One advantage of MRA chest is that it can be combined with MRI heart function and morphology to quantify the degree of collaterals around the coarctation, more accurately estimate pressure gradients across the coarctation, and assess associated cardiac and conotruncal abnormalities [81,82]. MRI Heart Function and Morphology MRI heart function and morphology can quantify the degree of collaterals around the coarctation. It can also be easily combined with an MRA chest to provide more comprehensive evaluation in patients with aortic coractation and associated cardiac and conotruncal abnormalities [75]. Congenital or Acquired Heart Disease MRI Heart Function with Stress There is no relevant literature to support the additional use of MRI heart function with stress in the evaluation of suspected aortic coarctation. MRA Neck There is no relevant literature to support the use of MRA neck in the evaluation of suspected aortic coarctation. Radiography Chest Radiography chest has limited clinical utility in diagnosis. Conventional signs on the chest radiograph may be subtle and not always easy to appreciate but may provide clues about the presence of an aortic coarctation. SPECT or SPECT/CT MPI Rest and Stress There is no relevant literature to support the use of SPECT or SPECT/CT MPI rest and stress in the evaluation of suspected aortic coarctation. FDG-PET/CT Heart There is no relevant literature to support the use of FDG-PET/CT heart in the evaluation of suspected aortic coarctation. US Echocardiography Transesophageal TEE is used for intraoperative imaging when other cardiac abnormalities are present in conjunction with CoA. The role of TEE for Doppler examination is limited because the ultrasound beam is almost perpendicular to the line of blood flow, leading to inaccuracies in velocity estimation.
