Early redistribution of thallium-201 after temporary ischemia.
To define the time course of redistribution of thallium-201 (201Tl), ischemia was induced in seven pigs by temporary occlusion of the circumflex coronary artery. After 1 1/2 min of occlusion 201Tl and labeled microspheres were injected into the left atrium. Flow was re-established 4 min after occlusion. Prior to reflow, the relative activities of 201Tl and microspheres in the ischemic area were...
متن کاملTime course of thallium-201 redistribution after transient myocardial ischemia.
The mechanism and time course of thallium-201 (201T1) redistribution after transient myocardial ischemia was investigated in 27 anesthetized dogs given 1.5 mCi of 201Tl intravenously 10 minutes after occlusion of the left anterior descending coronary artery. Coronary reperfusion (RP) was accomplished 10 minutes after 2`TI administration. Transmural myocardial biopsies were obtained in situ from...
متن کاملDetection of recurrent thyroid cancer: MR versus thallium-201 scintigraphy.
PURPOSE To compare MR with thallium-201 scintigraphy in the follow-up of patients who have undergone thyroidectomy and modified radical neck dissection for differentiated thyroid cancer. METHODS Both MR imaging and 201Tl scintigraphy were performed in 39 patients after surgery for differentiated thyroid cancer. Ten patients did not have recurrence; 29 patients had 51 recurrent tumors in the n...
متن کاملGliosarcoma with thallium-201 SPECT.
Thallium-201 (201Tl) chloride scintigraphy is the imaging method use for the detection of various tumors including glioblastoma, but only limited information on 201Tl uptake in gliosarcoma is available. We investigated a patient with gliosarcoma by means of 201Tl single-photon emission computed tomography (SPECT) and MRI. SPECT imaging revealed high 201Tl uptake in the tumor, which was closely ...
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 ...
