248. 全身核磁共振与液体活检的癌症早期检测
from 知为谁 · host 知为谁
这份文本探讨了全身核磁共振(MRI)和液体活检(循环肿瘤DNA检测)这两种早期癌症筛查方法的比较。文章详细解释了衡量筛查准确性的关键指标,即敏感性(真阳性率)和特异性(真阴性率),并指出在癌症筛查中,高敏感性比高特异性更受重视,因为避免漏诊早期癌症更为重要。通过分析现有经批准的癌症筛查手段以及这两种新技术的具体数据,文本发现全身MRI在敏感性方面通常优于液体活检,而液体活检则在特异性上表现更佳。最终,作者建议将这两种方法结合使用,以实现早期癌症检测的最佳平衡。内容来源:https://www.emigal.com/2024/06/27/full-body-mris-vs-liquid-biopsies-for-early-cancer-detection/
