Objectives
To compare three-dimensional (3D) turbo-spin-echo (TSE) isotropic sequences with two-dimensional (2D) sequences in the detection of meniscal tears and compare it with arthroscopic findings which was the gold standard method.
Background
MRI is the most common, noninvasive, and accurate imaging modality for knee injuries. The purpose of the study was to compare 3D TSE isotropic sequences and conventional 2D TSE at 3T MRI in the detection of meniscal tears.
Patients and methods
This study was a retrospective study on 95 patients [42 (44.2%) females and 53 (55.8%) males] with suspected meniscal injury who had undergone knee 3 T MRI sequences, including a series of 2D conventional sequences with additional 3D isotropic TSE sequence in the period from April 2018 to March 2019.
Results
The sensitivity and specificity of 3D TSE is higher (100 and 100%) compared with 2D TSE sequence (67 and 96%) with statistical significance (P<0.003) in radial tears. For other types of meniscal tears, both 3D TSE and 2D TSE sequences had similar diagnostic accuracy with nonstatistical significance between the sensitivity and specificity of both techniques.
Conclusion
We concluded that 3D TSE is a useful and reliable technique that has a diagnostic performance like the routine 2D TSE MR protocol for detecting meniscal tears at 3 T with superior detection of radial tears.
