Gmtrast-enhanced CDFI in the Diagnosis of Focal Hepatic Lesions

Objective: To evaluate diagnosis value of contrast-enhanced CDFI in focal hepatic lesions. Methods; Seventy-five patients with hepatic lesions (including 18 benign lesions and 57 malignant ones) were examined with Contrast-enhanced CDFI (ECDFI). The findings on color Doppler sonograms of each lesion were correlated with CT findings, to compare the ability of blood flow detection and accuracy of diagnosis of both modalities. Results: The blood flow detection rate of ECDFI and CT was78% and 83% in the benign lesions, those in the hepatic carcinoma cases were 96% and 98%. The accuracy of diagnosis of ECDFI and CT were 93% and 87%. Conclusion:Contrast-enhanced CDFI sonography increases the detection rate of blood flow signal and accuracy of diagnosis, the sensitivity and specificity are well correspondent with CT. Enhanced CDFI is helpful for making correct diagnosis in the suspected cases in which CT reveals untypical evidence of liver lesions, and vice versa.
