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-treatment cross sectional imaging.
II. To assess the potential added value of using multi-modality volumetric CEUS for detecting RCC recurrence post ablation.
III. To explore the use of quantitative imaging parameters extracted from 2D/3D CEUS datasets to determine if this improves the overall performance of CEUS.
EXPLORATORY OBJECTIVE:
I. An advanced Doppler technique designed for detection of slower flow will also be investigated as a non-contrast based approach for detecting recurrent disease.
OUTLINE:
Patients receive Lumason intravenously (IV) and undergo CEUS imaging with MRI/CT on study. Patients' electronic medical record is reviewed every 6 months throughout study.
