Abstract

Within the last years a variety of pulse sequences have been published which visualize musculoskeletal tissues such as menisci, tendons, or ligaments with positive contrast despite their relatively short T2-values. For optimization of sequence parameters by numerical simulations based on Bloch’s equations, knowledge of tissue relaxation times is essential. So far there has been no comprehensive MRI study regarding the systematic measurement of their inherent relaxation properties. Therefore, the purpose of this study was to exemplarily quantify the T1lower case Greek rho, T1, T2, and T2* relaxation times of rapidly relaxing tissues in the human knee joint at 3T in an acceptable examination time.
