Single- and Bicomponent Analyses of T2 Relaxation in Knee Tendon and Ligament by Using 3D Ultrashort Echo Time Cones (UTE Cones) Magnetic Resonance Imaging

Figure 3

Selected 3D UTE Cones images and region-of-interest (ROI) shown with red lines in patella tendon (PT) (a), posterior cruciate ligament (PCL) (c), and anterior cruciate ligament (ACL) (e), as well as single- and bicomponent fitting (b, d, f) of interleaved multiecho UTE image acquired at TE (0.032/4.4/20/40 ms, 0.4/6.6/25/50 ms, 0.8/1/30/60 ms, and 2.2/16/35/70 ms of a 29 years old male volunteer). All bicomponent fitting shows superior over single-component fitting. Dashed lines represent the estimated T2 curve and solid black circles represent the data points.
