摘要:
This invention relates to a method of predicting the activity of a CNS drug on striatal dopamine transporter populations. The method uses SPECT brain imaging to predict the activity of antidepressants or anxiolytic agents on striatal dopamine transporter populations. The method uses the increase in dopamine transporter populations as a marker for predicting sexual dysfunction side effects, as well as to determine proper dosing for antidepressants or anxiolytics agents in order to avoid the sexual dysfunction side effects.

This invention provides novel radiopharmaceuticals which are useful as imaging agents for the diagnosis of cardiovascular disorders, infectious disease and cancer. The radiopharmaceuticals are comprised of phosphine or arsine ligated technetium-99m labeled hydrazino or diazino modified biologically active molecules that selectively localize at sites of disease and thus allow an image to be obtained of the loci using gamma scintigraphy. This invention also provides methods for using the radiopharmaceuticals and kits comprising radiopharmaceutical precursors. The radiopharmaceuticals of this invention have the structure:[(Q).sub.d 'L.sub.n -C.sub.h '].sub.x -M.sub.t (A.sub.L1).sub.y (A.sub.L2)z;wherein the variables are as defined herein.
摘要:
A nuclear medicine technique for detecting and localizing carcinomas in the breasts of patients with dense breast. In the method, a patient with dense breast is administering a dose of Technetium-99m Sestamibi, or another nuclear medicine substance which selectively accumulates in breast carcinomas. The breast is then imaged with a nuclear medicine detector to image the carcinomas with the accumulated nuclear medicine agent and localize the carcinomas in real time and in three dimensions. The imaging can be done in a first plane with the detector perpendicular to a lateral side of the breast and also in a second plane parallel to the patient's chest wall.

摘要:
Process for the preparation of nitride complexes of transition metals for use as radiopharmaceutical products or for the synthesis of novel pharmaceutical products. The process consists in reacting an oxygenic transition metal compound such as 99m.sub.Tc, 186.sub.Re or 188.sub.Re, with a first nitrogenous ligand such as sodium nitride or a nitrogenous compound such as S-methyl, N-methyl dithiocarbazate, and a reducing agent consisting of either tin (II) or a dithionite. The product so obtained can be used for the preparation of radiopharmaceutical products by a reaction with a second ligand such as sodium dithiocarbamate.
