New imaging techniques help to better understand the pathophysiology of entheses, being one of the essential factors of the subclinical and prodromal stages of psoriatic arthritis. This paper aims to review the main clinical scores, imaging scores, confounding factors that might influence the interpretation of results and the impact of medication on enthesitis in psoriatic arthritis.
