Thallium Stress Test: What to Expect and Understanding
The thallium stress test is an imaging study that shows your doctor how well blood flows to your heart It measures your blood flow during rest and after exercise The thallium The goal of this study was to determine the prognostic utility of the exercise thallium201 stress test in ambulatory patients with chest pain who were also referred for cardiac catheterization Accordingly, 4 to 8 year (mean +/ 1SD, 46 +/ 26 years) followup data were obtained for all but one o Prognostic utility of the exercise thallium201 test in PubMed

Thallium Stress Test: Purpose, Procedure, and Risks Healthline
A thallium stress test is an imaging test that indicates how well blood flows into your heart while you’re exercising or at rest It’s also called a nuclear stress test During the procedureTransient dilatation of the left ventricular cavity on exercise thallium perfusion imaging is recognized as a marker of significant coronary disease, but the mechanisms that produce this finding are not fully understood We studied 32 patients who underwent exercise thallium imaging and exercise echocardiography to determine the changes in left Exercise Echocardiographic Correlates of Transient Dilatation of
Myocardial hibernation identified by hyperbaric oxygen treatment
Myocardial hibernation identified by hyperbaric oxygen treatment and echocardiography in postinfarction patients: Comparison with exercise thallium scintigraphy To evaluate the potential for hyperbaric oxygen (HBO) to produce transient improvement in function in areas of myocardium ischemic at rest (hibernating myocardium), 24 patients @article{Lakkis1995ExerciseTS, title={Exercise thallium201 single photon emission computed tomography for evaluation of coronary artery bypass graft patency}, author={Nasser Lakkis and John J Mahmarian and Mario S Verani}, journal={The American journal of cardiology}, year={1995}, volume={76 3}, pages=Exercise thallium201 single photon emission computed

The aim of the study was to test the diagnostic and prognostic accuracies of combined dipyridamoleexercise thallium imaging in dialysis patients Methods: Dipyridamoleexercise thallium imaging and coronary angiography were both performed prospectively in 60 asymptomatic hemodialysis patients who were followed up, long term, by recording Normal exercise thallium 201 images identify patients at a low risk for future cardiac events (08% per year), patients with abnormal exercise ECGs but normal thallium images have good prognoses, and exercise thallium 201 imaging is a better prognostic predictor than treadmill exercise testing alone, because of the high incidence of inconclusive exercise Prognostic implications of normal exercise thallium 201 images
Best detection of coronary artery disease using a new generation
In contrast, 11 patients who had reversible thallium scan defects showed a consistent decrease in EF (from 53 +/ 2% at rest to 43 +/ 2% during exercise, p less than 0001); 20 patients withTwo methods were used to assess the prognostic value of thallium, imaging: (1) comparison of the prevalence of coronary events in the two groups with normal or abnormal thallium uptake by chisquare test, and calculation of positive and negative predictive values of thallium imaging for predicting future coronary events; (2) Diagnostic accuracy and prognostic value of combined
Importance of Estimated Functional Capacity as a
Exercise thallium testing is often performed to aid the diagnosis, prognosis and functional evaluation of patients with known or suspected coronary artery disease It has been suggested that radionuclide imaging provides little additional diagnostic or prognostic information for patients with severe coronary disease and normal rest ECGs [48]Exercise electrocardiograms were unequivocally abnormal in 24 patients (52%) Qualitative planar thallium images were abnormal in 42 patients (91%) Quantitative analysis of the tomographic thallium images were abnormal in 41 patients (89%) An exercise ejection fraction of less than 056 or a new wall motion abnormality was seen in 30 patientsAssessment of single vessel coronary artery disease: results of
Thallium201 myocardial perfusion imaging at rest and during exercise
The sensitivity of myocardial perfusion imaging (MPI) using thallium201 injected both at rest and during peak exercise was compared to simultaneously recorded 12 lead electrocardiography However, when chest pain and/or ST depression were considered indices of ischemia, the sensitivity of exercise testing and thallium201 MPI was similarExercise TwoDimensional Echocardiography Twodimensional echocardiography was performed at rest (prior to exercise) and immediately upon termination of exercise (prior to thallium imaging) in accordance with previously described techniques 10 Four standard views were obtained Echocardiograms were recorded Exercise Echocardiographic Correlates of Transient Dilatation
Thallium 201 for assessment of myocardial viability
In approx imately 10% of thallium defects that develop during exercise, redistribution occurs by 4 hours, but reinjection then results in apparent thallium "washout," a process the authors have termed "differential uptake" of thallium41'47 This phe nomenon results from proportionately higher uptake of thallium after reinjection in Coronary flow reserve, exercise thallium201 scintigraphy and exercise radionuclide ventriculography were compared in 18 patients with chest pain and angiographically normal coronary arteries Regional exercise thallium201 perfusion was abnormal in three patients, regional exercise wall motion was Abnormal coronary flow reserve and abnormal radionuclide exercise
