1.6 - Fat
Suppression |
| Fat
suppression is extremely important for orthopedic applications
to aid in visualizing abnormal signal intensities. Suppression
of signal from fat improves the conspicuity of fluids such as
marrow edema, fluid in tendon defects, and joint effusions.
Areas of accumulated contrast agent are more easily detected
without the high signal presence of fat, allowing improved
sensitivity to areas of abnormal contrast enhancement. A
fat-suppressed image of a bone contusion is shown in Figure
1.27 as an example. Several techniques are available to
suppress the signal from fat, each having its own associated
strengths and weaknesses. |
