Abstract
To specify the possibilities for application of the liver-specific contrast agent (gadoxetic acid) in MRI with diffusion-weighted images (DWI) in the diagnosis of hepatocellular carcinoma (HCC).
Results: On the basis of the data obtained, we identified a complex of semiotic features that allow the tumor to be correctly differentiated as a HCC, namely:
- hypointensity on T1-weighted images (р > 0.1)
- hyperintensity on DWI (р < 0.001)
- diffuse heterogeneous enhancement in the early phases (р < 0.001)
- hypointensity in the hepatobiliary phase (р = 0.013)
Conclusions: The complex of revealed semiotic features based on the combination of the liver-specific contrast agent (gadoxetic acid) in MRI with DWI makes it possible to reliably recognize the HCC among other neoplasms of the liver (sensitivity 100 %, specificity 91.7 %, accuracy 97.1 %).
