Abstract
The magnetic resonance phase-contrast technique for the measurement of flow velocity
and volume in true and false lumens was studied in six patients with chronic dissecting
aneurysms. Phase-contrast images were obtained at a level perpendicular to the dissecting
aneurysms of the descending aorta. As the maximum diameter of aneurysms increased,
the ratio of the cross-sectional area of the false to the true lumen increased and
the peak average velocity in the true lumen during systole was decreased. This technique
proved invaluable for determining prognosis and operability for this condition.
