Abstract:
Objective To study the applied value of MR diffusion-weighted imaging(DWI)and apparent diffusion coefficient(ADC)value in chronic kidney disease(CKD).Methods 10 healthy volunteers and 45 patients with different period of CKD underwent routine MRI and DWI.The DWI features were observed.The ADC values were acquired by using Philips soft package on the ADC images.Results Under different b value(300 s/mm2,500 s/mm2 and 800 s/mm2),the ADC value of CKD were 2.29?0.27,2.07?0.21 and 1.91?0.22,respectively,which were significantly lower than that in normal kidneys,and there was statistical difference between different group of CKD.Conclusion DWI may be a noninvasive method to evaluate the renal function.
