CHANGING OF MRI-SIGNAL PATTERNS OF THE FE MORAL-SHAFT IN PATIENTS AFTER RENAL-TRANSPLANTATION

In a prospective study 43 patients were reviewed 3 and 12 months after renal transplantation. The patients had MRI examinations and plain x- rays of the hips as well as punch biopsies of the iliac crest. In 9 pa tients diffuse, inhomogenous bilateral changings of the MRI-signal pat terns of the femoral diaphysis were seen. They were hypointense in the T1-weighted images and hyperintense in the STIR-images. All plain x-r ays were inconspicious. These changements of the femoral shaft were si gnificantly more frequent in patients with renal osteodystrophy of the histological type Delling IIa. We conclude that these changings of MR I-signals patterns might be connected with an osteoidosis.
