摘要: Objective The aim of this study was to evaluate the usefulness hypothetical monoenergetic images after dual-energy computed tomography (DECT) for assessment bone encircling dental implant bodies. Study design Seventy-two axial implantation sites clipped out from image data scanned using DECT in mode were used. Subjective on reduction dark-band-like artifacts (R-DBAs) and diagnosability adjacent condition (D-ABC) 3 sets images—a fused set (DE120) 2 (ME100, ME190)—was performed results statistically analyzed. Results With regards R-DBAs D-ABC, significant differences among DE120, ME100, ME190 observed. ME100 revealed more artifact than those DE120. Conclusions imaging followed by construction can cause increase D-ABC may be potentially used evaluation postoperative changes
