By In vivo 31P MRS it is possible to observe the resolved signals of some key lipid and high energy metabolites and therefore this is an important technique to study tumor biology, to evaluate treatments and to identify diagnostic biomarkers. For studies of brain tumors it is also relevant to be able to perform localized 31P MRS of orthotopically growing tumors in the brain of mouse. In this work we demonstrate that 31P MRSI of high quality can be obtained of 4 different human glioma growing in the mouse brain.
