Abstract: Magnetic resonance diffusion tensor imaging (DTI) combined with acoustic pulsed radiation force imaging (ARFI) was used to measure the renal cortex of both kidneys in renal insufficiency group and healthy control group, and the diagnostic value of DTI and ARFI combined in renal insufficiency was discussed. The results showed that the shear wave velocity (SWV) of renal parenchyma, renal sinus and the junction of renal parenchyma and renal sinus in renal insufficiency group was higher than that in healthy control group (P<0.05).The SWV values of renal parenchyma, renal sinus and the junction of renal parenchyma and renal sinus in stage Ⅳ were higher than those in stage Ⅲ, Ⅱ andⅠ in RENAL insufficiency group (P<0.05). The combination of DTI and ARFI techniques can quantitatively diagnose the degree of renal dysfunction qualitatively, with a high sensitivity, which can be used as a diagnostic basis for staging renal dysfunction and has high clinical value.
