Abstract
Generating T~2~ maps in magnetic resonance microimaging is often complicated by the self‐diffusion of water molecules. A modification of the standard spin‐echo pulse sequence is proposed which minimizes this effect. Experiments with doped water confirmed that the T~2~ values obtained with the modified sequence were equal within the experimental error to the value obtained by the spectroscopic Carr‐Purcell‐Meiboom‐Gill method. The applicability of the technique is demonstrated by generating T~2~ maps of porcine articular cartilage. Key words: MR microimaging; relaxation; diffusion; cartilage.
