Overview
an MRI may be used to diagnose and for follow-up of renal cell carcinoma.
MRI
Renal MRI may be helpful in the diagnosis of renal cell carcinoma. Due to the use of IV gadolinium in MRI, the risk of nephrogenic systemic fibrosis (NSF) must always be considered.[1] It is a rare condition and often has cutaneous manifestations, but may affect any organ. Risk factors for development of NSF include:
- High dose of gadolinium-based contrast
- Acute and chronic renal failure
- Vascular injury
| Patient Profile | Use of MRI | Evidence Strength |
| Low Risk Patient (pT1, N0, Nx) | Baseline abdominal MRI (or CT) for nephron sparing surgery and CT (or US or MRI) for radical nephrectomy within 3-12 months following renal surgery Additional MRI (or US or CT) may be performed in patients following radical nephrectomy if initial post-op baseline image is negative |
Expert opinion C |
| Moderate to High Risk Patients (pT2-4N0 Nx or any stage N+) | Baseline chest and abdominal MRI (or CT) within 3-6 months following surgery with continued imaging (US, CXR, CT, or MRI) every 6 months for at least 3 years and annually thereafter to 5 years. Site specific imaging is warranted by clinical symptoms suggestive of recurrence or metastatic spread. Imaging (US, CXR, CT, or MRI) beyond 5 years may be performed at the discretion of the clinician | C |
| Active surveillance | Cross-sectional abdominal scanning (CT or MRI) within 6 months of active surveillance initiation to establish a growth rate. Further imaging is recommended at least annually thereafter | C |
| Ablation | Patients undergo cross-sectional CT or MRI with and without IV contrast unless contraindicated at 3 and 6 months following ablative therapy to assess treatment success. Annual abdominal CT or MRI should follow for 5 years. Individual MRI (or CT) beyond 5 years is based on individual patient risk factors | C |
