Echo
|
The tiny signal that comes out of the patient containing T1 relaxation, T2 relaxation and proton density information
|
|
|
Echo Time (TE)
|
The time from the excitation pulse to the measurement of the echo
|
|
|
Electromagnetism
|
Connection between electricity and magnetism which causes a magnetic field to be created whenever a charged particle moves
|
|
|
Excitation Pulse
|
RF energy used to tilt the magnetization from the longitudinal direction toward the transverse plane.

|
|
Larmor Equation
|
Describes the influence of the magnetic field strength on the processional frequency of the protons' net magnetization
|
|
|
Longitudinal Direction
|
The direction parallel to the magnetic field of the MR system
|
|
|
Net Magnetization
|
The magnetization that remains after those protons which are lined up against the magnetic field have cancelled an equal number aligned with the field
