[Possibilities in using a specific pulse sequence (interlocking sequence) to improve the specificity in NMR tomography].

Methods and possibilities of application of a doubled and interlaced pulse sequence ("interlaced sequence") are discussed. This makes it possible to perform contrast variations and pulse sequence variations subsequently, as well as to determine the parameters proton density, T1 and T2. The selectivity of the combination of all three parameters for tissue classification is demonstrated by means of an individual case and seems to promise a higher specificity of MR tomography.
