Figure 5.

Quantitative mapping of UTE-T₁ parameter at different undersampling levels in four representative ROIs. A representative region is chosen from each group, namely tendon (patellar tendon), cartilage (anterior femoral cartilage), ligament (posterior cruciate ligament), and meniscus (posterior lateral meniscus). The T₁ quantification values ranged between 500 to 1000 ms. The parameter maps show high correlation between different undersampled maps except posterior lateral meniscus, with values between 900 and 800, a margin of 100 ms.
