Review principles of tissue signal as it relates to the
measured transverse magnetization (Mxy) in both spin echo and gradient
echo imaging. Review imaging parameters used to
achieve a "steady state" condition.
Discuss Time-of-Flight (TOF) imaging techniques.
Consider methods of flow saturation in black blood
imaging methods.
Review the principles of Phase Contrast (PC) imaging.
Discuss the function of bipolar gradients and the
resultant effects on the transverse magnetization and phase shift of
moving spins.
Consider the relationship of flow velocity and phase
shift when determining Maximum Encoding Velocity (VENC) values.
Discuss various PC imaging techniques.
Compare TOF and PC techniques with respect to signal
characteristics, spatial resolution, and acquisition time.
Discuss the advantages and disadvantages of various
techniques.
Review methods of image presentation.
Compare MRA techniques to contrast angiography. |
