Abstract:
Objective To assess the value of diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) in differential diagnosis of neuroendocrine carcinoma of the uterine cervix (NECUC) from other tumors.Methods A total of 12 NECUCs,39 cervical squamous cell carcinomas (SCC) and 21 cervical adenocarcinomas (CA) confirmed by pathology were analyzed retrospectively.All the patients underwent conventional MRI and DWI.The ADC values were measured and compared among NECUC,SCC and CA.Diagnostic performance of ADC was compared using receiver operating characteristic curves (ROC).Results The mean ADC values of NECUC,SCC and CA were (0.66 ± 0.11) ×10-3 mm2/s,(0.86 ± 0.11) × 10-3 mm2/s and (1.04 ± 0.17) × 10-3 mm2 / s,with statistical differences between any two groups (P ＜0.001).The optimal cutoff values of ADC for differentiating NECUC and SCC was 0.681 ×10-3mm2/s with a sensitivity of 94.9％,specificity of 75.0％ and accuracy of 90.2％.The optimal cutoff values of ADC for differentiating NECUC and CA was 0.824× 10-3mm2/s with a sensitivity of 95.2％,specificity of 91.7％ and accuracy of 98.9％.Conclusion The differences of the mean ADC value are helpful for the differential diagnosis of NECUC,SCC and CA.
