Thallium

06/01/1991 - "By using arteriography as the gold standard for comparison, it appears that thallium scintigraphy has a significantly higher sensitivity but lower specificity for the detection of coronary artery disease than does echocardiography. "
07/01/1986 - "However, because all myocardial segments in a given heart are exposed to the same noncardiac factors, a relative difference in myocardial clearance of thallium between segments could reflect the presence of coronary artery disease. "
02/01/1985 - "Gated thallium tomography--potential for improved accuracy in the detection of coronary artery disease."
01/01/1989 - "Improved detection of coronary artery disease by estimated myocardial thallium uptake."
11/01/1987 - "Gated thallium scintigraphy in patients with coronary artery disease: an improved planar imaging technique."

12/01/1989 - "In patients without previous myocardial infarction, the cardiac event rate was significantly greater in those with an abnormal versus normal thallium scan (55% versus 12%, p less than 0.001). "
01/01/1998 - "In patients with myocardial infarction, of the 36 fixed severe defects, 9 (25%) had improved thallium uptake shortly after reinjection, increasing activity from 36 +/- 10% to 53 +/- 8%, and 22 (61%) defects improved at 24 hours, increasing activity from 37 +/- 8% to 56 +/- 6%. "
12/01/1989 - "Thus, we conclude that thallium re-injection is an improved technique for assessing myocardial viability in patients after myocardial infarction."
11/01/1980 - "Ventricular and coronary angiography and exercise Thallium 201 myocardial scintigraphy allowed the diagnosis of myocardial infarction to be eliminated. "
01/01/2002 - "This study compared the results of tetrofosmin, thallium, and sestamibi single photon emission computed tomography at rest in detection of myocardial viability in patients with previous myocardial infarction. "

12/01/1982 - "This method might be most useful in the treatment of thallium poisoning if its deleterious effects could be eliminated."
06/01/1998 - "In a 27-year old male with acute thallium poisoning, signs of initially severe sensorimotor neuropathy with complete remission after two weeks were demonstrated. "
05/01/2014 - "Blood purification therapies help in the clearance of thallium in those with acute thallium poisoning. "
05/01/2014 - "However, there are few studies about these treatments for acute thallium poisoning. "
05/01/2014 - "Study on the treatment of acute thallium poisoning."

07/01/1987 - "Improved cardiac functional status after sustained successful PTCA was demonstrated by the normal exercise capacity on bicycle exercise testing and the absence of ischemia on thallium 201 scintigraphy studies in 70% of the patients. "
07/01/1989 - "After PTCA, the parameters of residual ischemia in the infarct area (% RD and Thallium ischemic score = TIS) were improved significantly but those of infarct size (RD% uptake and Defect Score = DS) were improved slightly in group A. "
09/14/1984 - "Significant differences between the two groups included improved aerobic capacity, thallium ischemia scores, and ventricular function in the exercise intervention group. "
10/01/1993 - "Teboroxime allows for improved detection of reversible perfusion defects compared with stress/redistribution thallium scanning, but more ischemia is noted with thallium reinjection. "
01/01/1990 - "At each exercise protocol, thallium improved the sensitivity of exercise in detecting ischemia in the noninfarct zone. "

07/01/2003 - "Most of the patients studied (37/50) showed improved myocardial performance during the last of the sequential exercise tests, as demonstrated with the studied exercise parameters and the extent of myocardial ischemia in thallium-scintigraphy. "
01/01/1994 - "In the diagnosis of myocardial ischemia, group C, the Thallium 201 has been very useful and specific excluding an ischemic origin in 4 patients with arrhythmias, in 2 patients without symptoms of angina but with doubts at rest and exercise ECG findings and in 4 with atypical thoracoalgia and doubtful ECG. "
01/01/2001 - "Thus, EECP treatment improves exercise tolerance and reduced myocardial ischemia by thallium scintigraphy in association with improved LV diastolic filling in patients with stable CAD."
04/01/2003 - "Nuclear Cardiology procedures, such as perfusion studies performed with thallium or 99mTc labeled agents (sestamibi, tetrofosmin), radioventriculography for right and left ventricle function evaluation and Gated SPECT are considered the best non-invasive procedures not only for the diagnosis of myocardial ischemia but for risk stratification. "
12/01/2002 - "There was no observable reversible myocardial ischemia on the postoperative thallium single-photon emission computed tomography study. "
