Case-based and problem-based learning are rapidly being adopted in professional programs in medicine, business, law, engineering, and technology. As a student and a teacher for more than 50 years I know case studies are the most effective way of learning. A case will allow the reader to address more than one goal at a time. I have always been more intrigued and stimulated by studying and analyzing an interesting case than by reading a general topic about a subject. Studying a case is like reading a true story; it stimulates your curiosity and makes you think. In choosing a good case one should consider the importance of the potential learning issue. Is it central to the diagnosis, or is the case too difficult or too mundane or just right? Is it relevant for everyday practice or so bizarre that no one really cares about it? Is the case open-ended enough to stimulate the reader to go beyond fact finding?
Is the text relevant to the case; is it too short or too long? Does it provide pertinent differential diagnosis? Does it tell you how to distinguish this condition from other conditions that may present similarly or masquerade the same appearance? Does the text provide you with pearls or the highlight of current literature about this condition? And finally are the findings in the main case and differential diagnosis well illustrated and present superb image quality? The objective of this book is to provide the above points and present a comprehensive collection of cases that are relevant and constitute the core of knowledge that a musculoskeletal radiologist must know. The thrust of this book is to present interesting and relevant cases using advance imaging modalities such MRI, CT, US, and scintigraphy. What makes this book unique is that over 70 contributors from the United States and different corners of the globe have contributed to the pool of the cases presented here. Coverage begins with conditions of the shoulder and ends with ankle and foot and finally spine and miscellaneous cases.
