摘要: 应用磁共振弥散张量成像技术(DTI)联合声脉冲辐射力成像(ARFI)测量肾功能不全组及健康对照组双肾肾皮质,探讨DTI、ARFI联合应用对肾功能不全的诊断价值。结果发现,肾功能不全组患者肾实质、肾窦、肾实质与肾窦交界处的剪切波速度(SWV)均高于健康对照组(P<0.05);肾功能不全组Ⅳ期肾实质、肾窦、肾实质与肾窦交界处SWV值均高于Ⅲ、Ⅱ、Ⅰ期,存在差异性(P<0.05)。DTI、ARFI技术联用可以定性定量诊断肾功能不全程度,敏感度较高,可作为肾功能不全分期诊断依据,临床价值较高。

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.
