Signs in Musculoskeletal Radiology

Radiology is considered as becoming an original and important field of modern art. Indicative signs are useful to recognize pathologies and to narrow the list of differential diagnoses. In orthopaedics, many radiologic findings are named for the natural p

Foreword: Imaging Signs

Radiologic and radiographic “imaging signs” are critical to our quick recognition of disease states and instituting therapy. They are also perhaps even more vital to the teaching element for trainees, since such prompt recognition of an abnormal imaging pattern cements the appearance in the memory of the learner for future recognition. The goal of proposing such “signs” is that eventually a particular disease state’s radiologic appearance ultimately becomes accepted as a classic “imaging sign,” and thus gains recognition among radiologists and other subspecialists for general use. While it is acknowledged that a disease state does not absolutely have to exhibit the classic imaging sign (e.g., the “Rigler sign” of pneumoperitoneum), it is quite important to note such a sign, when present, as early as possible, in order to alert the ordering provider to a preventable complications of the disease state. The editors, Drs. Gao and McKinney et al., organized this text in a very practical fashion that can serve as a quick reference to enhance the reader’s understanding of each imaging sign, regardless of their level of trainin
