摘要
[摘要 ] 目的 对 1.5T磁共振不同序列检出妇科肿瘤盆腔淋巴结转移情况进行分析对比。方法 该次研究中，随机选取该院妇科肿瘤盆腔淋巴结转移患者 32例所有患者在手术前实施弥散加权成像（ DWI）、增强扫描（ T1WI+C）、 T1加权序列（ T1WI）、 T2加权序列（ T2WI）序列检查，对所检出的盆腔淋巴结个数及组别分布进行记录。结果 应用 DWI序列检查时，其妇科肿瘤盆腔淋巴结转移的检出率最高，检出率高达 86.4%，与 T1加权序列扫描及 T2加权序列相比差异有统计学意义。 结论 1.5T磁共振在妇科肿瘤淋巴结转移的检查中，应用 DWI序列扫描具有较高的检出率，在其阳性判断的过程中， ADC阀值法与短径法两种方法可以任意的选用一种。

[Abstract] Objective To analyze and compare the detection of pelvic lymph node metastasis in gynecological tumors with different sequences of 1.5T MRI. Methods in this study, 32 patients with pelvic lymph node metastasis of gynecological tumor in our hospital were randomly selected for DWI, T1WI + C, T1WI and T2WI before operation. The number and group distribution of pelvic lymph nodes were recorded. Results when DWI was used, the detection rate of pelvic lymph node metastasis was the highest, 86.4%, which was statistically significant compared with T1 weighted sequence and T2 weighted sequence. Conclusion 1.5T MRI has a high detection rate in the detection of lymph node metastasis of gynecological tumor. In the process of positive judgment, ADC threshold method and short path method can choose one of them.
