Preoperative APT signal intensity (SI), mean diffusivity (MD), mean kurtosis (MK) of HCC were measured and compared. Those quantitative magnetic resonance imaging (qMRI) parameters were compared using an analysis of variance. The correlations between the qMRI parameters and the histological grades were determined using Spearman’s rank analysis. In addition, the predictive performance for differentiating low- (G1 and G2) from high-grade (G3 and G4) HCC was evaluated using receiver operating characteristic (ROC) curve analysis.Results: Significant differences were found in APT SIs, MD, and MK among the four groups (P< 0.05). Moderate to good relationships were found between the histologic grade of HCC and APT SI and MK (r=0.679, P< 0.001 and r=0.539, P< 0.001, respectively). The area under the ROC curves (AUCs) of APT SI, MK, and MD for differentiating low- from high-grade HCC were 0.890 (95%CI: 0.805– 0.947), 0.765 (95%CI: 0.662– 0.849) and 0.717 (95%CI: 0.611– 0.808), respectively. Comparison of ROC curves showed a significantly higher AUC of APT SI compared with those of the DKI-derived parameters (P < 0.05).Conclusion: The APT imaging may be more accurate than DKI for predicting the histological grade of HCC.Keywords: hepatocellular carcinoma, amide proton transfer, diffusion kurtosis imaging, histological gradehttps://www.dovepress.com/amide-proton-transfer-imaging-vs-diffusion-kurtosis-imaging-for-predic-peer-reviewed-article-JHChepatocellular carcinomaamide proton transferdiffusion kurtosis imaginghistological grade |
