abstract：OBJECTIVE:The water component dominates in in vivo proton (1H) spectroscopy. This consists of a prominent central peak with large "wings," and consequently metabolites that lie on the "wings" become difficult to quantitate. A method has been developed to deconvolve the water component in in vivo 1H spectroscopy, hence ...
