The value of compression and/or invasion signs in ultrasonic diagnosis of minimal hepatic tumors
Abstract：Objective To investigate the value of compression and /or invasion signs in ultrasonic diagnosis of minimal benign and malignant hepatic tumors.Methods 178 hepatic lesions less than 2.0 cm in 164 cases proved by puncture or operation pathology were examed by the dimensional ultrasonography and color Doppler flow.The com-pression and /or invasion signs were regarded as a criterion of malignant hepatic tumors.Results The detection rate of compression and /or invasion signs in the malignant hepatic minimal lesions(75.24%,79/105) was much higher than that in the benign hepatic minimal lesions(4.11%,3/73)(P<0.05).The sensitivity, specificity and accuracy of the ultrasound in the diagnosis of malignant hepatic minimal tumors were 75.24%, 95.89%and 83.71%respec-tively.The Kappa was 0.679, and the area of ROC was 0.846(95%CI=0.786~0.906) .Conclusion The param-eters of compression and /or invasion signs in ultrasonography can be used for the differential diagnosis of benign and malignant hepatic minimal lesions.
