Hydronephrosis ARFI Study

May 29, 2015 updated by: Jonathan R. Dillman M.D., University of Michigan

Evaluation of Ultrasound Acoustic Radiation Force Impulse (ARFI)Shear Wave Velocity Imaging (SVI)in the Characterization of Pediatric Hydronephrosis

Pediatric upper urinary tract dilatation (hydronephrosis) is relatively common and may be either obstructive or nonobstructive. While the upper urinary tract is commonly evaluated by ultrasound, this imaging technique often fails to distinguish obstructed from nonobstructed systems. ARFI SVI is a new ultrasound technology that can be used to determine stiffness by measuring a tissue's shear wave velocity, may show alterations in parenchymal shear wave velocity in kidneys that show obstruction on DRS (Diuretic renal scintigraphy)which serves as the reference standard.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ARFI-SVI Ultrasound
Ultrasound scan using acoustic radiation force impulse-shear wave velocity imaging in the characterization of pediatric hydronephrosis. This is a non-invasive scan that uses sound waves to create the images.
Procedure: AFRI-SVI Ultrasound
This research scan uses acoustic radiation force impulse (ARFI) shear wave velocity imaging (SVI)a new ultrasound technology in which unique sound waves create the images/pictures of the kidney beng examined/scanned. This ultrasound scan will take approximately 10 minutes to complete.
