Achilles tendon enthesitis is the source of the the heel pain of PsA patients. The current measures based on pressure being placed on various entheses during physical examination are both insensitive and non-specific.Also it’s very time consuming and poorly reproducible.MR imaging with ultrashort echo time (UTE) sequences provides a good option for assessing entheses, which has a relatively short T2 and largely “invisible” with clinical MR sequence.
