Abstract

Objectives: To explore whether T1 mapping parameters and the functional liver imaging score (FLIS) based on Gd-EOB-DTPA MRI could evaluate liver regeneration after hepatectomy for HCC patient.

Methods: This retrospective study finally included 60 HCC patients (48 men and 12 women, with a median age of 53 years). T1 relaxation time of liver before gadoxetic acid injection (T1_pre) and during the hepatobiliary phase (T1_HBP), reduction rate (Δ%) and FLIS were calculated, their correlations with liver fibrosis stage, hepatic steatosis, and liver regeneration, quantified as regeneration index (RI), were assessed by Kendall's tau-b correlation test or Spearman's correlation test. Multivariate linear regression analyses were used to explore the indicator of RI.

Results: T1_pre, T1_HBP, Δ%, and FLIS manifested significant correlation with fibrosis stage (r = 0.434, P =0.001; r = 0.546, P < 0.001; r = -0.356, P =0.005; r = -0.653, P <0.001, respectively). T1_pre showed significant correction with steatosis grade (r = 0.415, P =0.001). Fibrosis stage and steatosis grade were associated with RI (r = -0.436, P<0.001; r = -0.338, P =0.008). Accordingly, T1_pre, T1_HBP and FLIS were the significant predictors (P<0.05) of RI in multivariate analysis. Similarly, in the patients undergoing minor hepatectomy (n=35), T1_HBP, Δ% and FLIS were related to RI (P<0.05) in multivariate analysis. Nevertheless, in the patients undergoing major hepatectomy (n=25), no T1 mapping parameter and FLIS was the independent predictor of RI.

Conclusions: T1 mapping parameters and FLIS were the potential noninvasive indicators of liver regeneration, except for HCC patients undergoing major hepatectomy.

Clinical relevance statement: The value of T1 mapping and FLIS with Gd-EOB-DTPA MRI for accurate preoperative evaluation of liver regeneration is critical to prevent liver failure and improve prognosis of HCC patients.

肝切除后肝癌患者肝再生术前T1作图及gd - eob - dtpa增强磁共振肝功能成像评分评估

目的：探讨基于Gd-EOB-DTPA MRI的T1定位参数和肝脏功能成像评分（FLIS）对HCC患者肝切除术后肝脏再生的评价价值。方法：本回顾性研究最终纳入60例HCC患者（男性48例，女性12例，中位年龄53岁）。计算加多etic酸注射前（T1pre）和肝胆期（T1HBP）肝脏T1松弛时间、还原率（Δ%）和FLIS，并通过Kendall's tau-b相关检验或Spearman相关检验评估其与肝纤维化分期、肝脂肪变性和肝脏再生的相关性，量化为再生指数（RI）。采用多元线性回归分析对RI指标进行探讨。结果：T1pre、T1HBP、Δ%、FLIS与纤维化分期有显著相关性(r = 0.434, P =0.001；r = 0.546, P < 0.001；r = -0.356, P =0.005；r = -0.653, P < 0.001)。T1pre与脂肪变性分级有显著的校正（r = 0.415, P =0.001）。纤维化分期和脂肪变性分级与RI相关（r = -0.436, PP =0.008）。因此，T1pre， T1HBP和FLIS是显著的预测因子（PHBP， Δ%和FLIS与RI相关）。结论：T1定位参数和FLIS是肝再生的潜在无创指标，除了接受大肝切除术的HCC患者。临床相关性声明：Gd-EOB-DTPA MRI T1定位和FLIS对肝再生术前准确评估的价值对于预防肝衰竭和改善HCC患者预后至关重要。
