WebThe time parameters T1 and T2 are strongly influenced by the viscosity or rigidity of a tissue. The greater the viscosity and rigidity, the smaller the value for T1 and T2. WebData from the right knee of each participant were collected using a 1.5-T MRI equipped with a single-channel knee coil. T2* values were acquired using a conventional T2* mapping protocol and a radial T2* mapping method. Mean T2* values in the meniscal white zones, meniscal red zones, and total menisci were calculated.
