Abstract：The metal artifacts generated by the metal implants in the body will cover the anatomical structure and reduce the diagnostic accuracy in the postoperative review.Dual-energy CT virtual monoenergetic imaging combined with MAR technology can effectively reduce the influence of metal artifacts on CT image quality,but the optimal monoenergetic level for suppressing metal artifacts in different parts is different.Therefore,this article reviews the current research status of the optimal monochromatic energy levels for reducing metal artifacts in different locations,including intracranial aneurysm embolization,oral metal implants,spinal internal fixation,hip replacement,and other implants.This review aims to provide a scientific basis for clinical imaging practice,thereby optimizing imaging parameters and improving the accuracy of postoperative evaluation.
