医学图像融合技术在肿瘤放射治疗中的应用

Application of medical image fusion technology in tumor radiotherapy

目的分析医学图像融合技术在肿瘤放射治疗中的应用效果。方法选取2018年1月至2019年12月于本院接受放射治疗的肿瘤患者70例,分别采用CT图像融合技术及MRI图像融合技术,分析患者放射治疗的靶区勾画效果。结果CT联合MRI融合勾画的肿瘤体积高于CT、MRI勾画的肿瘤体积,CT联合MRI融合勾画的肿瘤靶区占MRI勾画的肿瘤靶区比重,低于占CT勾画的肿瘤靶区比重,差异有统计学意义(P<0.05)。与CT联合MRI融合勾画的肿瘤靶区比较,CT显示的勾画靶区差异21例,占30.0%;MRI显示的勾画靶区差异17例,占24.29%;两者比较差异无统计学意义。结论肿瘤放射治疗时采用医学图像融合技术,能提高放射靶区勾画效果,确保放射治疗的安全性及有效性,值得临床推广应用。

Objective To analyze the application effect of medical image fusion technology in tumor radiotherapy.Methods 70 tumor patients who received radiotherapy in our hospital from January 2018 to December 2019 were selected,and CT image fusion technology and MRI image fusion technology were used respectively,and the target area drawing effect of radiotherapy was analyzed.Results The tumor volume of CT combined with MRI was higher than that of CT and MRI,and the tumor target area delineated by CT combined with MRI fusion accounted for the proportion of the tumor target area delineated by MRI,which was lower than the proportion of the tumor target area delineated by CT,and the difference was statistically significant(P<0.05).Compared with the tumor target area delineated by CT combined with MRI fusion,21 cases(30.0%)showed the difference in the target area delineated by CT,17 cases(24.29%)showed the difference in the target area delineated by MRI,and there was no statistical significance between the two methods.Conclusion The application of medical image fusion technology in tumor radiotherapy can improve the effect of radiation target delineation,and ensure the safety and effectiveness of radiotherapy.It is worthy of clinical application.
