　　①用词简洁、精确；
　　Results:Seven CT scans were interpreted as showing normal findings and 20 scans revealed intracranial pathology on both CT scanners.Image quality was higher on the fixed scanner(average rating2.42 pointsSE=0.12)than on the transportable scanner(average rating3.10 pointsSE=0.12(p=0.001).Depiction of the cerebellummidbrainand supratentorial gray? white matter was better on the fixed scanner(p＜0.05＝.Howeverwe found no significant differences in detection of intracranial pathology between scanners.Both radiologists found images from both scanners to bediagnostic in all 27 patients.　　Conclusion:Images of the brain on the transportable CT scanner were less clear than those on a fixed scanner.Howeverimages from the transportable CT scanner were diagnostic in 27 consecutivepatients.The implications of this finding are important for the provision of CT services for critically ill patients who cannot be transported to the radiology department.
　　④要领和功效中强调统计要领及数据。对母语非英语的作者来说，撰写英文摘要的质量优劣直接与作者的英文程度有关，在这方面，只有多阅读英文文献，才气提高英文写作程度，从而写出高质量的英文摘要。 　　③不消第一人称，多用被动语态；
　　英文摘要的字数大大都期刊划定不高出250个词，内容应与中文摘要对应。医学论文中，一般罕用第一人称和主动语态，多用第三人称和被动语态，用以浮现论述客观事实。所用时态需与工作产生时间一致，论述根基纪律时可用此刻时，论述研究工具、要领和功效时，用已往时。举譬喻下：
　　Objective:The purpose of this study was to determine whether an in hospital transportable CT scanner can provide diagnostic brain images and to compare the quality of these images with those from a convertional fixed? platform CT scanner.　　Subjects and Methods:Twenty seven patients with known or suspected intracranial pathology underwent imaging on a transportable scanner and a fixed? platform scanner within 1hr of each other.Images from each CT examination were evaluated independently by two neuroradiologists who were unaware of patient history.Conspicuousness of intracranial pathology and normal anatomy were rated on a 5? point scale (1 point optimal;5 pointspoor or not visualized).Statistical comparisons were made using nonparametric tests.
　　②时态为已往时；
　　上面是AJR(美国放射学杂志)中一段完整的英文摘要，从中可以看出其特点：
