Webwith or without the additional reinjection of 1.0 mCi (37 MBq) of thallium. If reinjection of 1.0 mCi of thallium is planned prior to redistribution imaging, the administered activity used for stress imaging may be limited to 3 mCi. When assessing myocardial viability, additional information may be gained by obtaining 24-hour delayed images. 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.
