12/01/2002 - "The aim of this study was to quantitatively assess myocardial perfusion by harmonic power Doppler imaging in patients with a previous myocardial infarction and compare myocardial contrast echocardiography results with myocardial viability evaluated by thallium-201 single-photon emission computed tomography ((201)Tl-SPECT) and the results of Doppler flow measurement of coronary flow velocity reserve. "

12/01/1982 - "Three months after infarction, although there was a significantly greater rate-pressure product which would predict a larger ischemic defect and a decrease in the stress thallium-201 score, the stress score was improved (48.3 +/- 1.1, p less than 0.001). "

03/10/2005 - "Exercise thallium-201 SPECT was performed 6 months after successful direct angioplasty in 67 male patients (60.6 +/- 11.5 years), who had Q wave infarction resulting from single vessel disease, and the number of perfusion defect areas (DS) was measured at rest and exercise together with QT (QTc) dispersion. "
10/01/2004 - "The infarct size was quantitatively calculated from rest thallium-201 myocardial single photon emission computed tomography. "

07/01/2017 - "To study the efficacy of thallium-201 as tumor seeking agent and to study its role in therapeutic response."
12/07/2016 - "Magnetic resonance imaging (MRI), computed tomography (CT), and thallium-201 scintigraphy studies confirm the presence of soft tissue mass which had continuity with sciatic nerve, with subsequent serial MRI findings suggesting tumor enlargement with cystic degeneration. "
11/01/2011 - "The aim of this study is to evaluate whether thallium-201 (201-Tl) scintigraphy can differentiate malignant from benign soft-tissue tumors. "
08/01/2009 - "Thallium-201 SPECT studies were performed in 79 patients previously treated for glial tumor with clinical or radiologic suspicion of recurrence. "

"
