Overview
MRI may be helpful in the diagnosis of Wilms' tumor.
MRI
- Abdominal MRI may be helpful in the diagnosis of wilms tumor.
- One of the most important role of MRI in wilms tumor is to determine if tumor invaded inferior vena cava or not.
- The findings of MRI are:
- Low signal intensity on T1-weighted images.
- high signal intensity on T2-weighted images.
Abdominal magnetic resonance imaging (MRI) is reportedly the most sensitive imaging modality for determination of caval patency and may be important in determining whether the inferior vena cava is directly invaded by the tumor. Wilms tumor demonstrates low signal intensity on T1-weighted images and high signal intensity on T2-weighted images.
MRI is probably the most accurate modality in assessing for IVC involvement . These tumours appear heterogeneous on all sequences and frequently contain blood products, but typically are:[1]
- T1: hypointense
- T1 C+ (Gd): heterogeneous enhancement
- T2: hyperintense
