In every patient, Quantitative Gated SPECT and Quantitative Perfusion SPECT programs were used both at rest and after stress after qualitative analysis of reconstructed images. In 6% of patients (mainly those with low EF and dominance of myocardial necrosis), LV contours were manually adjusted. Exercise-induced angina produces defects in stress perfusion images and is associated with LV contractile dysfunction. In most patients, these abnormalities quickly return to baseline (reversible) after cessation of the exercise.Quality assurance images demonstrated moderate motion during acquisition with a mild male pattern of inferior attenuation. Image analysis showed a fixed inferior count reduction, which improved with attenuation correction.
This article provides basic information concerning the interpretation of gated SPECT imaging, including such parameters as left ventricular wall motion and thickening as well as left ventricular wall systolic and diastolic function. The gated SPECT determination of the left ventricular ejection fraction and volumes has been extensively validated. Additionally, this method allows for the improved identification of soft-tissue artifacts and enhances the detection of multivessel coronary artery disease. The transformation to SPECT with these imaging agents permitted gating of images and calculation of left ventricular ejection fraction (LVEF) and end-systolic and end-diastolic volumes and quantitation of regional wall motion or thickening abnormality extent.
This method is unique in providing simultaneous bi-modal functional imaging of relative myocardial perfusion and left ventricular (LV) function. 1 While perfusion images identify regions with relative hypoperfusion, gated SPECT allows assessment of global and regional LV function.Betesti et al.5 demonstrated that post-stress LV dilation by gated SPECT reflected endocardial post-is-chemic stunning with reduced ejection fraction and thickening score, and was associated with more severe clinical, angiographic, and perfusion parameters.We recently presented CAFU, a new method for quantification of left ventricular (LV) volumes and ejection fraction (EF) from myocardial perfusion, gated single photon emission computed tomography (SPECT) images (Lomsky et al., 2005).gated myocardial perfusion SPECT (GSPECT) has been increasingly used for the assessment of the LV function in the clinical setting. ECG gating of a standard myocardial perfusion SPECT acquisition allows for the quantitative or semiquantitative assessment of the LV function simulta-neously with the evaluation of the LV perfusion (1).
