Weightbearing Digital Tomosynthesis of Foot and Ankle Arthritis: Comparison With Radiography and Simulated Weightbearing CT in a Prospective Study

摘要

OBJECTIVE. Foot and ankle arthritis is common and debilitating. Weightbearing radiography is the reference standard for evaluating alignment, but overlapping bones and hardware limit evaluation for osteoarthritic bony detail. The purpose of this study was to evaluate whether digital tomosynthesis (DTS) can yield reliable quantitative alignment values, as radiography does with its weightbearing capability, and good qualitative osteoarthritic detail, as CT does.
