OBJECTIVE
To evaluate the stage of maturation and the metabolism of neurogenic heterotopic ossification by using SPECT/CT.
METHODS
A total of 12 medical records of patients with spinal cord injury, all of them classified according to the ASIA protocol (disability scale from the American Spinal Injury Association) in complete lesion (A) and partial lesions (B, C and D) and registered at the Laboratory of Biomechanics and Rehabilitation of the Locomotor System, were submitted to SPECT/CT evaluation.
RESULTS
Sixteen hips with heterotopic ossification observed in X-ray were studied and only two (12.5%) had high osteoblastic activity. Five hips showed medium activity, three (18.75%) low activity and six (37.5%) did not present any activity detected by SPECT/CT.
CONCLUSION
SPECT/CT helps to determinate which patients have a greater risk of relapse after surgical resection, proving to be a useful imaging study in preoperative evaluation that can be used to determinate the postoperative prognosis of these patients. Level of Evidence III, Investigating a Diagnostic Test.
目的
利用单光子发射计算机断层扫描/计算机断层扫描（SPECT/CT）评估神经源性异位骨化的成熟阶段和代谢情况。
方法
共有12例脊髓损伤患者的病历资料，所有患者均根据美国脊髓损伤协会（ASIA）协议（美国脊髓损伤协会残疾量表）分为完全损伤（A）和部分损伤（B、C和D），并在运动系统生物力学与康复实验室进行登记，接受SPECT/CT评估。
结果
对X线检查发现有异位骨化的16个髋关节进行了研究，只有2个（12.5%）具有高成骨活性。5个髋关节显示中等活性，3个（18.75%）显示低活性，6个（37.5%）未检测到SPECT/CT显示的任何活性。
结论
SPECT/CT有助于确定哪些患者在手术切除后复发风险更高，在术前评估中被证明是一项有用的影像学检查，可用于确定这些患者的术后预后。证据级别III，诊断试验研究。
