Overview
On MRI, necrotizing fasciitis is characterized by features such as loss of muscle texture and high signal intensity compatible with intramuscular hemorrhage in T1 weighted image. On T2-weighted images, subcutaneous and intramuscular edema in a reticulated pattern and subfascial and interfascial crescentic fluid collection are seen.
MRI
On MRI, necrotizing fasciitis is characterized by the following features:[1][2][3]
- T1- weighted image:
- Loss of muscle texture and may show high signal intensity compatible with intramuscular hemorrhage
- T2- weighted image:
- Subcutaneous and intramuscular edema in a reticulated pattern
- Subfascial and interfascial crescentic fluid collection
