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

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.

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.

Inclusion Criteria:

• There are no restrictions on life expectancy
• Eastern Cooperative Oncology Group (ECOG) or Karnofsky performance status will not be employed
• Patients of any ethnic background
• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

• Patients should not be taking other investigational agents
• No requirements due to co-morbid disease or intercurrent illness, as needed
• No restrictions on allergic reactions as no imaging agent will be used
• Concomitant medications for treatment of the target lesion
• Pregnant or nursing patients will be excluded from the study
