摘要
目的探讨彩色血管能量成像(CPA)在卵巢肿瘤诊断中的应用价值。方法95例患者105个病灶经CPA成像,对肿块内的血液供应情况进行分级,并用脉冲多普勒探测肿块血流的阻力指数(RI),良恶性肿块进行比较。结果以RI≤0.5为标准诊断卵巢恶性肿瘤的敏感性和特异性分别为93%、97%。以血流分Ⅲ级为标准诊断卵巢癌敏感性,特异性分别为57%、100%。以血流Ⅰ级为标准诊断良性肿瘤的敏感性,特异性分别为74%、91%。结论CPA肿块的血流分级和RI联合应用,有助于卵巢肿块的诊断和鉴别诊断。
Objective To evaluate the value of power anglo imaging （CPA） in the diagnosis of ovarian neoplasms.Methotis Ninty five patients with one hundred and five ovarian tumore were examined preoperatively by CPA sonography, and ovarian tumors wrer classified into three grades according to the umor vascularty. Resistance index（RI） was measured with pulsed Doppler sonography. The differences between bening and malignant tumors were compared. Results The cutoff of RI≤0.5 with the highest accuracy had a sensitivity of 93% specificity 97% .The authors diagnosed malignancy with vas cularity do the third grade,which had a sensitivity of 57% and specificity of 100% .The authors disgnosed benignity with vascularity of the first grade, with had a sensiticity of 74% and specificity of 91%. Conclusion The conmbination of grades of vascularity in CPA and RI can br helpful to the diagnosis of the ovarian neoplasms.
