[Indium-111-DTPA-phenyl-pentetreotide somatostatin receptors' scintigraphy in the evaluation of patients with suspected gastro-entero-pancreatic tumors. Comparison with computerized tomography].

Gastro-entero-pancreatic tumors (GEP) contain, in their majority, somatostatin receptors. In-111-DTPA-phenyl-pentetreotide has been proved to have high affinity for somatostatin receptors subtypes 2, 3 and 5. The aim of the present study was to evaluate the utility of (111)In-DTPA-O somatostatin receptors' scintigraphy (SRS) in the diagnosis of suspected GEP.

Oprimizing the protocol for the calculation of the doses of (131)I administered for the treatment of benign thyroid disease.

The administration of (131)I for the treatment of benign thyroid disease is widely used in clinical practice. The appropriate dose of (131)I, so as the gland could receive the specified absorbed dose, is determined by various methods. The mostly used is the one based on the 24 h uptake.

[The clinical and laboratory findings in Graves' multinodular type disease].

Graves' disease (GD) is an autoimmune thyroid disease characterized among other findings by diffuse goiter. It is possible in GD to find a multinodular goiter (mGD). Are they two different diseases that coexist, or do we have a multinodular type of GD.

[Findings from molecular imaging with SPET camera and 123I-ioflupane in the differential diagnosis of Parkinsonism and essential tremor].

The aim of the present study was to evaluate the use of the radiopharmaceutical 123I-ioflupane in the diagnosis and differential diagnosis of Parkinsonism (P) and essential tremor (ET). Forty-three consecutive patients, aged 35-72 years, presenting symptoms and signs compatible with P, plus 11 normal volunteers, aged 40-60 years, were enrolled for the study. The radiopharmaceutical was injected iv in a dose of 185 MBq and tomographic acquisition in a single-headed Pegasys gamma-camera (ADAC, USA), 3-4 hours post injection was performed in order to evaluate the activity of the presynaptic nigro-striatal dopaminergic transporter.
