Coherent results obtained by ex vivo and in vivo measurements allow the translation of biomarker findings from studies of tissue specimens (ex vivo) to those of patients (in vivo), and therefore it is important to establish how well correlated these metabolic profiles are. Such correlation has been evaluated for brain tumors, prostate cancer and cervical cancer, but without comparison of ovarian tumors. In this study we try to investigate the relationship between the Cho/Cr from in vivo MRS and the Cho/TSP of ex vivo MRS from tissue samples and the potential to bridge molecular and imaging diagnostics.
