目的探讨不同医师间及医师内部评价乳腺肿瘤超声造影形态学指标的一致性。方法回顾151例乳腺肿瘤患者的超声造影图像,由2名不同年资超声医师分别在有无临床及病理资料的情况下对图像进行评估,结果采用Kappa检验进行评价。结果 2名医师在判断造影肿块内无灌注区、灌注强度、肿块内1/2无灌注区的有无、肿块内无灌注区面积等指标时有中度以上的一致性,Kappa值均分别为0.432、0.460、0.616、0.761;同一医师在知晓病理结果前后均具有高度一致性,Kappa值均为0.600以上。结论不同医师对超声造影形态学指标存在不同认知,诊断乳腺肿瘤造影的标准有待进一步统一。
Objective To investigate the consistency between different physicians and physicians in evaluating the morphological characteristics of breast tumor by ultrasound contrast. Methods We reviewed 151 patients with breast cancer who had undergone CEUS. Two ultrasound physicians with different age were used to assess the images with or without clinical and pathological data. The results were evaluated by Kappa test. Results The two physicians had a moderate degree of consistency in judging whether there were no perfusion area, perfusion intensity, presence / absence of perfusion area in the tumor mass, no perfusion area in the mass, and Kappa values were 0.432,0.460,0.616,0.761; the same physician before and after knowing the pathological results were highly consistent, Kappa values were more than 0.600. Conclusion Different physicians have different cognition on the morphological indexes of ultrasound contrast, and the standard of diagnosing breast tumor radiography needs to be further unified.
