Infusion versus bolus injection of Tc-99m tetrofosmin in the identification of viable myocardium.
In this report, a patient with 100% RCA stenosis and prominent collaterals, in which TI-201 rest/redistribution and Tc-99m tetrofosmin infusion imaging findings were compatible with viable myocardium in contrast to Tc-99m tetrofosmin bolus imaging is presented. Viability was confirmed with improvement of wall motion and perfusion 3 months after revascularization. Infusion of Tc-99m tetrofosmin rather than a bolus injection may be a more reliable technique in the identification of severely ischemic but viable myocardium.
