Total hip endoprosthesis evaluation with MSHCT

Preoperative evaluation of remaining “bone stock” for revision arthroplasty in 61 year old woman.

MSHCT with thin slices minimizes the metal artifacts on axial scans. Despite the prostheses in both hips, the remaining bone can be evaluated on multiplanar reformats.
