PDFAbstract
Objective To discuss and analyze the value of magnetic resonance diffusion weighted imaging in the diagnosis of benign and malignant liver lesions. Methods 120 cases with hepatic lesions were (232 lesions) underwent 1.5T MRI scanning. Different b values were selected to exert DWI and high-resolution T2WI, and ADC values were measured. Results Differences of ADC values among various liver lesions had statistical significance (P<0.05) by low b value; Differences of ADC values between benign and malignant liver lesions had statistical significance (P<0.05) by medium and high b value; Differences of ADC values between liver cancer and liver metastatic tumor and healthy liver had statistical significance (P<0.05) by high b value. Conclusion Lesions can be clearly diagnosed by comparing the characteristics of DWI images and different range of ADC value, and DWI has great value in the diagnosis of liver occupying lesions, and the tumor / liver ratio has certain value in the differential diagnosis of primary liver cancer and liver metastatic tumor.
