In the medical field, Tl (radioactive half-life 73 h) is used for diagnostic purposes in the heart and circulatory system, as well as for nuclear imaging of bone tumors (thallium scintigraphy) (Sumiya et al. 2001). [Pg.1101]

Exercise tolerance (stress) testing (ETT) is recommended for patients with an intermediate probability of CAD. Results correlate well with the likelihood of progressing to angina, occurrence of acute MI, and cardiovascular death. Ischemic ST-segment depression during ETT is an independent risk factor for cardiovascular events and mortality. Thallium myocardial perfusion scintigraphy may be used in conjunction with ETT to detect reversible and irreversible defects in blood flow to the myocardium. [Pg.146]

No adverse reactions normally occur in patients taking beta blockers who undergo dipyridamole-thallium-201 scintigraphy and echocardiography, but case reports suggest that very rarely bradycardia and asystole can occur. [Pg.702]

Caffeine (in tea, coffee, cola, etc.) may interfere with dipyrida-mole-thallium-201 scintigraphy tests. Similarly, theophylline can also reduce some of the effects of dipyridamole. [Pg.703]

Caffeine 4 mg/kg intravenously (roughly equivalent to 2 to 3 cups of coffee), given before dipyridamole-thallium-201 myocardial scintigraphy, caused a false-negative test result in a patient. A further study in 8 healthy subjects confirmed that caffeine inhibits the haemodynamic response to an infusion of dipyridamole. Similarly, oral theophylline markedly reduced the diagnostic accuracy of myocardial imaging using dipyridamole. In addition, intravenous aminophylline accelerated the myocardial washout rate of thallium-201 after a dipyridamole infusion. ... [Pg.703]

Both thallium 203 and 20S (70.5%) have a nuclear spin and nuclear magnetic resonance signals are detectable for these isotopes. Radioactive ° T1 is used extensively as an imaging agent in myocardial scintigraphy. [Pg.602]

With electromagnetic flowmetry and Doppler ultrasound (55) it is possible to confirm and quantitate patient complaints, follow the disease progression, and document improvement following pharmacotherapy, exercise therapy, percutaneous endovascular interventions or arterial reconstructive interventions. Limb scintigraphy with thallium-201 presents advantages and great potential for clinical applications (56). [Pg.10]
