A Study of Renal Microvessel Imaging for Chronic Kidney Disease
September 11, 2023 updated by: Shigao Chen, Mayo Clinic
Renal Microvessel Imaging for Characterization of Chronic Kidney Disease
The purpose of this research is to study the efficacy of ultrasound microvessel imaging for evaluation of Chronic Kidney Disease.
Definity is an ultrasound contrast agent currently approved by the FDA for use on the heart, liver, and urinary tract.
This study will look at its effectiveness on the kidney.

Intervention / Treatment |
---|---|
Experimental: Chronic Kidney Disease Group
Subjects with Chronic Kidney Disease (CKD) with clinically indicated renal biopsy will have microvessel images obtained by Super-Resolution Ultrasound Imaging (SRUI) using Definity ultrasound contrast agent.
|
Imaging technology for microvessel imaging.
This technology localizes and tracks individual microbubbles (FDA approved ultrasound contrast agents) to map microvessel morphology and flow speed at a spatial resolution about 10 times higher than conventional ultrasound imaging.
Other Names:
Ultrasound contrast agent administered intravenously
