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 pres...

متن کاملRegional thallium uptake in irreversible defects.
Background. Thallium reinjection immediately after stress-redistribution imaging identifies ischemic but viable myocardium in as many as 50%o of the regions characterized by conventional redistribution imaging as irreversibly injured. However, we have previously shown that some regions in which irreversible defects persist despite reinjection are metabolically active, and hence viable, by posit...
متن کاملIntracellular [Ca2+] in normal and diseased human myocardium.
incorrectly interpreted to be irreversible if only stress-reinjection images were acquired. Dr. Freedman's finding of low differential uptake in 11% of their patients after reinjection appears to confirm our results. We agree with Dr. Freedman that similar information might be obtained if an analysis of thallium activity after a resting injection of 20`T1 were used. Preliminary data in our labo...
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...
