Answers
The 2 types of enhancement media described by Lauffer, the mechanism of T1
agents is
to decrease T1 relaxation time, thus emitting high signal
An analogy for the decoding of the MR signal through Fourier Transform
Basilar membrane processing sound
Logically each line of phase encoding data is combined to allow the FT to
determine the position along the y-axis. The number of phase encoding steps
determines
the number of pixels along the y-axis
In a gradient echo pulse sequence, which flip angle will produce a T2 weighted
gradient echo image.
>20 - <45 degree flip angle
In a horizontal magnet, what is the primary Gs (slice select gradient) for an axial
slice
Gz (axial slice)

Answers
A linear relationship between frequency and position is superimposed on Bo by the
Gp (phase encoding gradient). The Hydrogen protons relative precessional
frequencies determine
phase shifts
Combining a metal ion with a ligand reduces their tendency to bind to proteins,
enzymes, or membranes. The degree to which they dissociate is a measure of their
toxicity
In a phase sequence employing 2DFT, the time can be calculated using which
formula
TR x NEX x Matrix
What pulse imaging technique is in all implementations of MRA
gradient echo
What year was the first MRI enhancement agent approved for clinical use
1988
Increasing NEX

Answers
Increase SNR and Resolution
Inversion time, in an IR pulse sequence, is the time interval between the
180 degree and 90 degree pulses
Increasing the matrix
increase resolution
A pulse sequence that replaces the second RF pulse with a gradient magnetic field
to rephase the transverse vector and produce and echo is called
gradient echo
Increase FOV, TE, Slice thickness does
not affect scan time
In spatial localization which factor most affects slice thickness and position
bandwidth and strength of Gs (slice select gradient)
