健康成年人肾脏磁共振弹性成像及其弹性值测量可行性的初步研究
Feasibility of assessing kidney elasticity by magnetic resonance elastography in healthy volunteers
摘要
Abstract
Objective:To evaluate the feasibility of magnetic resonance elastography(MRE)in evaluating kidney elasticity in healthy adults.Methods:This prospective study recruited 22 healthy volunteers with normal liver and kidney function and no associated diseases.All subjects underwent 3.0 T MRI scan.Two radiologists evaluated MRE images,and the elasticity values of bilateral kidneys were measured separately.Bland-Altman analysis was performed on the measured results.The average elasticity of a normal kidney was calculated.The differences in elasticity between the left kidney and right kidney and between male and female were analyzed.Results:The elasticity values measured by two radiologists had a good consistency(P>0.05).The mean elasticity value of parenchyma of bilateral kidneys was(5.37±0.26)kPa,that of the left and right kidney was(5.38±0.27)kPa and(5.35±0.29)kPa,respectively,with no significant difference(t=-0.311,P>0.05).There was no significant difference in the mean elasticity value between males and females(t=-0.871,P>0.05).Conclusion:MRE can be used to measure the elasticity value of bilateral kidneys with satisfactory repeatability and accuracy.关键词
