MR不同序列对子宫内膜癌盆腔淋巴结转移的诊断价值分析
Analysis on the Diagnostic Value of Different MR Sequences(T1WI,T2WI,DWI)for Pelvic Lymph Node Metastasis of Endometrial Cancer
摘要
Abstract
Objective To analyze the diagnostic value of different magnetic resonance imaging(MR)sequences[T1-weighted imaging(T1WI),T2-weighted imaging(T2WI),diffusion-weighted imaging(DWI)]for pelvic lymph node metastasis of endometrial cancer.Methods A total of 150 patients with endometrial cancer admitted to Zhengzhou Central Hospital from March 2023 to March 2025 were selected as the study subjects.All patients underwent MR examinations with different sequences(T1WI,T2WI,DWI).Using pathological results as the gold standard,the lymph node sizes detected by T1WI,T2WI,and DWI in metastatic lymph nodes,as well as the apparent diffusion coefficient(ADC)values of metastatic and non-metastatic lymph nodes under different b-values on DWI were compared,the diagnostic efficacy of T1WI,T2WI,and DWI for pelvic lymph node metastasis was analyzed.Results Pathological examination of 150 patients with endometrial cancer showed 302 lymph nodes,with diameters ranging from 10 to 25 mm and an average diameter of(17.44±5.81)mm.Among these,there were 104 metastatic lymph nodes(34.44%)and 198 non-metastatic lymph nodes(65.56%).The short diameter of lymph nodes detected by T1W1 sequence was larger than that detected by T2W1 sequence and DWI(P<0.05),but no statistically significant difference showed in the short diameter of lymph nodes detected by T2W1 sequence and DWI(P>0.05).The ADC values of metastatic lymph nodes were higher than those of non-metastatic lymph nodes at different b-values(P<0.05).The diagnostic accuracy,sensitivity,and specificity of DWI for pelvic lymph node metastasis of endometrial carcinoma were higher than those of T1WI and T2WI(P<0.05),there was no statistically significant difference in the diagnostic accuracy,sensitivity,and specificity between T1WI and T2WI(P>0.05).Conclusions DWI demonstrates higher diagnostic accuracy,sensitivity,and specificity for detecting pelvic lymph node metastasis of endometrial cancer compared to T1WI and T2WI,but no significant difference shows between DWI and T2WI in evaluating lymph node size.Therefore,in clinical practice,multiple MR sequences should be used in combination with individual patient conditions to achieve optimal diagnosis of pelvic lymph node metastasis of endometrial cancer.关键词
