【摘要】：目的探索卵巢静脉追踪结合多平面重组方法在CT识别卵巢中的应用价值。方法搜集行腹盆部CT增强扫描、随后进行手术并取得病理结果的女性盆腔肿物患者234例。两位放射科医师在CT静脉期图像上观察卵巢静脉的显影情况,将逐层连续显示的卵巢静脉视为显影良好。采用卵巢静脉追踪结合多平面重组方法识别卵巢。以手术及病理结果为金标准,计算该方法识别正常卵巢的敏感性、特异性、准确性。结果被观察病例234例,其中单侧附件切除术后3例,共465侧卵巢静脉中,显影良好459侧,卵巢静脉显影良好率98.7%。245侧正常卵巢中,CT识别正确224侧,220侧非正常卵巢中,CT识别正确215侧。采用卵巢静脉追踪结合MPR的方法,CT识别正常卵巢的敏感性、特异性、准确性分别为91.4%、97.7%、94.4%。结论 CT静脉期能够很好地显示卵巢静脉。采用卵巢静脉追踪结合多平面重组方法在CT上识别卵巢的准确性很高。这种方法在实际工作中有很大的应用价值,值得推广。
[Abstract]:Objective to explore the value of ovarian vein tracing combined with multiplanar recombination in ovarian identification by CT. Methods two hundred and four female patients with pelvic masses underwent abdominal and pelvic CT enhanced scanning followed by surgery and pathological results. The two radiologists observed the development of ovarian veins on CT images, and regarded the continuous display of ovarian veins as good. Ovarian vein tracing combined with multiplanar recombination was used to identify the ovary. The sensitivity, specificity and accuracy of this method for identifying normal ovaries were calculated according to the gold standard of surgical and pathological results. Results 234 cases were observed, including 3 cases after unilateral adnexectomy. 459 of 465 ovarian veins were well developed, and 98.7.245 of the normal ovaries were identified correctly by CT. Of 220 abnormal ovaries, CT identified 215 correctly. The sensitivity, specificity and accuracy of CT in identifying normal ovaries were 91.4 and 97.794. 4 respectively by using the method of ovarian vein tracing combined with MPR. Conclusion the ovarian vein can be well displayed in CT venous phase. Ovarian vein tracing combined with multiplanar recombination is highly accurate in identifying ovaries on CT. This method has great application value in practical work and is worth popularizing.
