【摘要】 目的确定数字化X线摄影(DR)对探测肋骨骨折的优势。方法 100例临床高度怀疑肋骨骨折患者(男43例,女57例,年龄28～76岁,平均54岁)均经胸部DR检查。摄影操作包括进行常规肋骨双斜位拍摄,采用自动程序曝光,运用窗口技术显示肋骨骨折的部位、数量。结果在100例患者中,DR检出76例肋骨骨折,其中,单纯骨折75例(单发23例,多发52例)和肋骨骨折并发气胸1例。12例原始图像未见明显骨折的患者,其中包括5例膈下肋骨骨折和7例无错位的不完全性肋骨骨折,通过DR图像后处理系统调节图像的窗位窗宽,骨折的征象明确显示。结论 DR在探测肋骨骨折,尤其是对无错位的不完全骨折,具有明显优势,可作为首选方法。更多还原

【Abstract】 Objective To determine the advantage of digital radiography(DR) for detecting the rib fractures.Methods A hundred patients(43 men,57 women;aged 28-76 years;mean age,54 years) with highly suspected rib fracture underwent DR examinations of the chest.The procedures included using routine double-oblique position photography of the ribs,automatic programme exposure and window technique to visualize the location and number of rib fractures.Results Among 100 patients,DR detected 76 rib fractures which comprised 75 simple fractures(23 single and 52 multiple) and 1 rib fracture associated with pneumothorax.Through image postprocessing reconstruction and window techaique regultation,DR demonstrated 12 cases of occult rib fractures not visible on the original images,who comprised 5 subphrenic and 7 non-dislocated and incomplete rib fractures.Conclusion DR in detecting rib fractures,especially non-dislocated and incomplete fractures,has significant advantage so that it should be taken as a first choice modality.更多还原
