IRB 14-009240, Does CEUS Positively Influence Selection of Biopsy Sites When Evaluating Transplant Kidneys?

• Status: Completed
• Trial end date: 2019-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a pilot study to investigate whether contrast-enhanced ultrasound (CEUS) may help evaluate segmental differences in renal perfusion better than Doppler Ultrasound and thus help direct the biopsy to the most abnormal part of the renal cortex. This should maximize detection and increase the odds of demonstrating the true grade/severity of the histopathological abnormality.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Mayo Clinic

Criteria

Inclusion

Exclusion:

• Pregnant women or women who are nursing an infant are not able to participate in this study
