Inter- and Intra-rater Agreement of Dermatologic Ultrasound for the Diagnosis of Lobular and Septal Panniculitis.

This study supports the use of US for diagnosing panniculitis. For subtyping panniculitis, the intra-rater correlation was good. Improvement of inter-rater agreement may depend on access to clinical information, dynamic images, a better definition of criteria, homogeneous configurations of the devices, and the expertise of dermatologic US operators.
