knee meniscus6 [Tear_08] Tear of popliteomeniscal fascicles -06 It is sometimes difficult to identify peripheral longitudinal tears in the posterior horn of the lateral meniscus because of the complex anatomy and posterior attachments of the capsule and popliteomeniscal fascicles. Far peripheral longitudinal tears can be more difficult to detect With an “extra” vertical line or layer in the meniscal periphery, it can be a subtle finding that indicates a tear.. 2021. 10. 9. [Tear_07] Far Peripheral Longitudinal Meniscal Tear -05 On the left image, we can easily see the longitudinal tear, but on the right image it is very difficult to identify peripheral longitudinal tear. Like this, longitudinal tears that occur further peripherally can be more difficult to detect. When the tear extends through the meniscal substance it is readily identified against the contrast afforded by the low signal meniscal tissue. or, Identifica.. 2021. 10. 9. [Tear_06] Far Peripheral Tear Longitudinal Meniscal Tear -04 Here is a full-thickness peripheral longitudinal tear of the posterior horn of lateral meniscus. There is an extra vertical line or layer in the periphery of lateral meniscus, indicative of far peripheral longitudinal tear. The tear is parallel and adjacent to the popliteus tendon. It is sometimes difficult to identify peripheral longitudinal tears in the posterior horn of the lateral meniscus b.. 2021. 10. 9. [Tear_05] Inferior Surface Longitudinal Meniscal Tear -03 Longitudinal tears are diagnosed on MRI by the presence of a vertical line of increased signal intensity contacting the superior, inferior, or both surfaces of the meniscus. The longitudinal tear extends to the inferior meniscal surface and courses parallel to the long axis of the meniscus on corresponding PD FSE axial image. [Tear_04] case demonstrates vertically oriented increased signal inten.. 2021. 10. 9. [Tear_04] Complete Longitudinal Meniscal Tear -02 Longitudinal tears almost always involve the posterior horn in both the medial and lateral menisci. They are diagnosed on MRI by the presence of a vertical line of increased signal intensity contacting the superior, inferior, or both surfaces of the meniscus. MR images showing vertically oriented increased signal intensity contacting both articular surfaces of the body and posterior horn of the .. 2021. 10. 9. [Tear_03] Longitudinal Meniscal Tear -01 Left drawing shows a typical longitudinal tear that divides the meniscus into inner and outer halves, and the right drawing shows the expected appearance of the tear. Longitudinal tear with peripheral vertical orientation through the circumferential collagen fibers. Longitudinal tears run perpendicular to the tibial plateau and parallel to the long axis of the meniscus. Unlike horizontal or radi.. 2021. 10. 9. 이전 1 다음
