Abstract
To determine whether dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) quantitative parameters increase the detectability of MRI-invisible residual cervical cancer after conisation. This retrospective study included 59 patients with MRI-invisible cervical cancer, but positive conisation pathology. Thirty-five patients were confirmed to have residual cervical cancer, and 24 patients showed non-residual cervical cancer. DCE-MRI quantitative parameters were calculated in the anterior or posterior cervix according to the conisation position. Receiver operating characteristic (ROC) analysis was used to find the threshold of DCE-MRI parameters in differentiate residual cervical cancer patients from non-residual cervical cancer patients after conisation. For patients with residual cervical cancer, the Ktrans and Ve values were significantly higher than in their counterparts with non-residual cervical cancer (0.610±0.395 versus 0.366±0.305/min, p=0.013; and 0.703±0.270 versus 0.540±0.280%, p=0.028; respectively). The Ktrans showed the highest area under the ROC curve (AUC) of 0.705 (p=0.004) with a sensitivity of 67.6% and specificity of 68%. DCE-MRI quantitative parameters increased the detectability of MRI-invisible residual cervical cancer after conisation.
