances, the assessment of wall thickening is the most sensitive parameter, while ejection fraction has been demonstrated to be a quite robust measurement [41,42].…”

“…An additional limitation may be the particular focus of this study on perfusion parameters alone. Since gated SPECT wall motion analysis is subjective, 20 we did not include this parameter in our multivariate analysis. Ischemic cardiomyopathy is often characterized by more focal regional abnormalities, 8,14 but significant group overlap (with nonischemic cardiomyopathy) has been reported.…”

“…12 Multiple different approaches are possible in acquiring SPECT data with ECG-gating, and effects of gating errors and arrhythmias on quantified parameters have been reported. 13 By the same token, several different approaches to handle cardiac displacement to account for breathing motion are possible. With these new approaches to incorporate information regarding pulmonary motion, attention now has broadened to assessing the effects of pulmonary gating errors and breathing motion not only on myocardial perfusion but on the other parameters as well.…”
