55 patients were examined by magnetic resonance imaging after lumbar disk operation. The results indicate that with Gd-DTPA there is a significantly increased signal intensity along the surgical approach directly after surgery and during the early postoperative period. Whereas herniated or sequestered disk did not enhance with Gd-DTPA, in epidural fibrosis - regardless of the age of the scarification - diagnostic enhancement was obvious. In 82 percent nerve roots engulfed by scar tissue were differentiated after Gd-DTPA; even enlarged nerve roots and changes of arachnoiditis could be differentiated from each other.
55例患者在腰椎间盘手术后接受了磁共振成像检查。结果表明，使用钆喷酸葡胺（Gd-DTPA）时，术后即刻及术后早期沿手术入路的信号强度显著增加。而突出或游离的椎间盘在使用Gd-DTPA时无强化，在硬膜外纤维化中——无论瘢痕形成的时间长短——诊断性强化均很明显。在使用Gd-DTPA后，82%被瘢痕组织包绕的神经根可被区分出来；甚至扩大的神经根和蛛网膜炎的改变也能相互区分。
