We evaluated the additional value of MR radiculography for increasing the sensitivity and specificity of MRI with regard to nerve root compression in patients with sciatica. The single slices of a heavily T2-weighted oblique coronal image set were reformatted with a maximum intensity projection protocol. This image resembles a classical contrast radiculogram and shows the intradural nerve root and its sleeve. In 43 patients studied with a standard MRI examination there was a need for further assessment of nerve root compression in 19 (44%). In 13 (68%) of these, MR radiculography made a definite verdict possible.
我们评估了磁共振神经根造影在提高坐骨神经痛患者磁共振成像（MRI）对神经根压迫诊断的敏感性和特异性方面的附加价值。使用最大强度投影协议对重度T2加权斜冠状位图像集的单一层面进行重新格式化。该图像类似于经典的造影神经根造影，显示硬膜内神经根及其鞘膜。在接受标准MRI检查的43例患者中，有19例（44%）需要进一步评估神经根压迫情况。其中13例（68%）通过磁共振神经根造影得出了明确的诊断结论。
