This volume is the latest in the series Exercises in Radio logical Diagnosis, launched by the Strasbourg School of Radio logy. Further volumes on the facial bones, senology, and abdominal tomography are in preparation. Jean-Louis Dietemann has over a decade’s experience of radiodiagnosis of the skull, and has already proven his talents as a teacher with his earlier books on the sella turcica and on carotid angiography. The present volume will assuredly be a great success and will enhance the series. Professor A.
