Abstract:
Objective To examine aortic dissection by using T1W/TFE sequence and to observe the imaging characteristics of aortic dissection in T1W/TFE sequence. Methods Twenty patients confirmed as aortic dissection by CT and ultrasound received MRI scanning of T1W/TFE sequence on inclined sagittal and SE sequence on transaxial at Philips Gyroscan 1.5 MR imager. The signal changes of aortic dissection in T1W/TFE sequence were observed. Results In T1W/TFE sequence, we observed not only an intimal flap, a double lumen and range of aortic dissection, but also the site of intimal tear and thrombus in the false lumen. Conclusion By using T1W/TFE sequence we obtained the high quality image of aortic dissection and high contrast of imaging. Combined with SE sequence , T1W/TFE sequence can provide reliable information for analyzing and curing aortic dissection in clinic.
