[Duplex sonography and magnetic resonance tomography in the clarification of nephrologic complications following kidney transplantation].
A prospective study compared duplex sonography and magnetic resonance imaging in evaluating renal transplants. One hundred and two duplex sonographic and 24 MR examinations were performed and correlated with clinical course or biopsy. All normal renal allografts, 6 transplants with acute tubular necrosis and 2 cases of cyclosporin toxicity had normal Doppler waveforms, whereas 9 renal transplants with evidence of interstitial rejection by biopsy showed an obliteration or reversal of diastolic flow. MR imaging was less specific in identifying allograft rejection. There were false positive results in normal renal transplants, allografts with acute tubular necrosis and after rejection therapy. With regard to cost, accessibility and specificity, duplex sonography is the method of choice for the evaluation of renal allografts.
