Thallium

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. "
07/06/2021 - "To evaluate the efficacy of treatments and outcomes of five patients with early diagnosis of acute thallium poisoning. "
08/11/2022 - "This study provides further insight into the causes of thallium toxicity and may be useful in the development of new treatments for thallium poisoning."
01/01/2021 - "The Sklifosovsky Institute conducted the largest study in Russian Federation investigating disorders in persons with acute thallium poisoning confirmed by laboratory tests. "

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."

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. "
01/01/2000 - "Among 20,097 patients referred for exercise tomographic thallium imaging in a nuclear cardiology laboratory at a tertiary care center, 1,873 patients met inclusion criteria for this study, which included no history of myocardial infarction or coronary artery revascularization, a normal resting ECG, and normal exercise thallium images. "

08/01/1986 - "Because improvement in the stratification of patients is not as clear as expected from studies performed at a later stage, it appears that exercise thallium scintigraphy at a submaximal level one or two weeks after infarction does not provide optimal information. "
02/01/1993 - "These results suggest that the combined use of stress thallium SPECT, gated blood pool planar and SPECT techniques can contribute not only to the assessment of the efficacy of coronary angioplasty but also to detecting the mismatching of myocardial perfusion and contraction ("myocardial hibernation") in infarct-related myocardial lesions."
10/01/1982 - "Reperfusion produced an increase in thallium uptake in the infarct-related myocardium that was accompanied by an improvement in regional function. "
08/01/2005 - "Study included 43 test and 43 control patients and were matched for their age, sex, status of pretest exercise tolerance, area of infarction and for interval between infarction and stress thallium test. "
12/01/1996 - "The primary end point of the Emory Angioplasty versus Surgery Trial was a composite of three events: death, Q-wave infarction, and a new large defect on 3-year postoperative thallium scan. "

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. "
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. "
03/01/1999 - "Among 44 patients with a reversible thallium defect, 19 (43%) reached the study endpoint, compared with only five of 29 patients (17%) without reversible ischemia (P = .04). "
