虚拟仿真(Virtual Reality,简称VR)技术近些年在各个领域取得杰出成果,并广泛应用于医学教育领域。为了顺应新时代发展的需求,培养新模式新理念的医学生,深化医学教学研究势在必行。VR应用于医学影像教学,不仅可以提高学生学习的积极性及灵活性,极大地激发学生对医学影像学的兴趣,并且提供了一个综合运用多学科知识的平台。Virtual Reality (VR) technology has made outstanding achievements in various fields in recent years and has been widely used in the field of medical education. In order to meet the needs of the development of the new era, it is imperative to deepen medical teaching and research to cultivate medical students with new models and new ideas. The application of VR in medical image teaching can not only improve students’ learning enthusiasm and flexibility, greatly stimulate students’ interest in medical imaging, but also provide a platform for comprehensive use of multidisciplinary knowledge.
目的探讨表观扩散系数(apparent diffusion coefficient,ADC)值与乳腺癌病理分级是否具有相关性。材料与方法回顾性分析经病理证实并具有病理分级的66例乳腺浸润性导管癌,对病灶进行ADC值测量,取感兴趣区的ADC均值ADCmean及最小值ADCmin。依据治疗及预后(病理分级、淋巴结情况)分为病理分级、预后复发两组,采用SPSS19.0(One-way ANOVA、LSD检验、Spearman等级秩相关)进行统计学分析。结果 ADCmean值在病理分级1、2、3组内均数分别为0.993×10-3 mm2/s、0.969×10-3 mm2/s、0.926×10-3 mm2/s,ADCmin值的均数分别为0.849×10-3 mm2/s、0.660×10-3 mm2/s、0.535×10-3 mm2/s。ADCmean值在预后复发A、B、C组内均数分别为1.014×10-3 mm2/s、1.029×10-3 mm2/s、0.919×10-3 mm2/s,ADCmin值的均数分别为0.918×10-3 mm2/s、0.750×10-3 mm2/s、0.540×10-3 mm2/s。A D C m e a n与病理分级、预后复发分组间不具有相关性,A D C m i n与病理分级组(r=-0.615,P=0.000)、预后复发组(r=-0.754,P=0.000)间呈负相关。结论ADCmin值可以作为对乳腺癌术前治疗方案的制定及预后复发进行初步评估的一种指标。
