Magnetic Resonance Imaging

4.8K
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...

Imaging Studies I: CT and MRI

95
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

科学领域:

  • 磁共振成像是一种磁共振成像技术.
  • 放射学 放射学是一门学科.
  • 生物医学工程 生物医学工程

背景情况:

  • 在7特斯拉 (7T) 的高分辨率3D同位素轮旋转回声 (TSE) 腕部MRI对于解剖细节有价值.
  • 在不影响图像质量的情况下实现更快的采集时间仍然是一个挑战.

研究的目的:

  • 为了评估压缩感应 (CS) 加速7T手腕MRI用于高分辨率的3D同位素TSE获取.
  • 为了将CS加速扫描与SENSE加速扫描进行比较,无论是否有脂肪抑制 (FS/NFS).

主要方法:

  • 采用SENSE和CS加速 (7分钟与4分钟相比) 获得0.45毫米的同位素TSE手腕MRI扫描.
  • 获得0.35毫米同位素CS TSE手腕MRI扫描 (7分钟) 进行比较.
  • 优化非脂肪抑制 (NFS) 协议,以减轻化学转移人工物.
  • 通过定性分析和放射科医生分级来评估图像质量和解剖学可见性.

主要成果:

  • 压缩传感 (CS45) 实现了4分钟的采集时间,但与SENSE加速扫描 (SENSE45) 相比,其图像质量较差.
  • 更高分辨率的CS (CS35) 在7T手腕MRI中没有显示出与SENSE45相比的明显优势.
  • 非脂肪抑制的CS35显示出增强骨敏度的潜力,尽管在统计学上没有显著的群体水平的改善.

结论:

  • 压缩感应 (CS) 能够缩短7T手腕MRI的扫描时间,在维护的voxel大小下,但在图像质量上有所妥协.
  • 在这个阶段,当扫描时间保持时,CS并没有为3D 7T TSE手腕MRI提供明确的优势.
  • 对于7T手腕MRI应用,建议进一步优化CS获取和重建技术.
