The Clinical Efficacy of Magnetic Resonance Imaging in Neuroimaging Ann Int Med 120:856-871, 872-8751994., Kent,D.L.,et al, 1994 See this aricle in Pubmed Article Abstract For most abnormalities,the sensitivity of MRI is equal or better than competing technologies.Magnetic resonance imaging shows greater contrast and detail than computed tomography(CT)but also shows more clinically silent abnormalities or incidental findings.A few studies found a modest impact on therapeutic choices but no impact on quality of life or disability.Costs for MRI are high.Computed tomography is sufficient for initial diagnosis of most mass lesions or intracranial hemorrhages requiring immediate intervention.Magnetic resonance imaging is more accurate in the temporal lobes,posterior fossa,brainstem,and spinal cord. For lumbar radiculopathy,MRI and plain spinal CT are as accurate as postmyelographic CT and are less invasive.The role of magnetic resonance angiography for carotid artery disease is being studied.Although suggestions for appropriate use can be made,the supporting evidence in published studies is weak.Firm guidelines for appropriate use of MRI should be based on further clinical research using more rigorous methods.
