Abstract

Background & Objectives: Knee is the largest synovial joint in the body. Although FSE PD (fast
spin echo proton density) imaging technique for the diagnosis of meniscal tear has replaced CSE PD
(conventional spin echo proton density) technique in many MRI centers, several studies have questioned
the effectiveness of FSE PD technique in diagnosis of meniscal tear. In this study, the diagnostic values
of CSE PD and FSE PD techniques in evaluation of meniscus tear are compared.
Materials: In this study, using CSE PD and FSE PD techniques, MRI was performed on 67 knees of
patients with suspected meniscal tear referring to the MRI Center of Imam Reza Hospital (Kermanshah,
Iran). Diagnostic arthroscopy was also performed for all patients. The data were entered SPSS version
20, and finally the results of MRI reports of the two techniques were compared in evaluation of meniscal
tear taking into account the arthroscopic findings as the gold standard.
Results: According to the results of this study, no significant difference was found in specificity and
positive predictive value of the two techniques. However, the sensitivity and negative predictive values
were significantly different, in such a way that the related values were 97% and 97% in the CSE PD
technique and 69% and 73% in the FSE PD technique, respectively.
Conclusion: Due to low sensitivity and high false negative results, MRI using FSE PD technique is not
recommended as an alternative for CSE PD technique in evaluation of meniscal tear.
