Usefulness of the oblique view of three-dimensional isotropic T2-weighted fast spin-echo (VISTA) in the evaluation of anterior cruciate ligament reconstruction

Abstract

Background: To compare the diagnostic performance of the oblique sagittal and oblique coronal views of the anterior cruciate ligament (ACL) on three-dimensional (3D) volume isotropic turbo spin-echo acquisition (VISTA) images with two-dimensional (2D) fast spin-echo (FSE) T2-weighted images in the diagnosis of complications in ACL reconstruction.

Materials and methods: This retrospective study included 74 patients. Both sequences were independently interpreted by two radiologists.

Result: There were no statistically significant differences in the sensitivity, specificity, or accuracy between the two images.

Conclusion: The diagnostic performance of the two oblique views on 3D VISTA imaging was comparable to that of 2D FSE.
