Y2-MMB(044-047)Computer Lab The Knee Joint Flashcards
Thigh MRI
Point too PCL and ACL ligaments
Knee MRI
Knee MRI :
what is the structure indicated with a C-shaped low density signal ?
Knee Menisci
Knee MRI ;
What is that low signal structure ?
Knee meniscus
Knee MENISCI is dark/light on all MRI sequences
Dark on all sequences
Point to the ant. and post. knee MENISCI and describe their appearance on MRI
-How to differentiate between ant. & posterior ?
-Bow tie appearance in sagittal cut
-Dark on all sequences
-Post horn of medial meniscus larger than ant horn
Describe Grade 1 signal of MENISCI Injury
globular hyper Intense signal within meniscus ,
- asymptomatic
Describe Grade 2 signal of MENISCI Injury
linear hyper Intense signal not reaching articular surface.
-May or may not be symptomatic
Describe Grade 3 signal of MENISCI Injury
linear hyper Intense signal reaching articular surface.
knee MRI sagital cut , point to the lesion and diagnose
Grade 1 Meniscial Injury :
- globular hyperintense signal within meniscus.
knee MRI sagital cut , point to the lesion and diagnose
Grade 2 Meniscial Injury :
