伽玛照相机甲状腺显像定位器的应用

Application of Thyoid Nuclide Imaging Locator to Y-camera

目的 :评价核素显像定位器在核素显像中的应用价值。方法 :对使用显像定位器前的 2 86例甲状腺显像照片以及使用显像定位器后的 2 5 0例甲状腺显像照片进行回顾性比较分析。结果 :甲级片数量明显增加 ,经统计学处理 (卡方检验 ) ,P<0 .0 0 5 ,两组间比较具有显著性差异。结论 :安装甲状腺定位器后甲级片数量增加 ,乙、丙级片数量减少 ,影像质量较安装前明显提高 ,进而提高了甲状腺疾病诊断率 。

In order to appraise practical value of nuclide developing locator, 286 thyroid imaging pictures (group I) taken before using the locator were retrospectively compared with 250 thyroid imaging pictures (group Ⅱ) taken after using the locator. As a result, the number of Grade A pictures was found to have increased greatly. The difference between group I and Ⅱ is significant (P<0.005), according to a Chi-squared test. With the thyroid nuclide developing locator, the increased number of Grade A pictures and the reduced number of Grade B/C pictures indicated remarkably higher quality of imaging than before, thus improving the diagnostic accuracy for diseases of thyroid gland.
