Intended for practising rheumatologists, this book will also be useful for postgraduate students and internists with an interest in rheumatology. It familiarises clinicians involved in the care of patients with spondyloarthritis (SpA) with various common and uncommon imaging features of these disorders. In addition, it will serve as a reference for comparison of imaging features observed by clinicians in their day-to-day practice. The purpose is to make it easier for a rheumatologist to understand the report given by a radiologist in this context and to participate with a basic understanding during multidisciplinary meetings involving radiology colleagues. The aim is to ensure better patient care through shared understanding of imaging findings. Detailed illustrations and explanation of various imaging findings in patients with spondyloarthritis. Basic science of MRI and its sequences have been explained in a simple language which rheumatologists and internists can understand. Various uncommon imaging features like entheseal inflammation and ligamentous ossification have been nicely illustrated. Provides a vivid collection of plain radiographs, MRIs and CT scans obtained during care of patients with spondyloarthritis. Both the axial and peripheral joints have been included.
