The comparative adequacy was studied of the two main neuroradiological imaging methods, MR imaging and CT, through the analysis of 1500 MR examinations with a preliminary CT study. The comparison was made by giving a score to the diagnostic contribution of MR imaging, especially as far as changes in the therapeutical approach were concerned. The results varied according to the various pathologies, to the different anatomical regions explored, and to the site of the masses. The overall score was higher in the spine and the spinal cord than in brain pathology. In brain neoplastic pathology, eg, the diagnostic capabilities of CT and MR imaging were similar in most cases, especially in supratentorial locations, while MR imaging was clearly superior in the spinal cord district. In infratentorial location, the better anatomical details make MR imaging the method of choice. In conclusion, CT confirms its accuracy in the detection of brain pathology, while MR imaging proves more sensitive in white matter diseases, and in particular locations, e.g. the posterior fossa. In the spine and spinal cord districts, the very high average score mainly confirms MR capability to demonstrate spinal canal normal and pathological content. Moreover, the important role of MR imaging is stressed in pediatric pathology, together with CT primary role in emergency cases.
通过对1500例磁共振成像（MR成像）检查及初步CT检查的分析，对两种主要的神经放射成像方法，即MR成像和CT的相对充分性进行了研究。通过对MR成像的诊断贡献打分进行比较，尤其是就治疗方法的改变而言。结果因各种病理情况、所探索的不同解剖区域以及肿块的位置而异。脊柱和脊髓的总体得分高于脑部病变。例如，在脑部肿瘤性病变中，CT和MR成像的诊断能力在大多数情况下相似，尤其是在幕上部位，而MR成像在脊髓区域明显更具优势。在幕下部位，更好的解剖细节使MR成像成为首选方法。总之，CT在检测脑部病变方面证实了其准确性，而MR成像在白质疾病以及特定部位，如后颅窝，表现得更为敏感。在脊柱和脊髓区域，非常高的平均得分主要证实了MR成像显示椎管正常和病理内容的能力。此外，强调了MR成像在儿科病理中的重要作用，以及CT在急诊病例中的主要作用。
