彩色多普勒超声检查对经典型肝局灶结节增生的诊断价值

The diagnosis value of classic liver focal nodular hyperplasia by color Doppler ultrasonography

目的探讨彩色多普勒超声检查对经典型肝局灶结节增生的诊断价值。方法对43例48个经手术病理证实的肝局灶结节增生进行彩色多普勒超声检查,根据有无中心血流分为经典型与非经典型。将超声分型与病理分型进行对照研究。结果 48例肝局灶结节增生病理诊断为经典型36例,其中彩色多普勒超声检查检出中心血流27例。彩色多普勒超声检查对经典型肝局灶结节增生敏感度、特异度、阳性预测值、阴性预测值、诊断准确率分别为75.0%、91.7%、96.4%、55.0%、79.2%。结论彩色多普勒超声对经典型肝局灶结节增生诊断特异性较高,诊断可靠,敏感性略低,尚有部分病例超声检查不能显示中心血管,需进一步检查。

Objective To assess the diagnostic value of color Doppler sonography for patients with classic liver focal nodular hyperplasia（FNH）.Methods A total of 43 patients with 48 tumors（all proved as FNH by pathology） were scanned by color Doppler ultrasonography.According to the finding of central vessel of tumor,the FNHs were classified into classic and nonclassic.The outcomes were compared with those of histological typing.Results Thirty-six tumors were classic FNHs diagnosed by histology and 27 cases of central vessel were detected by color Doppler ultrasonography.The sensitivity,specificity,positive predictive value,negative predictive value,accuracy of color Doppler ultrasonography for classic FNH were 75.0%,91.7%,96.4%,55.0% and 79.2%,respectively.Conclusion The low spceificity of color Doppler ultrasonography for classic FNHs was found,which demonstrated the image method or biopsy should be still needed.
