Amide proton transfer (APT) imaging shows increasing interest in characterization of the brain tumor. The objective of our study is to investigate whether APT imaging can provide useful biomarker to determine treatment responses or resistance of the glioblastoma multiforme (GBM) in chemotherapy. In the present study, we compared two human GBM cell lines derived from the same patient that have same genotype, which is a unique and powerful system to compare directly the APT signal in the setting of temozolomide sensitivity and resistance.
