作者回顾1993年～1996年进行非增强螺旋CT扫描的178例急性胁肋部疼痛病人的放射学检查结果,他们在CT检查之前均进行过腹部平片检查。其中有79例CT扫描发现输尿管结石。应用三种方法对腹部平片进行评价:①原始诊断。即在CT检查之前病人的平片报告结果。②盲目性回顾性诊断。每一张平片的诊断都是在没有CT结果的 The authors reviewed the radiographic findings of 178 patients with acute rib pain who underwent non-enhanced helical CT scans from 1993 to 1996 who underwent a plain radiograph before the CT scan. Among them, 79 cases of ureteral calculi were found on CT scan. Application of three methods of evaluation of abdominal plain film: ① original diagnosis. That is, the plain film of the patient before the CT examination reports the result. ② blindness retrospective diagnosis. The diagnosis of each plain film is in the absence of CT results
