MRI: The degree of brain swelling and edema are better seen on MRI than on CT scan. As dar as prognostic indicators, it is more of a wait and see situation to determine how much function will return.
Dr. Charles Whiting

Soft Tissue Injury: MRI is much better at seeing soft tissue while CT is very good at seeing bones and hard tissues. Since the brain is very soft tissue, an MRI can visualize an injury much earlier than CT. Seeing the extent of the injury by MRI would allow a doctor to estimate a prognosis in the case of a near-drowning. Best wishes!

I agree with Dr. Whiting: MRI has significant prognostic value over CT in a child with near drowning. Here is a recently published paper: http://www.scielo.br/pdf/anp/v67n1/a14v67n1

MRI more accurate: Neuroimaging techniques can add valuable information (MRI) shows characteristic patterns depending on severity of the injury and also timing of imaging. Degree of edema and brain swelling is better seen by MRI than by computer tomography, therefore CT scans are not widely used for early outcome prediction.
