Abstract:Objective To evaluate the diagnostic value of contrast-enhanced ultrasound and magnetic resonance imaging (MR) and
diffusion-weighted imaging (DWI) in the diagnosis of recurrent microcarcinoma of the liver. Methods A total of 26 cases of small
liver cancer with recurrence less than or greater than 1.0 cm who visited our hospital from January 2016 to March 2018 were selected
as the research objects, and their contrast-enhanced ultrasound and mri scanning and DWI image characteristics were analyzed.
Results The results of ceus and mri enhanced scan showed that there were 14 and 11 fast in and out, 6 and 4 fast in and out, 5 and 7
fast in and out, and 1 and 4 in and out, respectively. All of the 26 foci of DWI were high signal. There was no significant difference
in the accuracy of P>0.05 and MR in the diagnosis of recurrent small hepatocellular carcinoma. There was no significant difference
between the two methods. Conclusion The contrast-enhanced ultrasound and MR can sensitively display the internal hemodynamic
characteristics of small hepatocellular carcinoma, and can be used as an imaging method for the diagnosis of recurrent small
hepatocellular carcinoma. DWI combined with enhanced MR can significantly improve the diagnostic accuracy of MR.
