腹部螺旋计算机断层扫描 (CT) 肺炎是在清洁结肠后使用平滑肌松弛剂和直肠吹气进行的。使用静脉造影剂进行快速动态扫描，以提供最佳的肝脏和血管增强效果，以及 5-10 毫米的连续切片。每2.5毫米重建结肠中的感兴趣区域。该技术在4名结直肠癌患者中进行，并将CT结果与手术切除后的钡剂灌肠和病理结果进行比较，螺旋CT气结肠清楚地显示所有病例的原发肿瘤为增强的软组织肿块，并且能够检测局部扩展和淋巴结肿大以及评估肝脏、腹膜和剩余腹部，CT比钡剂更清楚地描绘原发肿瘤的形态灌肠，在一个病例中还发现了 1 厘米的息肉，但在钡剂检查中未发现该息肉，因为该患者因钡剂失禁且视野有限。 CT 与病理结果之间具有良好的相关性。与钡剂灌肠相比，螺旋 CT 气结肠速度快，患者不适感最小，无钡剂失禁风险，对局部和远处腹部疾病有良好的评估，可以进行多平面格式化，3D 重建可提供腔内和腔外视图。
Abdominal spiral computed tomography (CT) pneumocolon is performed after cleansing the colon, using a smooth muscle relaxant and rectal air insufflation. Rapid dynamic scanning is undertaken with intravenous contrast to give optimal hepatic and vascular enhancement, and 5-10 mm contiguous slices. The area of interest in the colon is reconstructed every 2.5 mm.This technique was performed in four patients with colorectal cancer and the CT findings were compared with the barium enema and pathology following surgical resection, Spiral CT pneumocolon clearly showed the primary tumour in all eases as an enhancing soft tissue mass, and,vas able to detect local extension and lymphadenopathy as well as assess the liver, peritoneum and remaining abdomen, CT depicted the morphology of the primary tumour more clearly than barium enema, and in one case also detected a 1 cm polyp which was not seen on the barium study because the patient was incontinent of barium and views were limited. There was good correlation between the CT and pathological findings.Compared to a barium enema, spiral CT pneumocolon is quick, with minimal patient discomfort, no risk of barium incontinence, and there is good assessment of the local and distant abdominal disease, Multiplanar formatting is possible and 3-D reconstruction gives intra- and extra-luminal views.
