Sequence | Imaging plane | Indication |
---|---|---|
Standard imaging | ||
Cine bSSFP | Parallel to the LVOT in orthogonal planes, short axis of the aortic root, Short-axis of the largest diameter of the ascending aorta, sagittal oblique in long axis of the aortic arch (“candy cane”) | Aortic valve morphology, measurement of aortic root and ascending aorta, and assessment of aortic arch anatomy |
Contrast-enhanced magnetic resonance angiography | 3D volume, extend field of view superiorly to angle of the jaw | Extracardiac vascular anatomy for aneurysm formation and vertebral tortuosity |
3D bSSFP, GRE or mDIXON FSE respiratory navigator-gated and ECG-triggered whole heart sequencea | 3D volume | Extracardiac vascular assessment for aneurysm formation, measurement of aortic root |
Phase contrast flow | Ascending aorta Descending aorta | Flow velocity and pattern |
Additional case-specific or comprehensive imaging | ||
Cine bSSFP | Ventricular short-axis or axial (transverse) stack | LV volumes, mass, and EF RV volumes, mass, and EF |
Cine bSSFP | Extend field of view to include head, neck, abdomen, and pelvis | Loeys-Dietz syndrome |
Proton-density-weighted FSE black blood imaging | Sagittal oblique in long axis of the aortic arch (“candy cane”) | Vascular anatomy |
Cine bSSFP | Short and long axis of the region of interest | Concern for dissection or interarterial thrombus |
