Region of interest analysis; by selecting regions with denuded areas can we detect greater amounts of change?

摘要

INTRODUCTION:Based on recent analyses, the measures of short-term responsiveness of MRI derived cartilage morphometry may not be as large as earlier studies had suggested. We examined if by selecting regions of interest with denuded cartilage, if the remaining cartilage within this region of interest was susceptible to greater rates of cartilage loss.
