CT图像直方图分析在鉴别肾细胞癌和乏脂质肾血管平滑肌脂肪瘤中的价值探究

Value of CT Image Histogram Analysis in Differential Diagnosis of Renal Cell Carcinoma and Renal Lipid Vascular Smooth Muscle Lipoma

目的:探究CT图像直方图分析在鉴别肾细胞癌和乏脂质肾血管平滑肌脂肪瘤中的临床价值。方法:选择我院2015年10月14日—2018年10月14日收治的68例肾细胞癌患者(设为对照组)和68例乏脂质肾血管平滑肌脂肪瘤患者(设为研究组)作为研究对象,两组患者均行CT增强扫描和CT图像直方图分析,对比两组患者CT图像直方图特征、CT值、各项直方图参数。结果:研究组患者增强后病灶的直方图高峰较陡直,对照组患者增强后病灶的直方图高峰较平缓;研究组患者CT值显著低于对照组;研究组患者直方图平均数、中位数、最小值均显著高于对照组,研究组患者直方图标准差、峰度值均显著低于对照组,两组对比差异具有统计学意义(P<0.05)。结论:肾细胞癌和乏脂质肾血管平滑肌脂肪瘤的CT图像直方图影像特征、CT值及各项直方图参数具有明显差异,因此,应用CT图像直方图分析能有效对两种病变进行鉴别区分。

Objective:To explore the clinical value of CT histogram analysis in differentiating renal cell carcinoma from renal angiomyolipoma.Methods:68 patients with renal cell carcinoma and 68 patients with renal angiomyolipoma from October 14,2015 to October 14,2018 were selected as study group. CT enhanced scanning and histogram analysis of CT images were performed in both groups. The histogram features, CT values and histogram parameters of CT images were compared between the two groups.Results:In the study group, the peak of histogram was steeper after enhancement.The peak of histogram of the patients in the control group was gentle after enhancement, and the CT value of the patients in the study group was significantly lower than that in the control group.The mean, median and minimum values of histogram in the study group were significantly higher than those in the control group. The standard deviation and kurtosis of the histogram in the study group were significantly lower than those in the control group(P<0.05).Conclusion:There are significant differences in CT histogram features,CT values and histogram parameters between renal cell carcinoma and spent lipid renal angiomyolipoma. Therefore,CT histogram analysis can effectively distinguish the two lesions.
