Cervico-Occipital Joint (RX, CT): 158 Radiological Exercises for Students and Practitioners (Exercises in Radiological Diagnosis)

Like my first book of exercises in radiological diagnosis con­ cerning the vertebrae in adults, the first part of this book consists of an atlas of images ready for immanent reading. The images are numbered, each number corresponding to a case. The second part comprises the corresponding comments, critical interpretations, and drawings (using the same num­ bers as the corresponding radiographs in the first part). I hope that this second booklet will be as appreciated as was the first, which was published in four languages (Radio­ diagnosis of the Vertebrae in Adults. Springer, Berlin Hei­ delberg New York 1983). My own documentation having proved deficient in some fields, I had recourse to the didactic collections oimy collea­ gues, friends, and students. Special thanks are due to Prof. J. F. Bonneville, and to Drs. J. L. Dietemann, Y. Dirheimer, J. C. Dosch, and J. Vignaud.

In a simpler way, one can say that it is necessary to distinguish the signifiant, the signi£ie, the comment, the interpretation, and the radiobioclinical confrontation. The signifiant or character is a normal or pathological "characteris­ tic" part of the image.
