[Proton spin tomography in the diagnosis of aortic isthmus stenosis in infancy].

We present the use of nuclear magnetic resonance imaging in the diagnostic work-up of coarctation in infancy. The diagnosis may be difficult with usual non-invasive methods, especially when shunts disguise the typical findings. Although magnetic resonance will certainly not be the method of choice in all cases, it should be seriously considered in infants when other non-invasive methods do not give a definite diagnosis.
