The
purpose of this study was to examine the utility of DWI-MRI for the
assessment of early response to chemotherapy in patients with advanced lung
cancer by comparing FDG-PET. Twenty-two lung cancer patients received MRI,
FDG-PET, and CT examination before and after 1 cycle of chemotherapy. Progression-free survival (PSF) between
responder and non-responder against chemotherapy was compared by means of %
change of ADC and SUV. Both index
indicated that responder demonstrated significant longer PSF and DWI-MRI will
be a promising tool for the assessment of the early response to chemotherapy.
