摘要
Abstract
Objective To evaluate the differences in contouring of gross tumor volumes (GTV) between different physicians and analyze causes. Methods CT images from patients with nasopharyngeal neoplasms and lung neoplasms were reviewed by 3 radio - therapists and 3 radio diagnosticians with more than 10 years experience. The variability of GTV volume, the maximum value of X axle of layer and coronal section were calculated. The differences of GTV between the two departments were analyzed. Results The volume of GTV by radio - diagnosticians were small er than that by radiotherapists. The radio - diagnosticians were found more accurate in GTV delin eation than radiotherapists, but the variability in GTV delineation of layers and coronal sections of lung neoplasms was not statistically significant. Conclusion More attention should be paid to the variability of GTV delineation by physicians from different departments to improve the level of im age-diagnose in radio-therapists. Advanced image examination approaches and cooperation of ra diation oncologists should be introduced to enhance the accuracy of target region delineation.关键词
