Kernspintomographie des thorakalen Aortenaneurysmas

The results of magnetic resonance imaging in 16 patients with non-dissecting aneurysm of the thoracic aorta are presented. Scans with ECG-gated spin-echo sequences in transversal, coronal, and left anterior oblique views demonstrated the size and extent of the aneurysms. Measurements of the maximum aneurysmal diameter differed by less than 5 mm from measurements obtained with computed tomography. In 6 of 7 patients with presence of wall adherent intraluminal signal, phase images were able to differentiate accurately between mural thrombus and slow blood flow.
