It is seen in about 5% of biceps injuries. The ACL is a band of dense connective tissue which courses from the femur to the tibia.It is considered as a key structure in the knee joint, as it resists anterior tibial translation and rotational loads. It can also differentiate a proximal hamstring avulsion tear from a more distal hamstring tear at the proximal muscle-tendon junction or even more distally within the muscle belly. It is seen in about 5% of biceps injuries. UNK the , . Unlike CT scans, MRI works without radiation. Enter the email address you signed up with and we'll email you a reset link.

In contrast, the inner two thirds of the meniscus, known as the “white zone,” does not have a good blood supply. A synovial plica is a shelf-like membrane between the synovium of the patella and the tibiofemoral joint.

Luckily, different types of tissue show up as different shades on an MRI, so it's easy to see contrast where differing tissues meet. A distal biceps tendon tear is an uncommon injury. May show dilated veins. A stronger MRI scan machine with a 1.5 or 3.0 Tesla magnet strength can help to differentiate lower grade hamstring tendonitis from a partial tear or complete tear. Usually it is the long head of the biceps that is completely torn. Number: 0171. The MRI tool uses magnetic fields and a sophisticated computer to take high-resolution pictures of your bones and soft tissues. In contrast, the inner two thirds of the meniscus, known as the “white zone,” does not have a good blood supply.
