Metal artefact reduction algorithm for correction of bone biopsy needle artefact in paediatric C-arm CT images: a qualitative and quantitative assessment

• Evaluation of Metal Artefact Reduction algorithm for C-arm CT biopsy needle artefact.
• MAR-corrected images demonstrated improved image quality.
• Significant image-noise reduction observed in the needle vicinity in patient group.
• MAR algorithm provides better visualization of needle and surrounding soft tissue.
• MAR can potentially improve physician's confidence in needle tip placement.
