超声内镜联合Photoshop对食管间质瘤与 平滑肌瘤鉴别的运用

Endoscopic ultrasonography combined with photoshop software in the identification of esophageal stromal tumors and leiomyoma

摘要:

目的 运用Photoshop软件分析食管间质瘤与平滑肌瘤的超声内镜影像，探讨其鉴别两疾病的价值。 方法 利用Photoshop软件分析经病理及免疫组化确诊的9例食管间质瘤和42例食管平滑肌瘤的超声内镜图像，分别测定间质瘤和平滑肌瘤瘤体感兴趣区的灰度平均值（表示回声强度）与灰度标准差平均值（表示回声均匀度）。 结果 9例食管间质瘤超声内镜图像灰度平均值的均数为73.47，42例食管平滑肌瘤图像灰度平均值均数为58.08，两者差异有显著性（t =4.367，P <0.01）；9例食管间质瘤超声内镜图像灰度标准差的均数为21.12，42例食管平滑肌瘤图像灰度标准差的均数为13.93，两者差异有显著性（t =2.894，P <0.01）。 结论 在超声内镜下食管间质瘤回声强度总体上高于食管平滑肌瘤，而食管平滑肌瘤的回声均匀性优于食管间质瘤，通过Photoshop软件分析超声内镜图像的灰度平均值及灰度标准差可以有助于鉴别食管间质瘤和食管平滑肌瘤。

Abstract:

【Objective】 To compare the endoscopic ultrasonography (EUS) images of esophageal stromal tumor and leiomyoma with the help of photoshop software , and to study its differential diagnostic value. 【Methods】 To collect the EUS images of nine esophageal stromal tumor and forty two esophageal leiomyoma which were confirmed by pathological and immunohistochemical examination and make a image analysis of the regions of interest (ROI) by photoshop software. The mean gray value of the image represents the intensity of echo and the gray value standard deviation of the image represent the uniformity of echo. 【Results】 There was significantly different from esophageal stromal; tumor to esophageal leiomyoma in mean gray value of EUS image (P <0.01). The mean gray value of EUS image of the 9 esophageal stromal tumor was 73.47, the esophageal leiomyoma was 58.08; There was also significantly different from esophageal stromal tumor to esophageal leiomyoma in the mean gray value standard deviation of EUS image (P <0.01), The mean gray value standard deviation of EUS image of esophageal stromal tumor was 21.12, the esophageal leiomyoma was 13.93. 【Conclusion】 The echo intensity of esophageal stromal tumor was generally higher than that of esophageal leiomyoma, and the echo uniformity of the esophageal leiomyomawas better than that of esophageal stromal tumor, photoshop software contributes to the identification of esophageal stromal tumors and esophageal leiomyoma.
