Objective:

To observe the real-time contrast-enhanced ultrasound (CEUS) findings of focal liver lesions and to evaluate the value of CEUS in the qualitative diagnosis of focal liver lesions.

Methods:

The results of real-time CEUS in 62 lesions of 50 patients with focal liver lesions were analyzed retrospectively. The sonographic features of CEUS were analyzed.

Results:

According to the diagnostic results of puncture pathology

the diagnostic coincidence rate of 62 focal hepatic lesions detected by CEUS was as follows: hepatocellular carcinoma (HCC) 85.7%

hepatic cholangiocarcinoma (CC) 100.0%

metastatic hepatic carcinoma (MLC) 100.0%

hepatic hemangioma 94.1%

focal nodular hyperplasia (FNH) 92.3%

cirrhotic nodule 100.0%

focal fat defect of liver 100.0%

local inflammatory lesions of the liver 100.0%. One HCC was misdiagnosed as hepatic hemangioma

one hepatic hemangioma and one FNH of the liver were misdiagnosed as HCC. The starting time of enhancement of malignant lesions was earlier than that of benign lesions

and the difference was statistically significant (

P

＜0.05). The peak time and time to begin to fade of malignant lesions was significantly earlier than benign lesions and the duration was significantly less than that in the benign lesions (

P

＜0.01). The majority of benign and malignant focal lesions in the liver have typical enhancement patterns.

Conclusion:

By providing the blood perfusion features of intrahepatic focal lesions

CEUS can clearly reflect the contrast-enhanced characteristics of different lesions. Therefore

CEUS has high accuracy and high application value in the differential diagnosis of benign and malignant lesions.
