科学领域:

放射学放射学是指放射学
医疗成像医学成像
脊柱外科手术脊柱外科手术

背景情况:

计算机断层扫描 (CT) 是骨形态评估的标准,而磁共振成像 (MRI) 在软组织评估方面表现出色.
来自CT的高辐射暴露需要用于骨评估的替代成像技术.
新兴的MRI技术,如合成CT (sCT) 和T1加权异型MRI,旨在提供详细的骨图像,减少辐射.

研究的目的:

评估基于MRI的合成CT (sCT) 对于可视化脊椎解剖与手术规划相关的疗效.
在手术前计划中,将sCT的诊断信心和附加值与3D T1加权的同otropic MRI进行比较.
评估sCT在减少CT扫描相关的电离辐射暴露方面的潜力.

主要方法:

一项前性研究涉及24名成人患者,他们接受了腰椎或十字脊柱稳定手术.
每位患者获得了两个扫描:用于sCT重建的3D双回声T1加权梯度图像和3D同位素T1加权MRI序列.
三名观察员使用利克尔特尺度来评估sCT图像质量,脊椎解剖的可视化,以及与同位素核磁共振相比,对手术前规划的信心.

主要成果:

观察员证实,在94%的病例中,通过sCT充分可视化了相关的脊椎解剖学.

Magnetic Resonance Imaging

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...
