Webb27 jan. 2016 · Transient ischemic dilation of the left ventricle may be suggestive of global myocardial ischemia on SPECT stress imaging. While SPECT stress/rest imaging relies on computation-adjusted volumetric data to calculate a stress/rest "TID ratio," measured at 20 to 30 minutes after peak regadenoson stress, cardiac MRI (CMR) allows for the direct …

Webb1 juli 2024 · Introduction. Transient ischemic dilation (TID) of the left ventricle has been considered to be a specific marker of severe and extensive coronary artery disease (CAD).[1,2,3] Initial studies, with the use of exercise thallium-201, noted that the size of the left ventricle is sometime larger on the immediate poststress image than on the 4 h … WebbElevated lung-heart ratio (LHR) and transient ischemic dilation (TID) have been identified as markers of severe coronary artery disease after both exercise and pharmacologic stress testing. We have previously demonstrated a very weak correlation between elevated LHR and TID after exercise, which suggests that they reflect different pathophysiologic …
Webb25 dec. 2009 · These standard software packages obtain several functional parameters, one of which is the transient ischemic dilation (TID) ratio. Although the TID was already described by Slutsky et al4 half way the twentieth century, Stolzenberg popularized the index in 1980 by describing TID in myocardial perfusion images ...
