Current and advanced structural and functional neuroimaging techniques are presented along with guidelines for utilization and principles of imaging diagnosis in fetal and neonatal central nervous system abnormalities. Pattern of injury, timing issues, and differential diagnosis are addressed with emphasis on neurovascular disease. Ultrasonography and computed tomography provide relatively rapid and important screening information regarding gross macrostructural abnormalities. However, current and advanced MRI techniques often provide more definitive macrostructural, microstructural, and functional imaging information.

Comparative StudySpinal cord stimulation prevents the effects of combined experimental ischemic and traumatic brain injury. An MR study.
Spinal cord stimulation (SCS) interferes with cerebral blood flow (CBF). In this paper we try to evaluate the possible preventing effect of SCS in an animal model of combined ischemic and traumatic injury. ⋯ MR examination was performed in all the animals at the end of the experiments. Compared to the control group none but one of the SCS showed lesional pattern far from the craniectomy suggesting a 'preventing' effect of SCS on the secondary damage associated with our model combined ischemic and traumatic brain injury.

Meta AnalysisReview of the use of somatosensory evoked potentials in the prediction of outcome after severe brain injury.
Review the predictive powers of somatosensory evoked potentials (SEPs) in severe brain injury. ⋯ SEPs are powerful predictors of outcome, particularly poor outcome, if patients with focal lesions, subdural effusions, and those who have had recent decompressive craniotomies are excluded.

Common causes to consultate a neuroradiologist in case of emergencies are trauma, brain infarction, or intracranial bleeding. Patients with brain infarction need a rapid assessment of the potentially nonnecrotic area within the ischaemic lesion. ⋯ With cranial computed tomography (CT) a thorough evaluation and staging of ischaemic stroke is possible with respect to thrombolysis. To detect irreversible damage of brain tissue, a combined perfusion-diffusion MRI should be performed.

To examine the utility of neuropsychological tests in assessing college athletes prior to and following a sports-related mild Traumatic Brain Injury (mTBI). ⋯ Neuropsychological tests are useful in the detection of cognitive impairment following mTBI. The test data appear to be more effective than subjective report of symptoms in differentiating between injured and noninjured athletes at 48 hours postinjury. Although significant individual variability existed, most injured athletes recovered within 1 week of injury. A battery of tests, rather than any single test, is necessary to capture the variability that exists among injured athletes.
