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.

Condition or disease Intervention/treatment Phase
Adult Primary Liver Cancer Kidney Tumor Procedure: ultrasound elasticity imaging Not Applicable

Detailed Description:


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.


Patients undergo ultrasound elastography.

Arm Intervention/treatment
Experimental: Diagnostic (ultrasound elastography)
Patients undergo ultrasound elastography.
Procedure: ultrasound elasticity imaging
Undergo ultrasound elastography

Primary Outcome Measures :
  1. 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).
