Objective: To investigate the value of magnetic resonance imaging (MRI) in parametrial invasion of cervical cancer. Materials and Methods: Fifty-eight consecutive patients with histopathologically confirmed cervical cancer were collected. MRI ifndings were compared with the pathologic ifndings in all cases. The parametrial invasion was evaluated in the following four groups, T2 weighted imaging (T2WI), T2WI combined with diffusion-weighted imaging (DWI), T2WI combined with contrast enhancement and T2WI combined with DWI and contrast enhancement. Results:Among these 58 patients, 8 patients had parametrial invasion. The sensitivity, speciifcity, positive predictive value, negative predictive value and accuracy of T2WI were 87.5%, 90.0%, 58.3%, 97.8%, 89.7%. Those of T2WI combined with DWI were 87.5%, 96.0%, 77.8%, 98.0%, 94.8%. Those of T2WI combined with contrast enhancement were 62.5%, 100.0%, 100.0%, 94.3%, 94.8%. Those of T2WI combined with DWI and contrast enhancement were 87.5%, 100.0%, 100.0%, 98.0%, 98.3%. Conclusions:T2WI combined with DWI and contrast enhancement is superior to other three groups in the evaluation of parametrial invasion.
