Performance of a novel high-resolution infrared thermography marker in detecting and assessing joint inflammation: a comparison with joint ultrasound.

Objectives: To examine the value of a novel high-resolution thermographic marker in the detection of joint inflammation compared to joint ultrasound (US) and to suggest thermographic cut-off values of joint inflammatory activity.

Methods: Infrared thermographies were performed in patients with inflammatory arthritides and healthy controls. Patients were moreover examined clinically and by joint-US [Power-Doppler-(PDUS), Greyscale-US (GSUS)].
