How to Read Mri of Knee Meniscus
Minnesota knee surgeon, Dr. Robert LaPrade details the specifics on how to read an MRI of a medial meniscus tear. There are different types of meniscus tears and a horizontal cleavage tear occurs within the fibers of the meniscus and splits the meniscus in the acme and lesser pieces.
To begin, nosotros start with a sagittal view on the lateral side. Every bit we start to go more than towards the midline we start to come across the lateral meniscus. There is a dark appearance to it, so there is no evidence of disruption. As we scan further we come across the ACL and PCL, which both expect normal.
Moving more towards the medial side of the articulatio genus there is evidence of signal changes in the medial meniscus. In this case, nosotros see a complete white laissez passer of fluid in the meniscus, which indicates that in that location is a horizontal cleavage tear.
The next view is a coronal scan. As nosotros course more posteriorly we can see the meniscus is in relatively good position, but nosotros are starting to see increment signal in the torso of the meniscus, which is indicative of a tear. All the way to the posterior medial aspect nosotros can see bespeak intensity, which is consistent with the horizontal cleavage tear.
The last view we wait at is an axial image. In some cases it is challenging to see the tear within the meniscus from this view, only it is important to assess.
