Conclusion

Our data suggest that the three sequences have high levels of inter-operator concordance showing the feasibility of an unenhanced MRA technique for the evaluation of the thoracic aorta in patients who have a contraindication to a CE – MRA study. If diameter measurement is the main clinical concern, 2D-SSPP is a good choice good; on the other hand, between CE-MRA sequences, 4DTR-MRA is more advisable than 3DCE-RMA because need less quantity of contrast medium.
