Overview
On MRI, chondrosarcoma is characterized by low to intermediate signal on T1, very high intensity in calcified portions on T2, and moderate to intense contrast enhancement on T1 contrast.
MRI
MRI findings of chondrosarcoma include:[1][2][3][4]
- T1 image:
- Low to intermediate signal.
- Iso- to slightly hyperintense signal of muscle.
- T2 image:
- Very high intensity in non-mineralised or calcified portions.
- T1 C+ (Gd) image:
- Most demonstrate heterogeneous moderate to intense contrast enhancement.
- Enhancement can be septal and peripheral rim-like corresponding to fibrovascular septation between lobules of hyaline cartilage.
