- 人工智能在医学中的应用
背景情况:
- 脊柱成像的标准护理 (SOC) 核磁共振可以耗时.
- 深度学习 (DL) 算法为加速图像采集和改善图像质量提供了潜力.
研究的目的:
- 将DL重建的MRI与SOCMRI的性能进行比较.
- 在图像采集时间,图像质量和脊柱异常的诊断互换性方面评估DL MRI.
主要方法:
- 对200名脊柱不适的参与者进行前性研究,他们接受了SOC和DL加速MRI.
- 信号与噪声比率 (SNR) 和对比与噪声比率 (CNR) 的定量分析.
- 放射科医生对主观图像质量和病变检测的评估,并对可互换性和一致性进行统计分析.
主要成果:
- DL MRI 将扫描时间减少了约40%,SNR和CNR显著增加 (P < 0.001).
- 在检测脊柱异常 (等效指数<4%) 方面,DL MRI与SOC MRI的互换性得到证明.
- 在DL和SOCMRI之间,主观图像质量或病变检测率没有显著差异.
结论:
- 用DL重建的MRI提供了高质量的诊断图像,同时减少了患者检查时间.

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...
