For comparison, subcutaneous fat and lipids in glioblastomas were examined with 1 H MR spectroscopy in vivo and ex vivo .
Fat suppression makes the identification of lipomas simple.
It is suggested that 1 H MR spectroscopy shows no differences in the aliphatic chain length of lipoma and subcutanous fat, whereas lipids in glioblastomas have a much shorter chain length. Chain length of fatty acids in lipoma measured with in vivo MR spectroscopy are in concordance with data from the literature.
