目的 探讨人工气腹造影CT操作方法及技术要点,为临床规范化应用提供依据。方法 收集2013-01至2019-11行人工气腹CT造影检查的患者331例,均行规范化人工气腹造影后对患者腹部进行平卧位,左、右侧卧位及俯卧位CT薄层扫描并三维重建。结果 331例患者均能较好地显示腹腔内脏器与腹膜之间的关系,其中影像诊断结果中正常43例,异常288例,术后结果中正常28例,异常303例,经Kappa一致性检验,气腹造影CT诊断结果与手术结果具有高度的一致性(kappa=0.765,P<0.05)。结论 人工气腹造影CT技术方法安全可靠,实用性高,熟练掌握可获得较好的显影效果,为腹腔内疾病诊断尤其是腹腔内粘连提供了很好的影像学依据。

Objective Objective To explore the operation methods and essential technology of artificial pneumoperitoneum CT in order to provide reference for standardized applications. Methods A total of 331 patients who underwent artificial pneumoperitoneum CT angiography between January 1, 2013 and November 1, 2019 were collected. All of them underwent standardized artificial pneumoperitoneum angiography of the abdomen in the horizontal position, left and right lateral position, and prone position within CT thin layer scan and 3D reconstruction. Results The relationship between abdominal organs and the peritoneum was clearly shown in each of the 331 cases. According to results of imaging diagnosis, 43 cases were normal and 288 were abnormal. Based on postoperative results, 28 were normal and 303 were abnormal. Kappa consistency test showed that the imaging diagnosis of the CT scan of artificial pneumoperitoneum was quite consistent with surgical results (kappa=0.765, P<0.05). Conclusions The technology of artificial pneumoperitoneum CT is safe, reliable, and practical. Proficiency can lead to good imaging results. This technology can provide useful imaging data for the diagnosis of intra-abdominal diseases, especially intra-abdominal adhesions.
