目的评价光谱CT显示肾模型中囊性高衰减病变特征的能力,并且验证光谱CT有助于鉴别肾囊性病变与蛋白质含量高及出血或发生恶变并有强化的病变的假说。材料与方法 Objective To evaluate the ability of spectral CT to characterize cystic lesions with high attenuation in renal models and to verify the hypothesis that spectral CT may be useful in differentiating renal cystic lesions from high protein content, with hemorrhages or malignant lesions, and with enhanced lesions.
