Reproducibility of T2 relaxation time mapping in a phantom and human knee articular cartilage.
OBJECTIVE To quantify the reproducibility of knee articular cartilage T2 across a wide range of MR systems. MATERIALS AND METHODS The reproducibility of T2 relaxation time mapping was assessed by measuring the knee of a volunteer (n1.5 T = 22, n3T = 13) and a System Standard 130 phantom (n1.5 T = 19, n3T = 12) in 38...
