Does twenty-four hour delayed imaging following thallium reinjection enhance detection of viable myocardium?

Thallium 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...

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.

Viable myocardium and reinjection of thallium.

Thallium 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...

Dose Nitroglycerine enhance detection of viable myocardium by Tl-201 SPECT? [Persian]

It is suggested that sublingual nitroglycerine can improve the ability of T1-201 for detection of viable myocardium. Methods and Results: In a randomized, double blind study, 50 patients who had fixed defects on stress-redistribution scan, were randomized into two groups. In group I, patients received 0.4-0.8 mg sublingual nitroglycerine, before T1-201 reinjection. In group II, reinjectio...
