Kit for preparing Tc (III)-99m myocardial imaging agents that are effective in humans

摘要

A myocardial imaging agent for humans is a technetium(III) complex ligated in the planar positions by a tetradentate ligand such as (acac)2en and in the axial positions by an ether containing phosphine ligand such as tris(3-methoxy-1-propyl)-phosphine. The agent exhibits extremely rapid blood clearance after injection into a human and has a sufficiently high heart/liver and heart/lung ratios to provide effecitve myocardial images. A kit for preparing the above myocardial agent is disclosed.
