Correlation of MR markers with interstitial fibrosis / tubular atrophy lesions on biopsy
Achtergrond van het onderzoek
The aim of the study is to detect (focal) interstitial fibrosis or rubular atrophy lesions in kidney allografts using MRI. Three groups of subjects are included: subjects >3 months after transplantation with stable graft function who preferably do have a routine kidney biopsy; subjects >6 months after transplantation suspect for chronic allograft dysfunction with an indication biopsy; healthy volunteers without kidney disease as comparison. All participants get a one-hour MRI scan to measure several functional parameters of kidney function. Correlations with biopsy and differences between groups will be investigated.
Doel van het onderzoek
To investigate whether it is possible to indicate (focal) interstitial fibrosis / tubular atrophy lesions in kidney allografts with MRI and compare these findings to the extent of interstitial fibrosis / tubular atrophy in the kidney biopsy that will be taken according to current clinical practice.

• Patients are 18 year or older.
• Kidney biopsy is performed according to the existing guidelines for clinical practice just prior to or shortly after the MRI-scan has been performed
• Time between NTx and inclusion must be at least 3 months for patients with well functioning transplants and 6 months for patients with suspected chronic allograft dysfunction
Also healthy volunteers are included as comparison.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
