颈部影像报告和数据系统在MRI诊断早期单纯黏膜型鼻咽癌局部复发中的应用
Application of neck imaging reporting and data systems in MRI diagnosis of early exclusive mucosal local recurrent nasopharyngeal carcinoma
摘要
Abstract
Objective:To evaluate the diagnostic value of the neck imaging reporting and data systems(NI-RADS)MRI in exclusive mucosal local recurrent nasopharyngeal carcinoma(EMLRNPC)and mucosal posttreatment changes(MPTC),and attempted to propose adding qualitative diffusion-weighted imaging(DWI)criteria for the focal mucosal abnormality in NI-RADS MRI lexicon.Materials and Methods:From February 2015 to February 2023,totally 21 cases of EMLRNPC and 29 cases of MPTC confirmed by pathology or imaging follow-up were retrospectively enrolled.Two radiologists independently evaluated the MRI findings and assigned a NI-RADS MRI category in the first step,then reevaluated with the adding qualitative DWI criteria and assigned a modified NI-RADS MRI category in the second step.All images were reevaluated by the senior radiologist in the same steps after three months.Inter-and intra-reader agreements were assessed with Cohen's Kappa test.Receiver operating characteristic curves were generated to assess the diagnostic values of the two NI-RADS categories between EMLRNPC and MPTC.Area under the curve(AUC)was compared by DeLong's test.Results:Inter-and intra-reader agreements were 0.69 and 0.88 for NI-RADS MRI categories,and 0.83 and 0.96 for modified NI-RADS MRI categories.In differential diagnosis of EMLRNPC and MPTC,the AUC,sensitivity,specificity of NI-RADS MRI were 0.845[95%confidence interval(CI):0.715-0.932],100.0%(95%CI:83.9%-100.0%),69.0%(95%CI:49.2%-84.7%),and of modified NI-RADS MRI were 0.966(95%CI:0.871-0.997),100.0%(95%CI:83.9%-100.0%),93.1%(95%CI:77.2%-99.2%),respectively.There was statistical difference between the AUCs of two categories(Z=2.985,P=0.003).Conclusions:For both NI-RADS MRI and modified NI-RADS MRI which adding the qualitative DWI criteria,the differential diagnostic value of EMLRNPC and MPTC are great,while the consistency and diagnostic performance are stronger for the modified NI-RADS MRI.关键词
