This phase II trial studies how well contrast-enhanced ultrasound (CEUS) works for diagnosing patients with renal cell cancer (RCC) that has come back (recurrent) after an ablation. Diagnostic imaging, such as CEUS, may help find and monitor long term renal cell cancer recurrence following cryo or microwave ablation.
PRIMARY OBJECTIVE: I. To characterize and compare the sensitivity, specificity, positive and negative predictive value, and inter-reader agreement of 2D contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CT)/magnetic resonance imaging (MRI) for detecting recurrent or residual renal cell carcinoma (RCC) following ablation, using a combination of standard of care imaging follow-up and tissue pathology as a reference standard. SECONDARY OBJECTIVES: I. To evaluate the potential improvement to the qualitative assessments of 2D CEUS when fused with the patient's pre-tr…
Inclusion Criteria: * Previously received cryotherapy or microwave therapy of RCC * Has available contrast enhanced (CE)-MRI or CE-CT imaging prior to ablative therapy * Have previously had or are scheduled to have a contrast-enhanced MRI/CT for the monitoring of RCC recurrence within 4 weeks of the CEUS study * Be at least 18 years of age * Be medically stable * If a female of child-bearing age, must have a negative pregnancy test * Have signed Informed Consent to participate in the study Exclusion Criteria: * Patients who are medically unstable, patients who are seriously or terminally il…
