Diagnostic Accuracy of 3T MR in Staging of Uterine Cervical Carcinoma
Journal Title: Journal of Medical Diagnostic Methods - Year 2018, Vol 7, Issue 3
Abstract
Objective: We aimed to evaluate the diagnostic accuracy of 3T MRI sequences for staging of uterine cervical carcinoma (CC).Methods: We examined 22 cases of CC by a 3T MRI with T2W single shot turbo spin echo, diffusion weighted imaging (DWI) and post-contrast dynamic T1W images. The quantitative evaluation of dynamic series was also performed. Results: For parametrial invasion, DWI and early phase post-contrast images yielded higher diagnostic accuracy.DWI showed 86% sensitivity, 41% specificity, 80% diagnostic accuracy, 100% PPV, and 70% NPV. Post-contrast early phase images yielded 80% sensitivity, 71% specificity, 77% diagnostic accuracy, 86% PPV, and 62% NPV.T2W sequences showed 73% sensitivity, 71% specificity, 73% diagnostic accuracy, 85% PPV, and 55% NPV. Late phase contrast-contrast images yielded 60% sensitivity, 71% specificity, 64% diagnostic accuracy, 82% PPV, and45% NPV.Conclusion: 3T MRI has high diagnostic accuracy in the preoperative staging of CC especially with D
