能谱CT成像在鉴别肾透明细胞癌和肾乳头状癌的应用OA
CT Spectral Imaging in Differential Diagnosis of Renal Clear Cell Carcinoma and Renal Papillary Carcinoma
目的：研究能谱CT在肾癌病理分型方面的作用。方法：将45例肾癌患者进行能谱CT扫描，然后利用GSI后处理软件，测量病灶内感兴趣区的碘-水浓度、水-碘浓度、能谱曲线及40~140 keV下的CT值，分析不同病理类型的肾癌能谱CT的表现。结果：肾透明细胞癌与肾乳头状细胞的碘浓度、能谱曲线斜率40~140 keV下的CT值的平均值差异均有统计学意义（P<0.05），而各组之间水浓度的平均值差异无统计学意义（P>0.05）。结论：肾透明细胞癌…查看全部>>
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…查看全部>>
