5 Questions
What does the indication +Gz in Figure 29 mean?
A slightly stronger Bo field in the head compared to the iso-center
Why do protons in the head spin faster than those in the iso-center?
Due to a stronger Bo field in the head
How does the choice of frequency range for RF excitation pulse impact imaging?
It affects which section of the patient will generate an MRI signal
What is another term for selecting specific sections based on Larmor frequencies?
Slice-Selection
Why can MRI slices be acquired at any angle or orientation in a patient?
As gradient magnetic fields can be applied in any orientation
Test your knowledge on how additional magnetic fields in the Z-direction affect MRI readings and Larmor frequency. Understand how variations in Bo field impact proton spinning frequencies.
