Abstract:
Objective To investigate the relationships between baseline R2? of blood oxygenation level-dependent magnetic resonance imaging(BOLD-MRI) and Semi-quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) in cervical cancer,to lay a foundation for the further development of assessing tumor hypoxia techniques. Methods Twenty-four patients with cervical cancer were subjected to DCE-MRI and BOLD-MRI before treatment,Semi-quantitative parameters(SI-I、MER、Tmax、IAUC) of DCE-MRI and the baseline R2?of BOLD-MRI produced by special post-processing softwares,the relationships between baseline R2?of BOLD-MRI and Semi-quantitative parameters of DCE-MRI were analyzed. Results Significant positive correlations were observed between baseline R2?and Tmax(r=0.423,P=0.014),there were no correlation between baseline R2? and SI-I、MER or IAUC(P>0.05). Conclusion Semi-quantitative parameters of DCE-MRI and baseline R2? of BOLD-MRI respectively reflected the oxygenation of tumor in different principle. The combined use of the above parameters is expected to improve the performance for defining tumor hypoxia.
