Research Abstract

MRI is the best of choice for the evaluation of the human knee cartilage, the studies evaluated by MRI of 3T or over have been reported. We evaluated the t2 values of the human knee cartilage with 1.5T MRI, in which the t2 values of the human knee cartilage were influenced by age, gender, body weight, or BMI. In patients with the early stage of osteoarthritis of the knee, the t2 values of the cartilage were elongated and inhomogeneity of the t2 values of the knee cartilage was also noted on the t2 mapping.
