Overview
On MRI, rhabdomyosarcoma is characterized by low to intermediate intensity on T1, hyperintense on T2, and considerable contrast enhancement on T1 contrast.
MRI
On MRI, signal characteristics of rhabdomyosarcoma include:
- T1:
- Low to intermediate intensity, isointense to adjacent muscle.
- Areas of haemorrhage are common in alveolar and pleomorphic subtypes.
- T2:
- Hyperintense
- Prominent flow voids may be seen particularly in extremity lesions.
- T1 C+ (Gd):
- Shows considerable enhancement.
Embryonal rhabdomyosarcomas tend to be more homogenous, whereas alveolar and pleomorphic rhabdomyosarcomas frequently have areas of necrosis. The latter also has a predilection of ring-like enhancement
Cardiac MRI
Cardiac MRI can be used in rhabdomyosarcomas of the heart.

CMR may be used for clinical evaluation of cardiac masses, extracardiac structures, and involvement and characterization of masses in the differentiation of tumors from thrombi. |
