Area of Science:

  • Physics
  • Medical Imaging

Context:

  • Magnetic Resonance Imaging (MRI) relies on tissue properties like T1 and T2 relaxation times and proton density.
  • Proton motion significantly impacts MRI image quality, causing artifacts.

Purpose:

  • To review the physical principles of MR angiography.
  • To demonstrate clinical applications of MR angiography.

Summary:

  • MR angiography leverages proton motion, specifically time-of-flight (TOF) and phase effects, for flow visualization.
  • Two main techniques, TOF and phase contrast MR angiography, utilize distinct flow effects while suppressing others.
  • These methods are crucial for compensating for flow-related artifacts in MRI.

Impact:

  • Enhances understanding of MR angiography techniques.
