Normal ACL presence on MRI and arthroscopy of a 14-years-old female teenager. The ACL was shown on sagittal T1WI (a), coronal T2WI (b), Sagittal PDWI (c), coronal PDWI (d), and axial PDWI (e). It was tilted from the tibial to the condyle and the attachment was inserted from the condyle to the notch with low signal intensity (arrows). The ligament could be displayed completely on one level of the new modified DPP-TSO-Sag-FS-PDWI (arrow on (f)). The normal appearance of ACL was proved on arthroscopy (arrow on (g)).
