Summary
Magnetic resonance imaging (MRI) with or without contrast is the study of choice when cerebellar, brainstem, or internal auditory meatus pathology is suspected. Similarly, the yield of computed tomography (CT) brain scans is minimal in patients with syncope or near syncope. Suspected spinal cord compression is best defined by MRI. Traumatic or atraumatic myelopathy should be investigated with emergent MRI. In case of nontraumatic myelopathy, the entire spine must be evaluated by MRI. Ready access to CT and its accurate interpretation is essential in evaluating the patient presenting with a new ischemic neurological deficit. Epidural hematomas are often associated with skull fractures, which should be evaluated with CT bone settings and the plain radiography. Most of epidural hematomas result from laceration of the meningeal arteries and/or dural venous sinuses. MRI is particularly sensitive in demonstrating subacute subdural hematomas because of its inherent soft tissue contrast characteristics and its multiplanar capability.
