Performance of a fast and high-resolution multi-echo spin-echo sequence for prostate T₂ mapping across multiple systems

Purpose To evaluate the performance of a multi‐echo spin‐echo sequence with k‐t undersampling scheme (k‐t T 2 ) in prostate cancer. Methods Phantom experiments were performed at five systems to estimate the bias, short‐term repeatability, and reproducibility across all systems expressed with the within‐subject coefficient of variation (wCV). Monthly measurements were performed on two systems for long‐term repeatability estimation. To evaluate...
