Fig. 5From: MRI evaluation prior to Transcatheter Aortic Valve Implantation (TAVI): When to acquire and how to interpretDiameters of sinuses of valsalva measured on MRI. 2-D SSFP of the aortic root in late diastolic phase is identified from the aortic root stack. Diameters are measured in mid-sinus above the aortic valve (a: noncoronary, b: left and c right). In the same patient corresponding CT images (d: noncoronary, e: left coronary and f: right coronary). Navigator-assisted 3-D SSFP or T2 black blood sequences can also be used for these measurementsBack to article page
