Traumatic brain injury often results in brain lesions which are subtle. Current conventional MRI techniques (GRE and SWI) are field strength and echo time dependent, causing lesions to possible be missed. QSM methods can overcome this, but with many artifacts and missed lesions due to masking artifacts. TFI QSM can overcome this issue, as we demonstrate in this study of TBI patients.
