Thallium-201 Myocardial Perfusion Imaging
The sensitivity of myocardial perfusion imaging (MPI) using thallium-201 injected both at rest and during peak exercise was compared to simultaneously recorded 12 lead electrocardiography (ECG) for the detection of transient ischemia in 20 normal subjects and 63 patients with coronary artery disease (CAD). No significant perfusion defects or ECG changes were seen on either the rest or exercise ...
متن کاملSerial Myocardial Imaging after a Single Dose of Thallium-201
Although thallium-201 exercise scintigraphy has been established for the detection of myocardial ischemia and viability, little is known regarding the myocardial thallium-201 kinetics during angioplasty. Herein, we report a 77-year old man with angina pectoris, in whom serial myocardial imaging after a single dose of thallium-201 was helpful in identifying not only the culprit lesion and myocar...
متن کاملThallium-201 for myocardial imaging. Relation of thallium-201 to regional myocardial perfusion.
Following intravenous administration, the myocardial concentration of tracer thallium-201, potassium-43, and rubidium-81 were determined in mice; thallium was present in the greatest concentration in the myocardium (2.08% compared 1.25% for potassium and 1.15% for rubidium at 10 minutes). The regional myocardial distribution of thallium-201 was determined in dogs under conditions of normal flow...
متن کاملEvaluation of myocardial involvement in Duchenne's progressive muscular dystrophy with thallium-201 myocardial perfusion imaging.
Myocardial involvement in progressive muscular dystrophy of the Duchenne type was evaluated in 19 patients using thallium-201 myocardial perfusion imaging. A qualitative analysis was performed from five projection images by three experienced physicians. Distinct perfusion defects were shown in 13 patients, especially in the LV posterolateral or posterior wall (11 patients). There was no signifi...
متن کاملResurrection of thallium-201 for myocardial perfusion imaging.
a D t t H w l c T t l t a e 9 2 r t c A i “ e 9 n a s t s r m m p i Thallium-201 has several virtues as a myocardial perfusion agent. It is one of the best of the soluble agents for measuring regional myocardial perfusion, because it has a blood clearance half-time of 30 s and a first pass extraction in the myocardium of 88% (1) (compared with the 1-min blood clearance half-time [2] and 50% to ...
