LAVA序列增强扫描显示在宫颈癌淋巴结转移判定中的应用

Application of LAVA Sequence Enhanced Scan Display in the Determination of Cervical Lymph Node Metastasis

目的探讨腹部容积快速三维成像(LAVA)序列增强扫描显示在宫颈癌淋巴结转移判定中的应用。方法统计分析2011年3月至2014年10月我院放射科收治的宫颈癌患者72例的临床资料。结果 72例患者576组淋巴结将1518枚淋巴结清扫了出来,其中术后病理检查证实20例患者42组淋巴结有66枚淋巴结为阳性,分别占总数的27.8%、7.3%、4.3%;病理检查LAVA序列横断面上平均短径阳性肿大淋巴结(12.4±5.6)mm显著长于阴性(8.3±2.5)mm(P<0.05),不均匀强化比例87.5%(28/32)显著高于阴性53.8%(28/52)(P<0.05);短径对淋巴结转移的预测价值显著优于长径(P<0.05)。结论 LAVA序列增强扫描显示在宫颈癌淋巴结转移判定中具有较高的应用价值。

Objective To investigate the application of liver acquisition with volume acceleration（LAVA） sequence enhanced scan display in the deternfination of cervical lymph node metastasis.Methods The clinical data of 72 cases of cervical cancer patients treated in our hospital Radiology from March 2011 to October 2014 were statistically analyzed, Results 72 cases of patients 576 with lymph node dissection to 1518 out of which pathological examination confirmed that 42 of 20 patients had 66 lymph nodes were positive lymph nodes, 27.8%, 7.3%, 4.3% of the total, respectively; the pathology LAVA the average cross-sectional diameter of the short sequence of positive lymph nodes （12.4 ± 5.6）mm was significandy longer than the negative （8.3 ± 2.5）mm （P〈0.05）, the proportion of heterogeneous enhancement 87.5% （28/32） was significantly higher than the negative 53.8% （28/52） （P〈0.05）; the short diameter predictive value for lymph node metastasis was significantly better than the long diameter （P〈0.05）. Conclusion LAVA sequence enhanced scan display has higher value in the determination of cervical lymph node metastasis.
