PDFAbstract
Objective The aim was to explore the clinical value of T2-mapping in the quantification of degenerative cartilage change at the knee. Methods The study group consisted of 46 patients (26 male and 20 female with average age of 56 years) who underwent MR imaging of knee joint. MR imaging was performed at 3.0 T by using a routine protocol with the addition of an axis T2-mapping sequence. The T2 values In four knee cartilage compartments (the medial and lateral femur and patella) was measured respectively. Results All cartilage compartments showed significant (P<0.05) increase in T2 values between OA group and normal group, but no significant (P>0.05) were found between mild OA group and severe OA group. Conclusion Femoral and patella cartilage T2 values increase with the severity of OA, MRI T2-mapping is valuable for diagnosis and monitoring osteoarthritis.
