Возможности МРТ с гепатотропным контрастным препаратом в диагностике гепатоцеллюлярного рака

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 T 1 -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 %).
