Comparative Study of Microvascular Flow and Viscoelasticity Imaging in Monitoring Renal Allograft Function

Listen to this summary

This study aimed to compare the effectiveness of microvascular flow imaging (MVFI) and ultrasound viscoelasticity imaging (UVI) in assessing the stability of renal allografts and their potential as noninvasive diagnostic tools for early dysfunction detection. The results indicated that MVFI, particularly the cortical color pixel percentage (cCPP), demonstrated superior diagnostic accuracy compared to UVI, with strong correlations to renal function metrics. The authors suggest that combining both imaging modalities could enhance monitoring and inform biopsy decisions in renal transplant recipients.
