Determining the longitudinal accuracy and reproducibility of T(1) and T(2) in a 3T MRI scanner

PURPOSE: To determine baseline accuracy and reproducibility of T(1) and T(2) relaxation times over 12 months on a dedicated radiotherapy MRI scanner. METHODS: An International Society of Magnetic Resonance in Medicine/National Institute of Standards and Technology (ISMRM/NIST) System Phantom was sca...
