MRA PT 2

  1. how is contrast in mra maximized
    by enhancing the signal from flowing spins and suppressing signal from stationary spins
  2. what are two ways to suppress stationary spins
    • Perform 2 acquisitions and subtract them
    • Short TR to saturate stationary spins
  3. what is DSA or digital subtraction MRA
    when contrast is selectively produced for moving spins during 2acquisitons
  4. where can we place saturation pulses that will selectively suppress venous flow: leveing only arterial flow
