Computed tomography (CT) is effective in demonstrating abdominal abscesses and their relation to surrounding structures. The CT signs of abscess are not unlike those demonstrable radiographically and include an abnormal mass, obliteration and displacement of surrounding organs, inappropriate gas, and peripheral enhancement after intravenous contrast. Axial imaging permits selection of safe approaches through which percutaneous needle aspiration can be performed for diagnosis and therapy. When techniques similar to those employed in angiography are used, a catheter can be inserted, the abscess evacuated, and the catheter left in place as a drain. Combined with intravenous antibiotics, this method of abscess drainage has been successful in curing abscesses without surgery. Representative examples are shown.
计算机断层扫描（CT）在显示腹部脓肿及其与周围结构的关系方面很有效。脓肿的CT表现与X线摄影所见并无不同，包括异常肿块、周围器官的闭塞和移位、异常气体以及静脉注射造影剂后的周边强化。轴位成像有助于选择安全的穿刺路径，通过该路径可进行经皮穿刺抽吸以用于诊断和治疗。当采用与血管造影类似的技术时，可插入导管，排空脓肿，并将导管留置作为引流管。结合静脉使用抗生素，这种脓肿引流方法已成功治愈脓肿而无需手术。文中展示了典型病例。
