Clinical Evaluation of Thyroid Imaging with 201Tl-Chloride
Clinical value and limitation of thyroid imaging with 201T1C1 were studied. The positive rate of 201T1 was 82% in 22 malignant thyroid lesions and 46% in 37 benign lesions. A 201T1 positive image was obtained when a lesion was parenchymatous and a 201T1 negative one when it was cystic, filled with colloid or hyaline and had massive necrosis or bleeding. Thus 201T1 Cl localized in a parenchymato...
متن کاملMyocardial perfusion imaging with 201Tl.
The object of this review is to provide information about (201)Tl-thallous chloride in radionuclide myocardial perfusion imaging. This technique has experienced a recent resurgence because of the shortage of (99m)Tc. After reading this article, the technologist will be able to describe the properties and uptake mechanism of (201)Tl, the procedure for myocardial perfusion imaging with this agent...
متن کاملOptimized energy window configuration for 201Tl imaging.
UNLABELLED A poor signal-to-noise ratio attributable to a low injected dose of thallium and the presence of scattered photons are the major impediments in the use of thallium as an imaging agent. Thallium decays in a complicated way and emits photons in a wide range of energies (68-82 keV). To increase the ratios of primary photons to scatter photons (primary-to-scatter ratios) and possibly inc...
متن کاملPercutaneous microwave ablation of thyroid nodules: efficacy evaluation with 99m Tc - pertechnetate and 99mTc-MIBI functional imaging
Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...
