Abstract
A technique is demonstrated to obtain interleaved proton (^1^H) and ^1^Hโdecoupled phosphorus (^31^P) spectra of human brain using 2D CSI. A modified commercial fullโbody imager and a dualโtuned birdcage headโcoil were employed. Because proton relaxation times are shorter than those of phosphorus, TR(^1^H) can be chosen to be shorter than TR(^31^P), thus permitting a ^1^H acquisition to be inserted in each ^31^P cycle. The scheme results in significant time savings as both CSI data sets are obtained concurrently with patient loading, coil tuningi, shimming, and imaging needed to be done only once.
