Clinical 4D flow MRI assessment in aortopathy-what the clinician needs to know.

ABSTRACT: Interval cross-sectional imaging plays an important role in aortopathy surveillance. Often, cardiac magnetic resonance imaging (MRI) is used over computed tomography (CT) due to the lack of radiation in repeated surveillance and the option of additional hemodynamic assessment. Primarily, assessment includes the orthogonal measurement of aortic dimensions in a three-dimensional (3D) structure. Lately, four-dimensional (4D) flow MRI is becoming more widespread as it can be acquired within 1-5 minutes using advanced techniques. In addition to standard flow quantification, 4D flow MRI offers advanced hemodynamic quantification. This review discusses important advanced imaging biomarkers, including helical flow pattern, wall shear stress (WSS), flow displacement and systolic flow reversal ratio
