Covid-19 manifestation on Tl-201 myocardial perfusion SPECT/CT
A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...
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 myocardial imaging before and after coronary revascularization: assessment of regional myocardial blood flow and graft patency.
Twenty patients underwent myocardial imaging with Thallium-201 (201Tl) before and subsequent to coronary artery bypass grafting. All patients had rest and maximal treadmill exercise imaging postoperatively. Eleven of the 20 patients had rest and exercise 201Tl images preoperatively; 9/20 only had rest imaging preoperatively. Postoperative regional exercise perfusion was improved in seven of the...
متن کاملSerum caffeine levels after 24-hour abstention: clinical implications on dipyridamole (201)Tl myocardial perfusion imaging.
BACKGROUND Caffeine binds to the A2 receptors and inhibits adenosine's action of vasodilation or dipyridamole-induced vasodilation. Patients scheduled for (201)Tl myocardial perfusion using pharmacologic stress with dipyridamole or adenosine are advised to abstain from caffeine for 24 h before the test. This article reports on the residual serum caffeine levels of 36 patients after 24-h caffein...
متن کاملVisual and semi-quantitative assessment of brain tumors using (201)Tl-SPECT.
OBJECTIVE To evaluate the usefulness of (201)Tl-SPECT in differentiating benign from malignant brain tumors. METHODS AND MATERIALS Eighty-eight patients (44 males and 44 females) with 58 high-grade (WHO grade III-IV) and 30 low-grade (WHO grade I-II) tumors were evaluated with (201)Tl-SPECT. (1) Visual assessment was performed by board-certificated radiologists using (201)Tl-SPECT. Tumors wer...
