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

Study Status: Active, not recruiting
Recruit Status: Active, not recruiting
Study Type: Interventional

Official Title: US Elastography for Characterizing Focal Lesions in the Liver and Kidney

Brief Summary: 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.

Detailed Summary:

PRIMARY OBJECTIVES:

I. To determine the utility of ultrasound elastography in correlation with kidney or liver biopsy or magnetic resonance imaging (MRI) or computed tomography (CT) results.

OUTLINE:

Patients undergo ultrasound elastography.


Sponsor: Stanford University

Current Primary Outcome: 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).


Original Primary Outcome: Same as current

Current Secondary Outcome:
