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 کامل201Tl chloride single photon emission computed tomography in patients with oral cavity squamous cell carcinoma
IN SQUAMOUS CELL CARCINOMA (SCC), some authors have reported that tumor angiogenesis is a prognostic factor in predicting the effect of treatment.1,2 There are some studies using microvessel density (MVD) in evaluating angiogenesis and showing the usefulness of MVD in predicting radiosensitivity in esophageal cancer,3 cervix carcinoma,4 and head and neck carcinoma.5–8 Furthermore, some authors ...
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 کاملCharacterization of cartilaginous tumors with 201Tl scintigraphy.
UNLABELLED Histological diagnosis and grading of cartilaginous tumors are closely correlated with patient prognosis; consequently, they are essential elements. We attempted to clarify the characteristics of 201Tl uptake in various histological types of cartilaginous tumors and to assess its clinical value. METHODS Twenty-two cases with histologically proven cartilaginous tumors (3 enchondroma...
متن کاملDiaphyseal medullary stenosis with pleomorphic malignant fibrous histiocytoma of the bone: 99mTc hydroxymethylenediphosphonate and 201Tl chloride scintigraphy findings.
Diaphyseal medullary stenosis (DMS) is an extremely rare hereditary bone dysplasia, which was first described by Arnold in 1973. DMS has a high incidence of pleomorphic malignant fibrous histiocytoma (MFH). In this paper, we report the imaging findings of DMS with pleomorphic MFH of the bone, mainly describing 99mTc hydroxymethylenediphosphonate (HMDP) and thallium-201 (201Tl) chloride scintigr...
