[Abstract] Objective: To investigate the diagnostic value of contrast-enhanced magnetic resonance imaging (CE-MRI) combined with diffusion weighted imaging (DWI) in the diagnosis of atypical liver abscess and liver metastases.Materials and Methods: Retrospective analysis from January to December 2019 in Binzhou People's Hospital, 12 cases of atypical liver abscess and 11 cases of liver metastatic tumor were finally enrolled into the group, with a total of 43 lesions, MRI plain scan, DWI sequence and MR enhanced scan were performed in all cases, and all cases were confirmed by histological or clinical follow-up. It was divided into two groups, CE-MRI and CE-MRI combined with DWI, and the signal characteristics and enhancement modes of the lesions were analyzed and compared. Apparent diffusion coefficient (ADC) values of cystic and solid components of atypical liver abscess and metastatic tumor were compared.Results: The accuracy of CE-MRI in the diagnosis of atypical liver abscess and liver metastasis was 68.42% and 66.67%, respectively, and the accuracy of CE-MRI combined with DWI in the diagnosis of atypical liver abscess and liver metastasis was 94.73% and 87.50%, respectively, which were both higher than that of CE-MRI alone. The ADC values of cystic components of atypical liver abscess and liver metastatic tumor were about (1.18±0.04)×10-3 mm2/s, (2.02±0.17)×10-3 mm2/s, P<0.01, showing statistical differences; The ADC values of solid components of liver abscess and liver metastasis were approximately (1.58±0.10)×10-3 mm2/s, (0.91±0.10)×10-3 mm2/s, P<0.01, with statistical differences.Conclusions: CE-MRI combined with DWI has more advantages in the diagnosis of atypical liver abscess and liver metastases.
