An observational study was undertaken to obtain measures of the impact of magnetic resonance imaging (MRI) on diagnosis, patient management and patient outcome. A minimum data set at the time of examination was used for 1119 consecutive patients referred by specialists for MRI of the brain or spine. Three month follow up of 707 brain examinations and 235 spinal examinations was undertaken using a questionnaire on diagnosis and patient management. Magnetic resonance imaging made a dominant contribution to final diagnoses of neoplasia and vascular disorders, but was less significant for white matter disease. In a high proportion of cases other types of examination also influenced the final diagnosis. Magnetic resonance imaging affected patient management in a high proportion of spinal examinations and in cases of cerebral neoplasm, with lesser contributions to cases of cerebrovascular disorder and white matter disease. While MRI was considered superior to other imaging methods, which it could often replace, in practice it will form only one input to the diagnostic decision.
开展了一项观察性研究，以获取磁共振成像（MRI）对诊断、患者管理及患者预后影响的相关指标。对由专科医生转诊来进行脑部或脊柱MRI检查的1119例连续患者，在检查时采用了一个最小数据集。通过一份关于诊断和患者管理的问卷，对707例脑部检查和235例脊柱检查进行了为期三个月的随访。磁共振成像对肿瘤形成和血管疾病的最终诊断起主要作用，但对白质疾病的诊断意义较小。在很大比例的病例中，其他类型的检查也影响了最终诊断。磁共振成像在很大比例的脊柱检查及脑肿瘤病例中影响了患者管理，而对脑血管疾病和白质疾病病例的影响较小。虽然MRI被认为优于其他成像方法，且常常可以替代它们，但在实际中它只是诊断决策的一个输入因素。
