ABSTRACT

Introduction: The main function of articular cartilage is the absorption and redistribution of biomechanical forces applied with daily activities to the joint. Using sequences such as T2 mapping, it is possible to detect changes in the cartilage properties that occur when receiving compression force, which influences the relaxation time measured in this sequence.
Objective: To evaluate the ability to detect arthroscopically defined cartilage lesions in the retropatellar region with the T2 mapping sequence.
Method: Diagnostic study, observational, transversal and retrospective test.
Results: The sensitivity and specificity calculated for the sequence of T2 mapping was of 92.6% and 93.3%, respectively, which was higher when compared with the calculated one of the conventional protocol, where a sensitivity of 87.4% and a specificity of 91.3% was obtained. The positive predictive value and negative predictive value of the study sequence was 92.6% and 93.3%, respectively.
Conclusion: T2 mapping is a sequence that provides valuable information to the conventional knee protocol. It has the ability to detect lesions that may not be seen in conventional morphological sequences.
