MRI K Space
The number of rows of K Space filled per TR period in a Spin Echo sequence is
1
In K Space, the data containing signal and contrast information are located
Along the central lines
In K Space, the data containing high resolution are located
Along the outer lines
Echoes with the lowest phase encoding gradient (highest signal) are places where in K Space?
Center
The high amplitude signals are stored where in K Space?
Center (where contrast information is also found)
Acquiring a bit more than half the phase dimension k space samples, then interpolating the data with zeroes for the remaining half is a technique known as
Half Fourier, or Zero Fill.
Center of K Space=
Maximum Signal
When only half the views of K Space are filled in the frequency axis, this is known as
Partial of Fractional Echo (an acceleration technique used to shorten TR and TE)
Reducing the number of lines filled in K Space will
Produce an image with decrease in spatial resolution
The number of rows of K Space filled per TR period in a Fast Spin Echo Sequence is
The same as ETL (or TSE factor)
K Space is defined as
The storage location of the MR signal data
Collecting the low frequency (high amplitude signal) data points in K Space at the start of the scan (in a spiral fashion) is known as
elliptic centric k-space filling
