To assess the clinical significance of 201Tl-SPECT after postoperative radiotherapy in patients with glioblastoma multiforme (GM). Eighteen patients with macroscopically residual GM who underwent 201Tl-SPECT just after postoperative radiotherapy were analyzed. Fifteen patients (83%) received radioth

The NCRP Wound Model, which describes the retention of selected radionuclides at the site of a contaminated wound and their uptake into the transfer compartment, has been combined with the ICRP element-specific systemic models for those radionuclides to derive dose coefficients for intakes via conta

… At the time of the study, 14-Cmethionine (0.74 MBq) and 201Tl (14.8 MBq) were injected intravenously at 20 and 10 min before sacrifice, respectively. … Results: Both 14Cmethionine (uptake ratio, 0.71 ± 0.13) and 201Tl uptake were reduced in the area at risk at 1 d after reperfusion. … However, 3 d after reperfusion, an increased 14-Cmethionine uptake (1.79 ± 0.23) was observed corresponding to the area of still-reduced 201Tl uptake, and the 14-Cmethionine uptake gradually declined until 28 d. …

… Purpose: The aim of this study was to assess whether migration of thallium-201 (201Tl) to the olfactory bulb were reduced in patients with olfactory impairments in comparison to healthy volunteers after nasal administration of 201Tl. … 201Tl olfactory migration was also correlated with the volume of the olfactory bulb determined from MRI images, as well as with odor recognition thresholds measured by using T&T olfactometry. …
