To investigate the diagnostic value of resistance index (RI) in differentiating focal liver lesions.
In this retrospective study, a total of 576 patients with histologically confirmed focal liver lesions were included. Each patient underwent B-mode ultrasound examination and color Doppler ultrasound examination. The RI values of different focal liver lesions were recorded and compared.
The mean RI value of benign lesions was significantly lower than that of malignant lesions (0.54 ± 0.10
Color Doppler ultrasound examination is a valuable imaging method in detecting blood flow signal within liver lesions. The RI parameter should be helpful in differentiating malignant and benign liver tumors.
