Presentation Transcript

  1. Soft Tissue Trauma

  2. Achilles Rupture • Disruption of the tendon - edema Normal

  3. Achilles Rupture • T2 image • Focal high signal in tendon (white) • Irregular appearance to tendon • Tendon normally low signal (black)

  4. Felt pop(“weekend warrior” athlete)

  5. Knee injury Normal comparison

  6. ACL Tear ACL Normal comparison

  7. ACL Tear #2 ACL ACL Normal comparison

  8. Knee Trauma

  9. Bone ContusionsPatellar dislocation/relocation pattern • Bone edema as result of contusion • See high signal from bleeding/ fluid in bone marrow • Kissing lesions during dislocation of patella

  10. Knee pain Normal

  11. Anterior horn lateral meniscus tear • Anterior horn meniscal tear • High signal with extension to the superior surface Normal

  12. Knee Pain

  13. Radial tear lateral meniscus Normal High signal medial posterior lateral meniscus = tear Normal

  14. Knee pain basketball player Normal

  15. Jumper’s knee (patellar tendinosis/partial tearing) • High signal from edema in the tendon and adjacent tissues Normal

  16. Muscle Tear • Coronal section of the thigh • High signal on Fat suppressed images • Fluid-Hematoma in adductor muscle group • Compare to right thigh

  17. MyositisOssificans • Amorphous bone formation in soft tissues • Likely related to prior trauma

  18. Widened Mediastinum • Deceleration injury • Widened superior mediastinum • Must exclude positional factors (supine patient, AP film) • CT can identify blood • Angiogram to separate aortic injury from other vessel injuries

  19. Aortic Tear • Arch aortogram • Arrow indicates area of aortic tear
