Thallium-201/Nasal administration/Biological safety/Preclinical study. Nasal administration of thallium-201 (Tl) has previously been shown to be useful for the assessment of olfactory nerve connectivity in vivo. We assessed the biological effects of nasal Tl administration in mice to determine its safety before conducting clinical trials on humans. Tl uptake was evaluated in normal mice (n = 5)...
Thallium-201 chloride ((201)TlCl) is frequently used for imaging of a variety of malignant tumors viz., thyroid, lung, brain, bone and breast, however in patients with colorectal cancer, its role is not well established. In this case report we present three patients with colorectal cancer recurrence, with inconclusive computed tomography (CT) findings while (201)TlCl single photon emission tomo...

introduction: meningioma is usually a benign brain tumor, but sometimes with aggressive course. the aim of this study was to assess the ability of 201tl brain spect to differentiate the pathologic grade of meningioma preoperatively. methods: thirty lesions in 28 patients were evaluated in this study. early (20 minutes) and late (3 hours) brain spect images were performed and early uptake ratio...
OBJECTIVES We sought to study the accuracy of exercise perfusion scintigraphy in patients with an implanted apical right ventricular pacemaker. BACKGROUND The specificity of exercise perfusion scintigraphy is decreased in patients with a left bundle branch block. Patients with a permanent ventricular pacemaker have a similar conduction abnormality that may also potentially result in similar f...
