能谱CT成像在鉴别肾透明细胞癌和肾乳头状癌的应用
CT Spectral Imaging in Differential Diagnosis of Renal Clear Cell Carcinoma and Renal Papillary Carcinoma
摘要
Abstract
Objective:To evaluate the value of spectral CT imaging in differential diagnosis of renal clear cell carcinoma and renal papillary carcinoma. Method:45 patients who were diagnosed as renal cell carcinoma(RCC)were scanned in gemstone spectral imaging(GSI)mode. The region of interest in the mass of Iodine-water concentration,water-iodine concentration,spectrum energy curve and CT values at 40-140 keV were measured. Used GSI post processing software to analysis the spectral feature of renal clear cell carcinoma and renal papillary carcinoma. Result:There were significant differences in iodine-water concentration,spectrum energy curve and CT values at 40-140 keV existed between renal clear cell carcinoma and renal papillary carcinoma(P<0.05),but there were no significant difference in water-iodine concentration between them(P>0.05).Conclusion:There are significant differences between renal clear cell carcinoma and renal papillary carcinoma in spectrum energy curve and iodine-water concentration. Spectral CT imagine provides a promising method in differential diagnosis of renal clear cell carcinoma and renal papillary carcinoma.关键词
