A Current Review of the Meniscus Imaging: Proposition of a Useful Tool for Its Radiologic Analysis

Figure 7

Radial tear involving the peripheral aspect of the meniscus. (a) Coronal T2 FSE Fat Sat MRI shows the vertical hyperintense signal (arrow) extends to both articular surfaces of the posterior horn of the medial meniscus; (b) Sagittal T2 FSE Fat Sat MRI shows the cleft sign of a radial tear; (c) three-dimensional diagram showing a radial tear involving the peripheral aspect of the meniscus; (d) arthroscopic view of the radial tear; (e) Coronal T2 FSE Fat Sat MRI: a part of the medial meniscus is not identified on the coronal image due to a large radial tear (arrow); (f) Sagittal T2 FSE Fat Sat MRI shows the large radial tear (arrow); (g) axial reconstruction showing the large radial tear (arrow) extending from the free edge into the posterior horn; (h) arthroscopic view of the large radial tear.
