Complex confounder-corrected R2* mapping for liver iron quantification with MRI.

Objectives: MRI-based R2* mapping may enable reliable and rapid quantification of liver iron concentration (LIC). However, the performance and reproducibility of R2* across acquisition protocols remain unknown. Therefore, the objective of this work was to evaluate the performance and reproducibility of complex confounder-corrected R2* across acquisition protocols, at both 1.

Indirect soft-tissue and osseous signs on knee MRI of surgically proven meniscal tears.

Objective: The purpose of this study was to determine the frequency of abnormal MR signal intensity in soft tissues and osseous structures in association with surgically proven meniscal tears.

Materials And Methods: Seventy patients underwent 1.5-T MRI of the knee and arthroscopy within 3 months.
