Fig. 26

Coarctation of the aorta in the mid-thorax. This figure demonstrates the multiple ways a coarctation can be imaged by CMR. From left to right, there is 2D bright blood gadolinium enhanced imaging, a multiplanar reformat of a 3D dark blood sequence, a maximum intensity projection 3D image, inplane velocity mapping with color coding of the flow through the coarctation and a 3D volume rendered display. Note the collaterals on the maximum intensity projection and 3D volume rendered display. Color coding of the inplane velocity map is red cephalad and blue caudad
