A NOVEL METHOD OF SONOGRAPHIC TISSUE PERFUSION MEASUREMENT IN RENAL TRANSPLANTS

Problemstellung: Renal transplants' normal function depends on sufficient parenchymal perfusion. Chronic function loss may be a consequence of transplant vasculopathy – the loss of small parenchymal vessels. Today transplant biopsy is used to diagnose such vascular changes. A non-invasive procedure is wanted to detect and follow up parenchymal vascular changes in renal transplants. We present the novel PixelFlux technique of dynamic (heart action averaged), automatic (software based), quantitative Doppler sonographic tissue perfusion measurement to monitor parenchymal vascular state. Methoden: We investigated re…
