A prospective study was undertaken to compare the accuracy of surface coil magnetic resonance imaging (MRI) and computed tomography with myelography (CTM) in the determination of cervical radiculopathy with or without myelopathy. Twenty five patients underwent both imaging studies. The separately imaging diagnosis and the surgical findings were the basis of this study. The based-MRI and based-CTM predictions were not significant. MRI predicted two disc herniations that CTM did not predict. CTM predicted a combination of disk herniation and stenosis and one more lateral stenosis that MRI did not predict. Among the fourteen patients who underwent surgery, one underwent surgery only on based-MRI prediction, it was a disc herniation; one patient was operated on only on based-CTM prediction, it was a stenosis. In these operated patients, the predictive value of the both imaging modalities was not significant. In this report the diagnostic assessment of MRI and CTM was overall the same. The major advantages of MRI were its ability to display all the cervical spine, to study the disk pathology and to delineate a signal alteration within cord substance but the disadvantage was the difficulty to characterize the osteophytes made of cortical bone which did not give signal.
进行了一项前瞻性研究，以比较表面线圈磁共振成像（MRI）和脊髓造影计算机断层扫描（CTM）在确定有无脊髓病的颈椎神经根病方面的准确性。25例患者接受了这两种影像学检查。本研究以各自独立的影像学诊断和手术结果为基础。基于MRI和基于CTM的预测无显著差异。MRI预测了2例CTM未预测到的椎间盘突出。CTM预测了1例MRI未预测到的椎间盘突出合并狭窄以及1例额外的侧方狭窄。在接受手术的14例患者中，1例仅根据MRI预测进行了手术，为椎间盘突出；1例仅根据CTM预测进行了手术，为狭窄。在这些接受手术的患者中，两种影像学检查方法的预测价值均不显著。在本报告中，MRI和CTM的诊断评估总体相同。MRI的主要优点是能够显示整个颈椎，研究椎间盘病变，并描绘脊髓实质内的信号改变，但缺点是难以对由皮质骨构成且不产生信号的骨赘进行特征描述。
