Interpretation of spinal MR images in relation to tissue parameters.
When relaxation parameters of tissues are known, selection of adequate instrumental parameters in magnetic resonance imaging is possible. The signal strength of various tissues is defined by proton density, T1 and T2. The calculation of this signal strength is given. The advantages of multiple echoes and the reason why they are used, are mentioned.
