The aim of the study was to evaluate the commercially available orthopedic metal artifact reduction (OMAR) technique in postoperative three-dimensional computed tomography (3DCT) reconstruction studies after spinal instrumentation and to investigate its clinical application.
One hundred and twenty (120) patients with spinal metallic implants were included in the study. All had 3DCT reconstruction examinations using the OMAR software after obtaining the informed consents and approval of the Institution Ethical Committee. The degree of the artifacts, the related muscular density, the clearness of intermuscular fat planes, and definition of the adjacent vertebrae were qualitatively evaluated. The diagnostic satisfaction and quality of the 3D reconstruction images were thoroughly assessed.
The majority (96.7%) of 3DCT reconstruction images performed were considered satisfactory to excellent for diagnosis. Only 3.3% of the reconstructed images had rendered unacceptable diagnostic quality.
OMAR can effectively reduce metallic artifacts in patients with spinal instrumentation with highly diagnostic 3DCT reconstruction images.
本研究的目的是评估在脊柱内固定术后三维计算机断层扫描(3DCT)重建研究中商用的骨科金属伪影减少(OMAR)技术,并研究其临床应用。
本研究纳入了120例有脊柱金属植入物的患者。所有患者在获得机构伦理委员会的知情同意和批准后,使用OMAR软件进行了3DCT重建检查。对伪影程度、相关肌肉密度、肌间脂肪平面清晰度以及相邻椎体的清晰度进行了定性评估。对3D重建图像的诊断满意度和质量进行了全面评估。
大多数(96.7%)的3DCT重建图像被认为诊断满意度为满意至优秀。只有3.3%的重建图像诊断质量不可接受。
OMAR可以有效减少脊柱内固定患者的金属伪影,获得具有高度诊断性的3DCT重建图像。
