The low (1.1%) natural abundance of 13C often requires administration of supplementary labeled compounds to obtain adequate signal strength. Only certain storage compounds that are rich in carbon, such as triacylglycerols or glycogen, can be directly detected by 13C MRS unless small-bore and high...
