Clinical PC VIPR Implementation for Abdominal Hemodynamics Assessment in Patients with Renal Cell Carcinoma Tumor Thrombus

Motivation: 4D flow MRI provides volumetric time-resolved blood flow measurements in short scan times. Nevertheless, 4D Flow MRI techniques have not been clinically applied to abdominal neoplasms invading into the vasculature, altering blood flow and posing unique surgical problems. Goal(s): Describe the clinical implementation of 4D Flow MRI for treatment planning of RCC patients with venous tumor thrombus undergoing nephrectomy and thrombectomy. Approach: Our institution has established a 4D flow MRI workflow for blood flow assessment based on multidisciplinary collaboration and several other factors. Results: Clinical 4D flow for treatment planning of RCC patients has been successfully implemented at our institution. Impact: 4D flow MRI allows for comprehensive non-invasive assessment of the abdominal circulation in the clinical setting. The methodology presented here has provided unvaluable input to the care team of patients with complicated cases of advanced RCC during treatment planning.
