Overview
Magnetic Resonance Imaging
- Acute stage (less than 7 days after onset): the hematoma typically appears isointense or slightly hypointense on T1-weighted images and markedly hypointense on T2-weighted images.
- Subacute stage (7 days to 7 weeks after onset): the hematoma appears hyperintense on T1- and T2-weighted images.
- Chronic stage (which typically begins 7 weeks after onset): a hypointense rim is present on T1- and T2-weighted images, which is attributed to hemosiderin deposition and the presence of a fibrous capsule.
