Assessment of Wrist Joint and Knee Joint Inflammation in Patients With Rheumatoid Arthritis by Quantitative Three Dimensional Power Doppler Ultrasonography

Taichung Veterans General Hospital49 enrolled

Overview

The purpose of this study is to: 1. To investigate the wrist joint synovial blood flow intensity and model by quantitative three-dimensional (3D) power Doppler ultrasonography (PDUS) in patients with rheumatoid arthritis before and after initiation of a new medicine and compare these data with routinely used clinical data and laboratory findings, such as pain score, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) 2. To investigate the intra-observer and inter-observer agreement of quantitative 3D PDUS assessment of the vascularity in wrist joints and knee joints using automatic volume scan.
