Quiz: MR Spectroscopy 2

Objectives: This course outlines the steps and considerations that must be taken in order to obtain spectra of an acceptable standard for clinical and research purposes.

1. How is MRS a quantitative technique? Because the concentration of a metabolite is proportional to :*

The number of spins
M₀
The signal induced in the coil
All of the above

2. How can field homogeneity be improved?*

Make the acquisition voxel bigger
Improve shimming
Use a higher field magnet
Use a more sensitive RF coil

3. How can signal to noise ratio be improved?*

Make the acquisition voxel bigger
Improve shimming
Use a shorter echo time
All of the above

4. What is an acceptable standard for water suppression?*

When you have used a suppression technique with adiabatic pulses
When the intensity of the water peak is below the height of the largest metabolite resonance
When you can see the signals from metabolites
When there are no spurious signals
