Magnetic resonance (MR) evaluation was performed on patients with titanium spine implants. The objective was to determine the value of conventional MR for evaluating the postoperative spine with titanium implants. The value of MR imaging for evaluation of the postoperative spine without metal implants is well known. The results of MR evaluation of the titanium instrumented spine have not been explored. Thirty patients with titanium spine implants underwent MR evaluation. Indications included pain, neurologic deficit, decompression evaluation, and infection. The titanium implants caused only local MR signal void and did not interfere with the imaging of the adjacent soft tissues. This provided significant information and helped determine whether further surgical intervention was required. There is significant value of MR evaluation of the post-operative spine without compromise from titanium implants.
对患有钛制脊柱植入物的患者进行了磁共振（MR）评估。目的是确定传统MR在评估钛植入物术后脊柱方面的价值。MR成像在评估无金属植入物的术后脊柱方面的价值是众所周知的。钛制器械脊柱的MR评估结果尚未得到探讨。30例患有钛制脊柱植入物的患者接受了MR评估。适应症包括疼痛、神经功能缺损、减压评估和感染。钛植入物仅导致局部MR信号缺失，并未干扰相邻软组织的成像。这提供了重要信息，并有助于确定是否需要进一步的手术干预。对术后脊柱进行MR评估具有重要价值，不受钛植入物的影响。
