WebThe perfusion defects in the group with good collaterals were predominantly reversible, suggesting that coronary collaterals preserved myocardial viability in the regions subtended by a total coronary occlusion. A significant correlation between good collaterals with complete protection and poor collaterals with no protection was noted. WebFor viability assessment, the patient can be given a second injection of thallium and reimaged on the following morning; alternatively, thallium can be given the night before imaging begins. Figure 2 is a diagram of dual-isotope imaging protocol options.
