摘要：

An extension of the solid-state nuclear magnetic resonance (NMR) imaging based on magic angle in the rotating frame (MARF) line narrowing approach is presented. The modified magic angle in the rotating frame imaging sequence is able to yield T-1p maps of large band polymers with remarkable contrast sensitivity and without contrast parameter alteration referable to the narrowing procedure,This last feature is examined closely in order to outline the actual effectiveness of the method. Further experimental details, especially regarding probe coil design, recently improved, are discussed and some new results are presented. (C) 1998 Elsevier Science Inc.
