Cards In This Set
| Front | Back |
 |
Susceptibility Artifact (use spin echo or increase turbo factor)
|
 |
Flow Artifact(CSF in brain. Want phase encoding to where it reduced motion)
|
 |
Motion Artifact(even slight movement can show up as artifact)
|
 |
Zipper artifactRF leakage (open door)
|
 |
Aliasing Artifact(Make FOV big enough or add phase oversampling)
|
 |
Chemical Shift(fat/H20 phase slightly different, & some cancel out) Decrease FOV or increase bandwidth
|
 |
Black Boundary (In/out of phase fat/water)
|
 |
Gibbs Effect(Seen on phantoms; low resolution)
|
 |
Zero Filling Artifact (Only Partially fills, inputs 0's for the rest of the K-space)
|
 |
Moire Fringe Artifacts(On localizer; lack of homogeneity)
|
 |
 Random Motion Artifact(Two lines in k-space disturbed; looks worse b/c goes through center [point of highest intensity]) |
 |
 Periodic Motion Artifact(4 lines of k-space disturbed; not as bad b/c doesn't go through center) |
 |
 Random Noise |
 |
 Large RF spike near k-space center(One point in k-space disturbed) |
 |
 Large RF Spike near k-space periphery |
