Abstract

PURPOSE: To evaluate and compare findings for thoracic aortic disease withthree black-blood magnetic resonance (MR) pulse sequences: half-fourier rapid acquisition with relaxation enhancement (RARE), with and without electrocardiographic (ECC) triggering, and ECC-triggered turbo spin echo (SE). MATERIALS AND METHODS: Axial black-blood MR images of the chest acquired at 1.5 T with a phased-array coil were obtained in 38 consecutive patients referred for evaluation of thoracic aortic disease. EGG-triggered and nontriggered half-fourier RARE images were compared with T1-weighted ECC-triggered turbo SE images. Two readers independently scored images for each of the following parameters: ghosting artifacts; clarity of the mediastinum, cardiac chambers, and aortic wall; conspicuity of abnormality; intraluminal signal void uniformity; and overall image quality. RESULTS: Both half-fourier RARE sequences outperformed the turbo SE sequence for all measured parameters. Scores for the EGG-triggered half-fourier RARE sequence were significantly (P <.05) higher than those for the nontriggered version for clarity of the mediastinum and aortic wall, conspicuity ofany abnormality other than aortic dissection, and overall image quality. Mean acquisition times for the EGG-triggered (48 seconds) and nontriggered (30 seconds) sequences were significantly shorter than that for the turbo SEsequence (2 minutes 20 seconds). CONCLUSION: Rapid black-blood half-fourier RARE sequences, with or withoutECC triggering, can replace ECC-triggered turbo SE sequences for evaluation of thoracic aortic disease.
