Imaging of a coronary vessel anomaly with aneurysm and arteriovenous fistula by means of MR bolustracking technique

Coronary arteriovenous fistulas are very rare findings and predominantly dr ain into the right atrium or the right ventricle. Echocardiography and x-ra y coronary angiography are established methods in the detection of this ano malies. It is reported on a patient, in whom an anomaly with dilatation of the circumflex coronary artery, aneurysma and drainage over an arteriovenou s fistula in the right ventricle was observed. By means of magnetic resonan ce tomography with bolustracking technique the vessel course and the dynami cs of perfusion are noninvasiv shown beside the imaging using TSE-sequence. The method of multiple injections of 2 ml Gd-DTPA makes the bolustracking technique to an ideal tool for the determination of the individual vessel c ourse, the haemodynamics and draining direction of an coronary anomaly with fistula.
