Can you tell me if you've been told you needed an MRI on your knee would an ultrasound be just as good?

In brief: Imaging

Mri shows more fine detail than ultrasound, but ultrasound can be useful for looking for fluid in the knee or baker's cyst, looking at the ligaments ; tendons outside the joint (e.
g. Mcl, lcl, patellar tendon), can see changes of arthritis ; can look at the very superficial-most part of the meniscus, but MRI much better for looking deep into the joint at the acl, pcl, full meniscus, etc.
