MRI
n 1: the use of nuclear magnetic resonance of protons to produce
proton density images [synonym: {magnetic resonance imaging},
{MRI}]

magnetic resonance imaging \mag*net"ic res"on*ance im"ag*ing\ n.
(Medicine)
a medical diagnostic procedure utilizing the phenomenon of
{nuclear magnetic resonance} to generate images of internal
parts of the body. It depends on the differential absorption
of electromagnetic radiation by different types of living
tissue in a magnetic field. It is complementary to X-ray
imaging in that the softer tissue show more prominently in
magnetic resonance images, rather than bone, as with X-rays.
It is a non-invasive procedure, allowing such images to be
obtained without penetration of the tissue by objects. It is
abbreviated {MRI}. As with {computerized tomography}, the
results are usually presented as images of sequential planar
sections of that part of the body of concern to the
physician.

  • 核磁共振成像（核成像技术）_百度百科
    MRI被广泛运用在运动相关伤害的诊断上，对近骨骼和骨骼周围的软组织，包括韧带与肌肉，可呈现清晰影像，因此在脊椎及关节问题上，是极具敏感的检查。 因MRI没有辐射暴露的危险，因此经常被使用在生殖系统、乳房、骨盆及膀胱病的侦测及诊断上。
  • 磁共振成像 - 维基百科，自由的百科全书
    MRI是一台巨大的圓筒狀機器，能在受檢者的周圍製造一個強烈磁場區的環境，藉由無線電波的脈衝撞擊身體細胞中的氫原子核，改變身體內氫原子的排列，當氫原子再次進入適當的位置排列時，會發出無線電訊號，此訊號藉由電腦的接收並加以分析及轉換處理
