Thallium reinjection versus standard stress/delay redistribution imaging for prediction of cardiac events.
OBJECTIVES The purpose of this study was to compare thallium reinjection with standard stress/delay redistribution for the prediction of cardiac events. BACKGROUND Although thallium reinjection enhances the detection of viable myocardium, its contribution to prognosis over stress/delay redistribution in a general referral population has not been clearly evaluated. METHODS This retrospective...
متن کاملDifferential Uptake and Apparent 20TI Washout After Thallium Reinjection Options Regarding Early Redistribution Imaging Before Reinjection or Late Redistribution Imaging After Reinjection
Background. Because thallium reinjection enhances the identification of viable myocardium, many laboratories have adopted the routine practice of performing reinjection imaging instead of 3-4-hour redistribution imaging. This approach assumes that the stress-reinjection protocol provides the necessary information regarding both exercise-induced ischemia and myocardial viability. Because apparen...
متن کاملThallium reinjection after stress-redistribution imaging. Does 24-hour delayed imaging after reinjection enhance detection of viable myocardium?
BACKGROUND Thallium reinjection immediately after conventional stress-redistribution imaging improves the detection of viable myocardium, as many myocardial regions with apparently "irreversible" thallium defects on standard 3-4-hour redistribution images manifest enhanced thallium uptake after reinjection. Because the 10-minute period between reinjection and imaging may be too short, the prese...

متن کاملThallium reinjection demonstrates viable myocardium in regions with reverse redistribution.
BACKGROUND The clinical significance and pathophysiological mechanisms of reverse redistribution on stress-redistribution thallium-201 myocardial scintigraphy in patients with chronic coronary artery disease are unclear. Recent studies have shown that thallium-201 reinjection is a useful technique for the detection of myocardial viability in chronic coronary artery disease. In this investigatio...
