MRI Angio Principles Quiz

• It manipulates the phase of the magnetization to derive contrast between flowing blood and stationary tissues
• It uses contrast media to visualize blood
• It repeats the RF pulses to the longitudinal spins, causing loss of signal in the longitudinal spins
• It is based on flow-related enhancement with high signal for inflow and low signal for outflow (correct)

• To derive contrast between flowing blood and stationary tissues
• To visualize blood using contrast media
• To repeat the RF pulses to the longitudinal spins
• To reduce unwanted signal from blood flowing into the imaging field from a certain direction (correct)

• It repeats the RF pulses to the longitudinal spins, causing loss of signal in the longitudinal spins
• It uses contrast media to visualize blood
• It can quantify velocity and direction of blood flow (correct)
• It is based on flow-related enhancement with high signal for inflow and low signal for outflow
