The subtraction between minimum TE1 (~50-200 s) and longer TE2 (>~5ms) images was typically performed to provide a better contrast from the deeper layers of cartilage. Here, we show that decreasing TE is more critical to enhance the image contrast of the deeper layers of articular cartilage rather than minimizing TE1 when the subtraction method is used with UTE imaging. This was demonstrated by simulation and UTE imaging.
