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

• T1:

• Low to intermediate signal.
• Iso- to slightly hyper intense cf. muscle.

• T2: very high intensity in nonmineralised/calcified portions.
• T1 C+ (Gd):

• 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.
