Overview
MRI is preferred over CT, especially for truncal and extremity desmoid tumors. On MRI, desmoid tumor has variable characteristics depending on their cellularity and fibrous content with loss of signal following fat saturation. They appear isointense/hypointense on T1 and hyperintense on T2.
MRI
- MRI is required in order to:
- Define the relationship of the tumor to adjacent structures
- Assess resectability
- Find out the need for treatment
- Monitor recurrence after surgery
- MRI is preferred over CT, especially for truncal and extremity tumors
- MRI characteristics of desmoid tumors are variable depending on their cellularity and fibrous content:[1][2][3][4]
