This study determined the value of quantitative transverse relaxation time (T2) mapping as an alternative method to conventional magnetic resonance imaging (MRI) for evaluating the response to concurrent chemoradiotherapy (CCRT) in 27 patients with advanced cervical cancer (CC). Response values were calculated at three time points (before CCRT, 4 weeks after CCRT, and at the end of CCRT) and then compared. The results showed that quantitative T2 mapping can be effectively used for monitoring treatment response during and after treatment, but not for pre-treatment monitoring.
