The purpose was to evaluate the feasibility of quantitative MRI T mapping based on the quantitative MRI (QRAPMASTER) sequence for the quantitative assessment of knee cartilage. The T values from the phantom study showed excellent correlation between the two techniques (r = 0.998). The cartilage T values exhibited strong correlations (r = 0.867-0.982). Quantitative MRI (qMRI) T mapping can be used as an alternative to multi-echo T mapping, with relatively short scan time.
目的是评估基于定量 MRI（QRAPMASTER 序列）的定量 MRI T 映射技术用于膝关节软骨定量评估的可行性。在体模研究中，两种技术之间的 T 值显示出极好的相关性（r = 0.998）。软骨 T 值之间存在很强的相关性（r = 0.867-0.982）。定量 MRI（qMRI）T 映射可作为多回波 T 映射的替代方法，具有相对较短的扫描时间。
