The new millennium and right on schedule comes thefourth edition of Diagnosis of Bone and Joint orders.This， then， is the third time I have revised this text sinceits initial publication in 1981， more than 2 decades ago.Each time I have begun work on a new edition， I be-lieved incorrectly that my job would be easier because，I thought， how much information could possibly havebeen introduced in the 5 or 6 years that had elapsedsince the previous edition？ And each time， without ex-ception， I have been surprised by the progress that hasoccurred with regard to the further understanding andimproved diagnostic assessment of the many diseasesthat affect the musculoskeletal system. So now， 7 yearsafter the publication of the third edition， the fourthedition is offered as clear evidence that much has beenlearned， new concepts have emerged， and "old facts"have been modified or eliminated altogether. I am often asked at the time of publication of a newedition precisely how much of the material is appearingfor the first time. This is a difficult question to answerquantitatively. My educated guess is that 30 per cent ofthe information is new or has been modified significantlyfrom that contained in the third edition， that the number of references has been expanded by 25 to 35 per cent （with emphasis given to pertinent recent publications）， and that new illustrations represent 25 to 30 per cent of the total number appearing in this edition. With regard to the illustrative material， the new figures underscore the increasing importance of MR imaging as a vehicle for investigation of these diseases.The size of the fourth edition does not differ signifi- cantly from that of the last edition， although the number of volumes has been decreased by one. （You will note that each is somewhat heavier than in the past！） To be certain that this multivolume book did not become too large， I consulted extensively with the following changes.

随着影像诊断技术的飞速发展，磁共振成像（MRI）技术及X线CT在脊柱及脊髓疾病的临床诊断中发挥了日益重要的作用。我们根据自己的临床经验，参阅国内外有关文献资料，编写了《脊柱和脊髓疾病影像诊断学》一书。该书除简要介绍相关临床、病理、普通X线、DSA、脊髓造影表现外，着重系统论述了脊柱、脊髓疾病的CT和MRI影像特征、诊断与鉴别诊断。在编写过程中强调理论与实践经验并重，图文并茂、重点突出，力求给读者留下较全面、深刻的印象和概念。全书分19章，共有图片357组，其中线条图近百张，影像图片600余张。全书采用我院近10年来的教学及日常临床工作积累。本书可作为影像诊断学医师、脊柱外科、神经内科临床医师和研究生日常工作、学习的参考用书。

颅氏疾病的诊断和治疗是颅底外科学的重要组成部分，鉴于颅底外科的迅猛发展，《颅底疾病诊断与治疗》作者集神经外科和五官科多年临床实践经验，参考国内外新近文献，对颅底疾病诊断和治疗作了系统、全面的阐述，包括颅底应用解剖，颅底疾病的外科基础，麻醉监测，手术基本入路，颅底肿瘤，骨性、感染性、外伤性、先天性、血管性、功能性疾病的临床诊治以及颅底重建等。《颅底疾病诊断与治疗》取材广泛，内容丰富，具有很强的实用性。是一本神经外科、五官科等医师学习和参考必备的专业书籍。
