The clinical value of magnetic resonance (MR) imaging was prospectively evaluated in 189 patients referred for examination of the brain or spine. Comparison of the attending physician's diagnosis, proposed treatment, and estimated prognosis before and after MR imaging indicated a substantial effect of the additional information provided by this study. A suspected diagnosis was refined or changed in 16% of all patients, and the physician's level of confidence in the diagnosis changed in over half of the cases in which the diagnosis was unchanged. In two-thirds of all cases the physician indicated that the treatment or estimated prognosis was altered.
对189名因脑部或脊柱检查而前来就诊的患者进行了磁共振成像（MR）临床价值的前瞻性评估。对比主治医生在磁共振成像前后的诊断、建议治疗方案和预估预后情况，结果显示该研究提供的额外信息产生了显著影响。在所有患者中，16%的疑似诊断得到了细化或改变，而在诊断未变的病例中，超过半数医生对诊断的信心程度发生了变化。在所有病例的三分之二当中，医生表示治疗方案或预估预后有所改变。
