| 目的 探讨进食及不同面积的ROI对肝脏实时组织弹性成像(RTE)的影响。方法 将112名健康志愿者分为研究组(72名)和对照组(40名),分别以两种不同面积的ROI(较大ROI:28 mm×26 mm,较小ROI:13 mm×10 mm)行RTE检查,测量研究组进食前后肝纤维化指数(LF index),测量对照组间隔30~40 min两次空腹LF index,并进行统计学分析。结果 两组间年龄、性别及BMI差异均无统计学意义(P=0.23、0.57、0.24)。选用较小及较大ROI时,研究组餐后LF index均高于餐前,差异均有统计学意义(P均< 0.05),对照组前后两次检查所测LF index差异均无统计学意义(P均> 0.05)。研究组餐前、餐后及对照组前后两次检查,选用较大ROI时所测LF index均高于选用较小ROI(P均< 0.001)。结论 进食可影响RTE的结果,与空腹相比,餐后LF index增高;不同面积的ROI也可对RTE结果产生影响,选用较大的ROI时LF index更高。 |

| Objective To evaluate the influence of food intake and different ROI on the measurements of liver stiffness with real-time tissue elastography (RTE). Methods A total of 112 healthy volunteers were divided into two groups, including 72 subjects in study group and 40 subjects in control group. RTE measurements were performed on each of the subject with a ROI of 28 mm×26 mm and with another ROI of 13 mm×10 mm. In study group, the liver fibrosis index (LF index)was measured before and after food intake respectively. In control group, RTE measurements were performed on all subjects twice during 30—40 min without food intake. Moreover, the statistical analysis was done. Results There was no statistical difference of the age, sex composition and body mass index between the two groups (P=0.23, 0.57, 0.24). When using both of the two sizes of ROI for RTE, LF index increased after food intake in study group(both P< 0.05), while no statistical difference of LF index was found between twice measurements in control group (both P> 0.05). LF index obtained before and after food intake in study group as well as twice measurement results in control group using lager ROI for RTE were higher than those using smaller ROI for RTE (all P< 0.001). Conclusion Food intake can influence the results of RTE. LF index increases after food intake. Different area of ROI can also influence the measurements of RTE. LF index is higher when selecting lager ROI. |
