Diffusion-Weighted MR Imaging of Kidney / 实用放射学杂志

ABSTRACT

Objective To explore the characteristics and applied value of diffusion-weighted MR imaging of kidney in healthy people.Methods Using Philips Gyroscan Intera 1.5T MR System,DWI of kidney was performed in 40 healthy adult volunteers,the ADCs of renal cortex and medulla were measured.Results The cortex and medulla of the normal kidney could be clearly showed by DWI.The ADCs of the cortex medulla and average were 3.08?0.52,2.74?0.68 and 2.91?0.58;2.79?0.51,2.53?0.65 and 2.63?0.62;2.64?0.43,2.32?0.47 and 2.48?0.44 when the b values were 300,500 and 800 s/mm2,respectively.The ADC was higher in the cortex than that in the medulla.Conclusion DWI can be used in kidney,it may be helpful for the diagnosis of renal diseases.
