摘要 目的探讨宫颈癌的多普勒超声学特征,并分析其与病灶内微血管密度(MVD)的相关性。方法选取50例宫颈癌患者为研究对象,均接受彩色多普勒超声检查。观察不同分期宫颈癌多普勒超声学特征,并分析宫颈癌特征与MVD的相关性。结果Ⅰ期病变宫颈形态正常或轻度增厚,宫颈内回声略增强,存在点状血流信号。Ⅱ期病变宫颈体积增大,不均匀增厚,内回声不均,存在点状、条形或者网状血流信号。Ⅲ期病变则存在宫颈外浸润。不同组织类型间多普勒超声RI值及MVD值间比较均无统计学差异。伴有淋巴结转移者RI值显著低于无淋巴结转移者,MVD值显著高于无淋巴结转移者,差异均具有统计学意义(P<0.05)。随着宫颈癌分期的增加,其RI值逐渐降低,MVD值逐渐升高,组间比较,差异均具有统计学意义(P<0.05)。Pearson相关分析显示宫颈癌RI值与MVD值间呈显著负相关(r=-0.506,P=0.011)。结论多普勒超声可以显示宫颈癌特征,且宫颈癌RI值与MVD值间呈显著负相关。
