Purpose We compared two methods for measuring myocardial wall thickening from nuclear
medicine perfusion scans. The first method uses the percent change in peak activity, and the …

Background Some single photon emission computed tomography (SPECT) methods to
detect percent myocardial wall thickening (% WT) assume a linear relationship to changes in …

Background Current assessment of regional left ventricular function with electrocardiogram
(ECG)-gated single photon emission computed tomography (SPECT) imaging is generally …

Results: Two patternsof artifactualinhomogeneitywere found: a depression in activity at the
antero-apex and an elevation in activity in the free wall compared with the septum. Thus, in …

Purpose Electrocardiograph-gated myocardial SPECT permits a quantitative assessment of
global and regional functions by quantitative gated SPECT software. To validate quantitative …

This study was performed to clarify the validity of quantification of myocardial wall thickening
by the count increase method using electrocardiography (ECG)-gated SPECT. Methods: We …
