Thallium-201 myocardial imaging to evaluate right ventricular overloading.
The usefulness of thallium-201 myocardial imaging in assessing right ventricular (RV) overloading was evaluated and compared with the electrocardiographic and hemodynamic measurements. Multiple unprocessed photoscans were obtained using a gamma camera in 47 patients who had chronic RV overload, including 28 subjects with pressure overload, 14 with volume overload and five with pressure and volu...

متن کاملThallium-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...
