Abstract Objective To investigate the imaging characteristics of 3.0T magnetic resonance imaging (MRI), diffusion weighted imaging (DWI), and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in the clinical diagnosis of patients with liver cancer. Methods A total of 94 patients with liver cancer diagnosed pathologically in Huaibei People’s Hospital of Anhui Province from February 2018 to October 2021 were analyzed, the MRI, DWI, and DCE examination data of patients at the time of admission were collected for analysis, and T1WI and T2WI signals, DWI signals and DCE images of diseased liver area and normal liver area, the apparent diffusion coefficient (ADC) of patient’s diseased liver area and normal liver area were calculated and compared. Results T1WI and T2WI signals of patient’s normal liver tissue showed equal signal levels, while DWI signal showed a lower level; T1WI signal of diseased liver area showed low signal level, and T2WI signal of diseased liver area showed equal signal or a little high signal level, and DWI signal presents a significantly high signal level. The average ADC value in diseased liver area was lower than that in normal liver area, and the difference was statistically significant (P < 0.05). Conclusion MRI, DWI, and DCE examinations of patients with liver cancer all show independent imaging characteristics, and the combined application in clinical practice can effectively improve the accuracy of pre-imaging diagnosis, and the calculation of ADC value at the same time has a certain value for judging the biological characteristics of the lesion area of patients with liver cancer.
