Figure 2: Dual echo three-dimensional fat saturation UTE cones MRI of ZCC from a 40-year-old cadaveric knee joint specimen. UTE images were acquired at a series of TEs of 0.1 ms (a), 0.2 ms (b), 0.4 ms (c), 0.6 ms (d), 0.9 ms (e), 2.2 ms (f), and 6.6 ms (g). The eighth image was produced by a subtraction of the seventh one from the first one, wherein the visualization of the ZCC of knee cartilage was improved (arrows) (h). A single-component exponential fitting curve (j) showed a short T2* of 1.16 ± 0.10 ms at ROIs in the ZCC (i), and there was loss of signal with increasing TE. ZCC: Zone of calcified cartilage; UTE: Ultrashort time echo; MRI: Magnetic resonance imaging; ROIs: Regions of interest; TE: Time echo.
