To avoid the "magic angle" (an artifactual brightness seen use a longer TE, reposition the knee, orient the affected anatomy to another angle
in the medial segment of the posterior horn of the lateral
meniscus when short TEs are used) artifact when imaging
the knee,
To best visualize the anterior cruciate ligament on knee externally rotate the leg about 15
MR
When using MRA to evaluate intracranial vascularity, flow 3D time of flight MRA or 3D phase contrast MRA
within smaller vessels can best be demonstrated by
To produce the echo, a gradient echo pulse sequence a gradient magnetic field only
uses
The rate of dephasing due to inhomogeneities is called T2 inhomogeneity
If the TR of a gradient echo pulse sequence is steady state
considerably less than the T2 (and T2*), the condition that
will exist is known as
The gradient that is on during the production of the echo frequency
is the __________ encoding gradient
The gradient that is on longest is the __________ encoding frequency
gradient
