ABSTRACT



Aim of the Study: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.
Materials and Methods: 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.
Results: 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.
Conclusion: OMAR can effectively reduce metallic artifacts in patients with spinal instrumentation with highly diagnostic 3DCT reconstruction images.
Keywords: Orthopedic metal artifact reduction, spinal instrumentation, three-dimensional computed tomography
