We studied the utility of fluid-attenuated inversion-recovery (FLAIR) MRI in the investigation of head injury. We examined 56 patients with head injuries with T2-weighted spin-echo (SE) and FLAIR sequences. In all cases, the sensitivity of FLAIR images to equal or superior to that of conven...

These methods are briefly introduced in the context of studies in head injury and example data are presented in a case study of mild head injury. These techniques revealed damage to the brain tissue extending well beyond the areas of focal lesion seen by conventional MRI.Blamire A....

Head and neck (Fig. 1). MRI can be used to detect brain tumors, traumatic brain injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, and the causes of headache. Figure 1. MRI of the brain.Arteries and veins (Fig. 2). MRA can detect aneurysms, blockages of ...
It is used to observe brain structures and to determine which parts of the brain are handling critical functions. Functional MRI may also be used to evaluate damage from a head injury or Alzheimer's disease. fMRI has been especially useful in neuroscience — "It has really revolutionized how ...
