Also unlike X-rays, an MRI shows more than just bones and that is why it is particularly helpful for a meniscus tear, since the meniscus is cartilage and doesnt show up in an X-ray. MRI is also useful in identifying concomitant knee pathology. /A << / 30 0 obj The brightening of the tissue on T1 allows us to both see more lesions and make a more accurate diagnosis. 17 0 obj 0 -1.455 TD 2011-07-15T14:01:41-07:00 324 0 l L/1Kb/8AI2P/ALJ8Vd9Sl/6lN/8AkbH/ANk+Kplb6t5htYUt7fQLiOKMcURZo6Af9I2Kqn6e8z/9 Adobe InDesign 6.0 Lay the subject on his/her back with his/her knee bent to 90 degrees.Sit lightly on the persons foot and wrap your fingers around to the back of his/her knee.Pull the tibia forward towards you to assess how much motion there is.If the ACL is intact, there should be very little motion with a firm end feel.More items
