概括

超快速动态增强对比度 (DCE) MRI可以提高乳腺癌检测特异性. 这种方法有可能减少对良性病变的不必要后续检查,提高临床MRI协议的诊断准确性.

科学领域:

放射学放射学是一门学科.
在瘤学瘤学.
医疗成像医学成像

背景情况:

乳房MRI提供高灵敏度但癌症检测的中间特异性.
传统的动态对比增强MRI (DCE-MRI) 依赖于运动特征.
超快速DCE-MRI评估早期对比流入,可能改善诊断性能.

研究的目的:

评估放射学家对超快速DCE-MRI的评估是否提高了临床乳腺MRI协议的特异性.
确定超快速DCE-MRI的诊断性能,以区分良性与恶性乳腺病变.

主要方法:

从2019年3月到2020年8月,对95种乳腺病变 (20种恶性,75种良性) 的回顾性分析.
在对比测试后40秒内获得超快的DCE-MRI,比传统的DCE-MRI更早.
三位失明的放射科医生用超快速的DCE-MRI评估了病变增强时间 (TTE);分析了读者间一致性和诊断性能.

主要成果:

对TTE评估的中度至实质性的读者间协议 (κ=0.63).
良性病变的TTE显著大于恶性病变 (P<.05).
超快的DCE-MRI实现了92%的灵敏度和40%的特异性,可能减少31%的良性随访.

结论:

超快速的DCE-MRI可以增强传统的DCE-MRI,以提高诊断准确度,增加最小的扫描时间.
标准化超快速DCE-MRI的评估标准可能进一步提高读者间的协议和评估的稳定性.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
