Trabecular bone analysis: ultra-high-resolution CT goes far beyond high-resolution CT and gets closer to micro-CT (a study using Canon Medical CT devices).

Abstract

OBJECTIVE: High-resolution CT (HR-CT) cannot image trabecular bone due to insufficient spatial resolution. Ultra-high-resolution CT may be a valuable alternative. We aimed to describe the accuracy of Canon Medical HR, super-high-resolution (SHR), and ultra-high-resolution (UHR)-CT in measuring trabecular bone microarchitectural parameters using micro-CT as a reference.
