[Feasibility of proton magnetic resonance spectroscopy of the myocardium in vivo].

OBJECTIVE

To investigate the feasibility of proton magnetic resonance spectroscopy ((1)H-MRS) of the myocardium in vivo.

METHODS

A total of 100 volunteers were examined with 1H-MRS scan using a 1.5T MR scanner, and the magnetic resonance spectra were analyzed.

RESULTS

All the volunteers completed the examinations, and the spectral peaks were identified with the chemical shifts of water (4.7 ppm), choline (3.2 ppm), creatine (3.0 ppm), and triglyceride (0.9-1.6 ppm), whose presentation ratios were 100%, 86%, 90%, and 98%, respectively. In 86 cases the spectra showed all the chemical shifts. The myocardial metabolite contents were expressed as the ratio of metabolites to water (%), and the contents of choline, creatine, and triglyceride were 1.94%, 1.95%, and 9.41%, respectively.

CONCLUSION

(1)H-MRS can be used in detecting the metabolic products of myocardium in vivo.
