Tid ratio stress
Webbstudy, we calculated and compared TID ratios for CT-AC and non-attenuation correction (NAC) acquisitions for different sets of stress modalities and software packages in the low pre-test probability group. We also evaluated the impact of gender and software programs on the calculated TID ratios. Webb31 juli 2015 · TID ratios derived from hearts less than 20 ml (i.e., small hearts) were excluded from analysis. Both stress and rest left ventricular EF ratios (EF ratio) and differences (EF change), retrieved from the QGS algorithm, were calculated as manifestations of post-stress EF changes.
