4D flow CMR velocity maximal intensity projection (MIP) (A) and time-resolved CMRA (TR-CMRA) MIP in a patient with type B aortic dissection. While TR-CMRA demonstrates dynamic filling of the proximal false lumen (FL), 4D flow exhibits a prominent entry tear jet impinging on the wall of the distal arch (white arrow). At least one smaller hemodynamically active fenestration is also seen more distal to the primary entry tear (arrowhead). TL: true lumen. Figure courtesy of Bradley D.
