【摘要】：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。
[Abstract]:Objective to investigate the effect of food intake and ROI on real-time tissue elastography (RTE) of liver. Methods 112 healthy volunteers were divided into two groups: study group (72 cases) and control group (40 cases). RTE was performed with two different areas of ROI (larger ROI:28 mm 脳 26 mm, smaller ROI:13 mm 脳 10 mm). The hepatic fibrosis index (LF index),) was measured before and after feeding in the study group. The fasting LF index, was measured twice in the control group at intervals of 30 ~ 40 min and analyzed statistically. Results there was no significant difference in age, sex and BMI between the two groups (P < 0. 23 or 0. 57 or 0. 24). The postprandial LF index in the study group was higher than that in the preprandial group (P < 0. 05), but there was no significant difference between the control group and the control group before and after the two examinations (P 0. 05). In the study group, the LF index measured before and after meal, after meal and before and after the control group was 0.001 higher than that in the control group when larger ROI was selected. Conclusion eating can affect the results of RTE, compared with fasting, postprandial LF index is higher, and different area of ROI can also affect the results of RTE. The LF index is higher when the larger ROI is selected.
