In recent years the scientific community has shown renewed interest in DISH. The article by Yaniv et al. [1] in this issue of Rheumatology describes the natural evolution of DISH, providing important new insights into this condition. The article presents a study that used CT, a highly sensitive three-dimensional imaging modality for assessing new bone formation, to identify DISH patients and ex...
