[Abstract] Objective: Comparison of susceptibility weighted imaging and dynamic contrast-enhanced MR imaging in the diagnosis of small hepatocellular carcinoma and to explore the clinical application value of SWI in small hepatocellular carcinoma.Materials and Methods: SWI and dynamic contrast-enhanced MR imaging were performed on 60 patients with small hepatocellular carcinoma, And an independent diagnosis was made by three high-year-funded diagnostic radiology doctors, and The results were compared and analyzed statistically. Double blind method was used in this study.Results: In 60 cases of small hepatocellular carcinoma, 48 cases were positive by SWI scan, 12 cases were negative, 50 cases were positive by MRI scan, 10 cases were negative. Statistical analysis showed that there was no significant difference between the two scanning methods in the diagnosis of small hepatocellular carcinoma (P<0.05).Conclusions: This study found that MRI enhanced scanning in the diagnosis of small hepatocellular carcinoma was a routine clinical application and high reliability of diagnostic methods, SWI scan could be used as a supplementary sequence of MRI enhanced scan. SWI was used to dynamically track the change of hepatic cirrhosis nodules, which has important clinical value in the early diagnosis of HCC. However, the MRI enhancement scan of small hepatocellular carcinoma could not be replaced.
