1. Magnetic Resonance Learning Objectives
Understand Bloch equation. What does each term mean?
How is each term used to create signal and/or contrast?
Longitudinal Relaxation
Transverse Relaxation
Apply this to calculate Mz after various excitations
Predict transverse magnetization as a function of time.

2. Magnetic Resonance Learning Objectives
Signal Equation - Ch.5
Understand how MR signal represents Fourier representation of object.
What role does the MR coil play?
How do gradient encode signal?
How does gradient waveform relate to k-space trajectory?
How does sampling interval, gradient amplitudes, pulse sequence
determine FOV, resolution, and aliasing?

3. Magnetic Resonance Learning Objectives
- 2D Fourier Transform trajectories
- readout, phase encode, slice selection
- projection reconstruction
For given FOV and resolution, sample interval, determine gradient amplitude.

4. MR Learning Objectives
What causes phase errors in MR?
How do phase errors appear in gradient and spin echo exams?
Signal contrast
How is T1 contrast achieved?
How is T2 contrast achieved?
How do inversion recovery sequences create contrast?
How does SNR vary as sequence parameters change?
- FOV,
- imaging matrix
- receiver bandwidth
What options do you have to change the sequence to change imaging
parameters?
-How can you increase resolution? FOV?
- How do you increase slice thickness?
