Foreword

This is the second issue of Seminars in Musculoskeletal Radiology concerned with imaging metabolic bone disease. The previous issue (Part 1) covered the background biochemistry and recent advances in imaging, and focused on the more common manifestations of osteomalacia and osteoporosis. This issue (Part 2) delves even further into this complicated topic with a discussion of recognized diseases such as drug-induced metabolic bone disorders, osteopetrosis, and hyperphosphatasia. Also included in Part 2 are contemporary articles on Paget's disease of bone and tumoral calcinosis. To advance the science of musculoskeletal imaging further, the issue concludes with a discussion of metabolic bone disease in animals, a subject not often presented to radiologists. As with the first issue, the guest editor, Judith Adams, has gathered an impressive list of authors and comprehensive topics. Our hats and derbies go out to all these authors and especially to Judith. Cheerio!
