MRI MODULE 4 Questions And Answers 100%
Correct
Which of the following are included in T2* contrast? spin-spin interactions & magnetic
field inhomogeneities
The signal immediately induced following the initial 90degree excitation pulse is known as:
free induction decay (collect echo data)
iN SPIN-ECHO PULSE SEQUENCE, THE TIME FROM THE 90DEGREE rf PULSE TO THE
NEXT 90DEGREE rf PULse is called the ___ repetition time (TR)
The term "spin density" reflects the # of protons present in a given volume of tissue
Which RF pulse is used to flip the longitudinal magnetization into the transverse plane
90degrees
A pulse sequence consists of the initial 90degree RF pulse, followed by 5 successive 180degree
RF pulses. This type of scan is known as a___ turbo spin echo
A pulse sequence consists of the initial excitation pulse, 5 successive 180degree RF pulses,
followed by another 90degree RF pulse. How many echoes will be collected? 5
