摘 要:本研究探讨了彩色多普勒(TVCDU)、三维彩色能量成像(3D-CPA)联合脉冲多普勒(PW)鉴别卵巢占位病变性质及对恶性病变术前分期的评估价值。选取卵巢占位病变患者110例,其中恶性肿瘤49例、良性肿瘤61例,均给予彩色多普勒超声检查。恶性肿瘤患者的肿瘤血管收缩期峰值流速(PSV)和血管指数(VI)明显高于良性肿瘤患者,而阻力指数(RI)明显低于良性肿瘤(P<0.05)。恶性肿瘤血管分级Ⅲ级比例明显高于良性肿瘤,而Ⅰ级比例明显少于良性肿瘤(P<0.05)。恶性肿瘤患者中,FIGO分期Ⅲ期患者的VI和血管分级Ⅲ级比例明显高于Ⅰ~Ⅱ患者(P<0.05)。RI、VI、血管分级及联合诊断恶性肿瘤的ROC曲线下面积分别为0.794、0.774、0.937和0.966;VI、血管分级及联合诊断恶性肿瘤FIGO分期Ⅲ期的ROC曲线下面积分别为0.810、0.691和0.955。由此可知,TVCDU、3D-CPA联合PW在鉴别卵巢占位病变性质及恶性病变术前分期评估中有较好的应用价值。The aim of this paper was to investigate the value of transvaginal color Doppler ultrasonography(TVCDU),three-dimensional color power angiography(3D-CPA)combined with pulse wave Doppler(PW)in the differential diagnosis of ovarian space-occupying lesions and the evaluation of preoperative staging of malignant lesions.There were 110 patients with ovarian space-occupying lesions who were selected and examined by color Doppler ultrasound,among whom 49 cases were malignant,61 cases were benign.The peak systolic velocity(PSV)and vascular index(VI)of malignant tumors were significantly higher than those of benign tumors(P<0.05),while resistance index(RI)was significantly lower than that of benign tumors(P<0.05).The proportion of vascular gradeⅢof malignant tumors was significantly higher than that of benign tumors(P<0.05),while the proportion of gradeⅠwas significantly less than that of benign tumors(P<0.05).The proportion of VI and vascular gradeⅢin stageⅢpatients was significantly higher than that of patientsⅠ-Ⅱ(P<0.05).The area under ROC curve of RI,VI,vascular classification and combined diagnosis on malignant tumor were 0.794,0.774,0.937 and 0.966,respectively.The area under the ROC curve of VI,vascular grading and combined diagnosis of malignant tumor FIGO stageⅢwere 0.810,0.691 and 0.955.In conclusion,TVCDU and 3D-CPA combined with PW have good application value in differentiating the nature of ovarian mass lesions and preoperative staging assessment of malignant lesions.
