Optimal combination periprosthetic vasculature visualization and metal artifact reduction by spectral computed tomography using virtual monoenergetic images in total hip arthroplasty

ConclusionEighty kiloelectron volts on VMIMAR, providing satisfactorily reduced metal artifacts and improved vascular visualization, can be an optimal recommended parameter of spectrum CT for the assessment of periprosthetic vasculature in THA patients.Critical relevance statementThe metal artifact is gradually reducing with increasing energy level; however, the vascular visualization is worsening. The vascular visualization is terrible above 100  keV, while the vessel is disturbed by artifacts below 70 keV. The best performance is found at 80 keV.Key points• VMIMAR can provide both reduced metal artifacts and improved vascular visualization.• Eighty kiloelectron volts on VMIMAR performs best in vascular visualization of total hip arthroplasty patients.• Energy spectrum CT is recommended for routine use in patients with total hip arthroplasty.Graphical Abstract
