The main objective of our work is to analyze and correlate image findings betweenTrueFISP and T2-Mapping sequences in 1.5-Tesla magnetic resonance (MR), in order toevaluate patellar cartilage disease in symptomatic patients. In addition, we assess T2-Mapping sequence to detect early lesions in the patellar cartilage, for so include it inthe usual protocol of MR and to enhance the diagnostic performance.

This study has been developed based on a protocol previously established at ourhospital by Radiology and Traumatology services. This is a retrospective study in which we evaluate MR imaging of patients whocomplained for knee pain within at least 3 months, derived from Traumatology servicewith clinical suspicion of patellar chondropathy. There were excluded those patientsaffected by previous trauma or surgical procedures on the same knee. Among the studied patients there was carried out an MR from the affected knee, withan 1.5T magnets and knee antenna, acquiring...

Out of the 50 original knee MR, 47 knee MR were analyzed (N=47), 27 right knees and20 left knees. Moreover, 14 patients had both knees assessed. Within all of ourpatients there were 12 men and 21 women, with. 46,25 years of average age (17-70years) and an average BMI of 27,7 (21-37). After concluding the analysis, we obtained these results: - PATELLA: T2-Mapping quantitative values at patellar cartilage (average T2-relaxation time), wereoutside the considered normal limits (<;28,3 & >; 41,2) within all patellar areas, exceptfor the...

After analyzing the results obtained in our study the main conclusion was that T2-Mapping sequence allows the detection of chondral lesions that would have passedundetected with only morphological sequences such as TrueFisp. This may lead to anearly diagnosis and allowed the traumatologist to start an adequate and specifictreatment which could determine a significant improvement in the evolution andprognosis of this condition. Moreover, interobserver agreement gradation in T2-Mapping femoral assessment and patellar damage level evaluation with Outerbridgeclassification was satisfactory, and also highly successful at focal lesions...
