Abstract
|
|
|
In the last decade Computed Tomography (CT) has played a critical role in the diagnostic evaluation of the patients with focal brain injury.
But it is apparent from pathologic studies that CT underestimates the severity of the many forms of cerebral injury such as primary brain stem injury, non-hemorrhagic cortical contusion and diffuse axonal injury (DAI).
Magnetic Resonance Imaging (MRI), however, has been shown to be highly sensitive in detecting diffuse brain injury (DBI). Among the consecutive 13 cases of DBI patients in this series for 10 months, twelve patients were verified as MR evidence of
injury
in prospective studies. The anatomical distribution of the injuries were 11 cases of corpus callosal lesion, 6 cases of lobar white matter lesion, 1 case of primary brain stem lesion. The sensitivities of MR imaging in detecting the primary
lesion
were
76.9% (10/13) in TlWI and 92.3% (12/13) in T2WI.
In DBI, patients with callosal injuries had higher incidence (8/12) than lobar white matter and primary brain stem lesion, the corpus callosal atrophy by midsaggital MR imaging and behavioral seguellae in survivors of severe head implicate the
corpus
callosal injury and degeneration.
More accurate detection and delineation of traumatic lesions with MR should permit more accurate prediction of neurologic and cognitive recovery and assist in optimizing form of treatment.
