We report a case of a 50-year-old man with pseudocoarctation of the aorta that we examined with magnetic resonance imaging (MRI) and digital subtraction angiography (DSA). The MR images demonstrated the characteristic "kink" of the aorta and the absence of true coarctation. These appearances were confirmed by DSA, but we believe MRI to be the better method for examining the aorta because it is non-invasive and has the ability to display the mediastinal anatomy in the sagittal plane, in addition to the axial and coronal planes.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D001017	Aortic Coarctation	A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.

D013382	Subtraction Technique	Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. one without, radionuclide images using different radionuclides, radiograph vs. radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, coloring of vessels in angiograms).
