A total of 31 patients with diverticulitis were analyzed who had both computed tomography and contrast enema. There was almost equal sensitivity to abnormality of approximately 90 percent. Contrast enema produced a specific diagnosis of diverticulitis in 61 percent, using stringent positive criteria, and an additional 29 percent with suggestive findings. Comparative computed tomography specific diagnoses in those 31 cases was made in 65 percent, and suggestive in 23 percent. Computed tomography was particularly useful diagnostically in cases of retrograde obstruction on contrast enema. The authors conclude that contrast enema should be the primary mode of approach, while computed tomography can be a valuable follow-up when the diagnosis is still in doubt, or if it is possible that patient management might be altered by additional information.
对31例同时接受计算机断层扫描（CT）和钡剂灌肠的憩室炎患者进行了分析。两者对异常情况的敏感性几乎相同，约为90%。按照严格的阳性标准，钡剂灌肠对憩室炎的确诊率为61%，另有29%的病例有提示性发现。在这31例病例中，CT的确诊率为65%，提示性诊断率为23%。在钡剂灌肠出现逆行性梗阻的病例中，CT在诊断上特别有用。作者得出结论，钡剂灌肠应作为主要的检查方法，而当诊断仍有疑问，或者额外信息可能改变患者治疗方案时，CT可作为有价值的后续检查手段。
