Abstract: Objective The aim of this study was to investigate the differential diagnosis of hepatic hemangioma (HH) and hepatocellular carcinoma (HCC) by multi-b-value diffusion-weighted imaging (DWI) of high-field magnetic resonance (MR). Methods 85 patients with focal space-occupying liver lesions (FLL) were encountered in our hospital between June 2019 and May 2021, and all underwent high-field magnetic resonance and the apparent diffusion coefficient (ADC) was recorded. All patients received hepatectomy, and the histopathological examination was performed. The receiver operating characteristic (ROC) curve was drawn and the area under the curve (AUC) was calculated to testify the differential diagnosis performance of ADC value for HH and HCC. Results The results of pathological examination post-operationally showed that among the 85 patients with FLL, the HH was found in 28 cases (32.9%), the focal liver nodular hyperplasia (FNH) was found in 18 cases (21.2%) and the HCC was found in 39 cases (45.9%); the ADC of cancerous foci at b=50 s/mm2, b=400 s/mm2 and b=1000 s/mm2 were (2.41±0.20)×10-3/mm2/s, (2.02±0.19)×10-3/mm2/s and (1.73±0.15)×10-3/mm2/s, the ADC of FNH foci were (2.43±0.31)×10-3/mm2/s, (2.05±0.21)×10-3/mm2/s and (2.01±0.18)×10-3/mm2/s, all significantly lower than [(2.63±0.35)×10-3/mm2/s, (2.46±0.32)×10-3/mm2/s and (2.25±0.23)×10-3/mm2/s, respectively, P<0.05] in HH foci; the ROC was drawn based on ADC at b=1000 s/mm2, and the ADC=1.73×10-3/mm2/s was set as the optimal cut-off-value for differential diagnostic of HH and HCC, the performance is excellent with the AUC(95%CI) of 0.727(0.581-0.844, P<0.05), the sensitivity of 80.0% and the specificity of 75.9%. Conclusion The high-field magnetic resonance imaging has a great importance in the differential diagnosis of hepatic hemangioma and hepatocellular carcinoma, and we recommend the ADCs at b equal to 1000s/mm2, which needs further clinical investigation.
