MRI Module 6-Pulse Sequence Test Questions
And Answers 100% Correct
Increasing the bandwidth of a sequence from 16 kHz to 32 kHz: decreases signal-to-noise
ratio
A dual-echo image contains both a proton-density image and a T2-weighted image in a single
slice. T/F True
In fast spin-echo imaging, the long row of 180* pulses is called a(n) echo train length
Without making compensation adjustments, a fast spin-echo sequence with a higher echo train
length, such as 10, will produce an image with: increased T2 weighting, blurred edges,
reduced scan time
The following diagram is an example of a(n) _____ pulse sequence. gradient-echo
T2* is the type of image contrast created using a ____ sequence. gradient-echo
Which of the following is not true regarding echo planar imaging (EPI)? it uses an echo
train of multiple 180* RF pulses
____ works well for cardiac imaging EPI
