OBJECTIVE The prognostic values of serum thyroglobulin (Tg) and antithyroglobulin antibody (TgAb) levels, measured immediately before I-131remnant ablation in patients with differentiated thyroid cancer (DTC), have been advocated by some researchers; however, it had controversial outcomes. This study was carried out to examine this dilemma and to check the clinical significance of basal serum T...
For imaging of dopamine D2/3 receptors, agonist tracers are favoured over antagonists because they are more sensitive to detection of dopamine release and because they may selectively label the high-affinity receptor state. We have developed novel D2/3 receptor selective agonists that can be radiolabelled with [(123)I], which label is advantageous over most other labels, such as carbon-11, as i...
The high affinity translocator protein (TSPO) ligand 6-chloro-2-(4'-iodophenyl)-3-(N,N-methylethyl)imidazo[1,2-a]pyridine-3-acetamide (CLINME) was radiolabelled with iodine-123 and assessed for its sensitivity for the TSPO in rodents. Moreover neuroinflammatory changes on a unilateral excitotoxic lesion rat model were detected using SPECT imaging. [(123)I]-CLINME was prepared in 70-80% radioche...
OBJECTIVE To investigate whether a serotonin-to-dopamine terminal ratio is related to the appearance of dyskinesias in patients with Parkinson disease (PD). METHODS Twenty-eight patients with idiopathic PD (17 with levodopa-induced dyskinesias [LIDs], 11 without dyskinesias) and 12 age-matched healthy controls were studied with PET and 5[(11)C]-3-amino-4-(2-dimethylaminomethylphenyl-sulfanyl)...
introduction: high-dose radioactive iodine therapy in differentiated thyroid cancer (dtc) may adversely affect the salivary gland function. this study is aimed to evaluate the effect of radioactive iodine (rai) with dose of 100 mci in dtc patients compared to lower doses of less than 30 mci in hyperthyroid cases. methods: fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...
RADIOACTIVE iodine (iodine-131) has been used extensively during the past 30 years for the treatment of hyperthyroidism and has been shown to control this disorder in the majority of cases in which it has been used. There have been varying reports of the incidence of post-radiation hypothyroidism which has been reported to be as high as 70 per cent in patients followed up for 10 years (Beling a...
UNLABELLED Our group has developed a new radiopharmaceutical, (123)I - N-(2-diethylaminoethyl)-2-iodobenzamide ((123)I-BZA2), a benzamide derivative able to bind to melanin pigment in melanoma cells. In a prospective and multicentric phase III clinical study, the value of (18)F-FDG PET/CT and (123)I-BZA2 scintigraphy was compared for melanoma staging. METHODS Patients with a past history of c...
