目的： 提高腹部疾病影像诊断水平， 探索动脉造影ＣＴ在腹部疾病诊断中的应用价值。对象与方法： ２２ 例腹部疾病患者行动脉造影ＣＴ检查， 检查后均经手术或活检明确诊断。常规血管造影操作将导管插入病变供血动脉后， 注入造影剂同时行ＣＴ扫描， 观察影像学改变， 做出诊断； 同时观察离子型造影剂和非离子型造影剂的差别。结果： 诊断符合率９５－５％ ， 离子型造影剂和非离子型造影剂之间在检查中未见差别。结论： 动脉造影ＣＴ对于腹部实质脏器肿瘤的定性诊断及消化道出血的诊断具有较大的临床应用价值。在动脉造影ＣＴ检查中使用离子型造影剂可以降低检查成本。
Objective: To improve the imaging diagnosis of abdominal diseases and to explore the value of arteriography CT in the diagnosis of abdominal diseases. Subjects and Methods: Twenty-two patients with abdominal diseases underwent arteriography CT examination. All patients underwent surgery or biopsy to confirm the diagnosis. Conventional angiography catheter inserted into the lesion feeding artery, while injecting contrast agent CT scan to observe the imaging changes to make a diagnosis; the same time, observe the difference between ionic contrast agent and non-ionic contrast agent. Results: The diagnostic coincidence rate of 95-5%, no difference between the ionic contrast agent and non-ionic contrast agent in the examination. Conclusion: Arteriography CT has great clinical value in the diagnosis of abdominal solid tumors and the diagnosis of gastrointestinal bleeding. The use of an ionic contrast agent in arteriography CT can reduce the cost of inspection.
