Abstract:
Objective To investigate the magnetic resonance multimodal function imaging characteristics of small hepa-tocellular carcinoma and evaluate its diagnostic value in small liver cancer. Methods Thirty-nine patients with small hepato-cellular carcinoma were selected in the First Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2018. The magnetic resonance plain scan data,dynamic enhance data and diffusion imaging data of all patients were analyzed. Results Forty-five lesions were found by plain scan,and 48 lesions(37 lesions were rapid rise and rapid descent type,6 le-sions were flatbed type,3 lesions were slow ascent and rapid descent type,2 lesions were not obvious strengthening type)were found by dynamic enhancement. The lesions were hyperintense or slightly hyperintense on the diffusion weighted imaging (DWI)image. The lesions were hyperintense or slightly hyperintense on the DWI. The main shape of lesions was round,irregu-lar ring and nodositas. The apparent diffusion coefficient(ADC)value of cancer tissue and normal liver tissue gradually de-creased with the increase of b value. Under the same b value,the ADC values of small hepatocellular carcinoma was significant-ly lower than that in the normal liver tissue(P < 0. 05). Conclusion Magnetic resonance multimodality functional imaging (magnetic resonance imaging dynamic enhanced combine with multi-b value DWI)can effectively improve the diagnostic effi-cacy of small hepatocellular carcinoma.
