Title: Diffusion-weighted imaging studies for hepatocellular carcinomas
Abstract: Objective To explore the application value of diffusion-weighted imaging(DWI)in hepatocellular carcinoma(HCC)diagnosis.Methods Thirty-eight patients with HCCs had undergone preoperative liver conventional magnetic resonance imaging(MRI),and the apparent diffusion coefficient(ADC)was obtained.The ADC values of tumors and normal liver tissues were measured on DWI images by one radiologist,and their differences were analyzed.Results All 38HCCs showed high signal intensity on the diffusion-weighted images.The mean ADC values of the HCCs and normal liver tissues were 1.15±0.51and 1.61±0.73×10-3mm2/s,respectively.The ADC values of the HCCs were significantly lower than those of normal liver tissues(p=0.000).Conclusion The ADC values of the HCCs and the normal liver tissues were significantly different,which may be useful in the diagnosis of hepatic lesions.
