螺旋CT多期增强扫描在Ⅱa-Ⅱb期宫颈癌诊断中的应用

Application Value of Spiral CT Multi-phase Enhanced Scan in the Staging of Ⅱ a-Ⅱ b CervicalCancer

【目的】探讨螺旋CT多期扫描在宫颈癌Ⅱa-Ⅱb分期中的价值。【方法】对28例经病理证实的宫颈癌患者行螺旋CT增强扫描，所有病例均分别行注药完后40-50S及90-180S两期或三期扫描，并与手术分期对照。[结果]CT分期结果和手术判断结果一致者21例，占75％，不一致者7例，占25％，其中分期过低2例，占7．1％，分期过高5例，占17．9％。【结论】螺旋CT多期增强扫描可明显提高宫颈癌Ⅱa-Ⅱb分期的准确性，对宫颈癌临床治疗提供有力依据。

[Objective] To explore the value of multi-phase spiral CT scan in the staging of Ⅱa-Ⅱ b cervical cancer. [Methods]Twenty eight cases of cervical cancer confirmed by pathology received spiral CT contrast enhancement scan. All patients received two or three-stage scan with 40-50 seconds and 90- 180 seconds after injection, respectively, and were compared with surgical-pathologic staging. [Results] The results of CT staging and surgical results were coincident in 21 cases, accounting for 75%, and were inconsistent in 7 cases, accounting for 25 %, including 2 cases with too low stage, accounting for 7.1 %, and 5 cases with high stage, accounting for 17.9 %. [Conclusion] Spiral CT multi-phase enhanced scan can improve significantly the accuracy of the staging of Ⅱ a- Ⅱ b cervical cancer and provide helpful evidence in clinical treatment.
