Consistency Analysis of T2 Mapping and 3D-WATSc Techniques in Quantitative Measurement of Knee Cartilage Volume

Motivation: The quantitative measurement of cartilage volume holds significant value for the diagnosis and prognostic assessment Goal(s): To assess the consistency between the knee cartilage volumes obtained from the 3D-WATSc sequence and the T2 mapping sequence. Approach: Based on T2 mapping and 3D-WATSc sequences, semi-automatic segmentation measurements were performed on the cartilage volume of various parts of knee joint in 30 subjects.Test the consistency of cartilage volume between two observers under T2 mapping sequence, as well as between T2 mapping and 3D-WATSc sequences. Results: The consistency of the cartilage volumes of each part measured by 3D-WATSc and T2 mapping sequences was good Impact: The consistency between T2 mapping and 3D-WATSc sequences in quantifying knee cartilage volume is good, and the T2 mapping single sequence provides a reliable scanning scheme for one-stop quantitative analysis of knee joint cartilage morphology and function.
