摘　　要：目的分析和评估MRI扩散加权成像技术辨别乏脂肪肾血管平滑肌脂肪瘤(RAML)与肾癌的作用。方法选取2020年1月—2021年12月河南省人民医院所收治的168例乏脂肪RAML作为研究对象,其中33例患者于院档案库中有完整的病历资料;另外,选取2021年1月—12月所收治的33例有完整病历资料的肾癌患者作为研究对象,分析患者的MRI扩散加权影像特征与信号特点,并研究测量各病灶的表变扩散系数(ADC)。结果脂肪肾血管平滑肌脂肪瘤患者的ADC值为(1.611±0.20)×10^(-3)mm^(2)/s,肾癌患者的ADC值为(1.459±0.274)×10^(-3)mm^(2)/s,肾癌患者的ADC值明显高于乏脂肪肾血管平滑肌脂肪瘤患者,数据差异具有明显的统计学意义(P<0.05)。结论MRI扩散加权成像技术对于鉴别乏脂肪肾血管平滑肌脂肪瘤与肾癌的作用显著,可为临床治疗乏脂肪肾血管平滑肌脂肪瘤与肾癌提供具有较高准确性的影像特征,对于提升治疗效果与患者的生命质量具有重要意义,应与临床进行广泛运用与推广。Objective To analyze and evaluate the role of MRI diffusion-weighted imaging(DWI)in differentiating fatty renal angiomyolipoma from renal carcinoma.Methods A total of 168 cases of adipose-deficient RAML treated in our hospital from January 2020 to December 2021 were selected as the research objects,among which 33 patients had complete case data in our hospital archives.In addition,33 patients with renal cancer who were admitted to our hospital from January to December 2021 with complete case data were selected as the research objects.The diffusion-weighted MRI image characteristics and signal characteristics of the patients were analyzed,and the surface variation diffusion coefficient(ADC)of each lesion was measured.Results The ADC value of patients with fatty renal angiomyolipoma was(1.611±0.20)×10^(-3)mm^(2)/s,and that of patients with renal cancer was(1.459±0.274)×10^(-3)mm^(2)/s.The ADC value of patients with renal cancer was significantly higher than that of patients with fatty renal angiomyolipoma.The difference was statistically significant(P<0.05).Conclusion MRI diffusion weighted imaging for differentiating renal angiomyolipomas spent fat and kidney function significantly,for the clinical treatment of renal angiomyolipomas spent fat and kidney cancer has a high accuracy of image features,to improve treatment effect is of great significance to the patient’s life quality and should be widely used in clinical promotion.
