Head Trauma - MR diffusion
Search Pattern Assist ?Exam
Purpose
2. Identify areas of infarction (DWI & ADC diffusion positive) related to arterial vascular injury or vasospasm; these will undergo encephalomalacia
Findings
MR diffusion (DWI & ADC maps)
There is evidence of positive MR-diffusion but negative ADC (edema shine-through effect) associated with intraaxial parenchymal injury not evident on CT or other MR sequences. [Yes/No]
There is evidence of positive MR-diffusion and ADC (actual positive restriction) in areas of post traumatic or hypoxic cytogenic edema or intercurrent arterial occlusion. [Yes/No]
The distribution of the positive sites on the DWI are consistent with a single trauma vector versus vectors of different directions (shaking) in NAI patients. [Yes/No]
There is positive diffusion and positive ADC associated with intraaxial parenchymal injury and local ischemic effects not evident on CT or other MR sequences. This is especially evident in infants (< 1 year old) with NAI. [Yes/No]
Other
There is evidence of concurrent abnormalities not likely related to recent brain injury. [Yes/No]
