[Value of magnetic resonance imaging in the follow-up of children operated for portal hypertension].
The authors report their experience concerning nuclear magnetic resonance imaging (NMR) in 7 children. They emphasize its importance in the post-operative study of portal hypertension. All those children got surgically created porto-systemic shunts. NMR imaging is easy, safe and trustable. It is able to visualise the shunt itself and to demonstrate the patency of this shunt. So, it is interesting when the usual controls have failed, particularly abdominal ultrasonography.
