Imaging Studies IV: Magnetic Resonance Imaging

12
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

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...

研究的目的:

  • 评估使用超高性能梯度在前列腺成像3TMRI的可行性和好处.
  • 为了证明高梯度振幅和死亡率对改善前列腺MRI的价值.

主要方法:

  • 前列腺MRI对4名健康男性进行,使用原型3TMRI系统,其梯度幅度为200mT/m,滑动速率为500T/m/s.
  • 扩散加权成像 (DWI) 在标准和最大梯度性能设置下进行.
  • 图像质量指标,包括回声间隔和回声时间 (TE),与标准的临床系统进行了比较.

主要成果:

  • 在高性能DWI期间,在任何受试者身上都没有报告外围神经刺激.
  • 在前列腺的后端外围区域观察到图像扭曲的减少.
  • 在高梯度DWI期间,前列腺和周围肌肉中观察到更高的信号强度.

结论:

  • 同时的高梯度振幅 (200mT/m) 和死亡率 (500T/m/s) 是可行的体内人类前列腺MRI.
  • 增强的梯度性能有效地减轻了前列腺成像中的T2衰变引起的图像扭曲和信号噪声比 (SNR) 问题.
