MSCT低剂量扫描在育龄期男女盆腔检查的临床应用价值研究

Clinical Application of Low-dose MSCT in Pelvic Examination of Men and Women in Childbearing Age

目的:探究MSCT低剂量扫描在育龄期男女盆腔检查的临床应用价值。方法:选取2016年3月到2017年10月期间来我院行盆腔检查的50例体检者作为研究对象,采用数字随机分组方法进行分组,均进行低剂量扫描,A组25例进行50m As剂量扫描,B组25例进行25m As剂量扫描,对比两组诊断符合率、图像质量等指标。结果:A组诊断符合率为92.00%(23/25),B组为76.00%(19/25),(P<0.05);A组图像质量明显优于B组(P<0.05)。两组CTDIvol、DLP对比存在显著差异(P<0.05)。其中,A组CTDIvol为(8.28±0.54)Gy,B组为(2.06±0.28)Gy,(P<0.05)。结论:MSCT 50m As低剂量扫描可获得较高的诊断符合率,而且图像质量比较接近原图,辐射量少,具有较高的应用价值。

Objective： To explore the clinical value of low-dose MSCT in pelvic examination of men and women in childbearing age. Methods： Fifty patients were enrolled in this study from March 2000 to October 2017. The patients were divided into two groups according to the method of digital randomization. The patients in group A were treated with 50 m As dose group,25 cases of group B were 25 m As dose scan,compared with the two groups of diagnostic accuracy,image quality and other indicators. Results： The coincidence rate of group A was 92. 00%（ 23/25） and 76. 00%（ 19/25） in group B（ P 0. 05）. The quality of group A was better than that of group B（ P 0. 05）. There were significant differences in CTDIvol and DLP between the two groups（ P 0. 05）. Among them,CTDIvol was（ 8. 28 ± 0. 54） Gy in group A and（ 2. 06± 0. 28） Gy in group B（ P 0. 05）. Conclusion： MSCT 50 m As low dose scanning can obtain a higher diagnostic coincidence rate,and the image quality is close to the original image,the radiation is small,has a high application value.
