Ultrasound Elastography in Diagnosing Patients With Kidney or Liver Solid Focal Lesions

June 6, 2017 updated by: Juergen Willmann, Stanford University

US Elastography for Characterizing Focal Lesions in the Liver and Kidney

This clinical trial studies ultrasound elastography in diagnosing patients with kidney or liver solid focal lesions. New diagnostic procedures, such as ultrasound elastography, may be a less invasive way to check for kidney or liver solid focal lesions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Strain ratio for all lesions measured by comparing the lesion to the adjacent normal tissue
Time Frame: Up to 36 months
Suspicious liver and kidney lesions will be analyzed separately on a per-lesion basis. Within each population, the strain ratio of cases and controls will be compared using the Wilcoxon rank sum test, and the analysis will be illustrated using the non-parametric receiver operating characteristic (ROC).
Up to 36 months
