聚丙烯酰胺水凝胶注射隆乳术后MRI影像特征及其性状相关性.docVIP

聚丙烯酰胺水凝胶注射隆乳术后MRI影像特征及其性状相关性[摘要]目的：探讨聚丙烯酰胺水凝胶注射隆乳术后患者的MRI影像学特征与聚丙烯酰胺水凝胶（PAHG）物理性状之间的相关性。方法： 对83例患者术前行MRI检查，术前对患者的影像学特征进行分类，术中详细记录每种影像学特征在术中对应的PAHG性状。对记录结果进行统计学处理。结果：MRI不同影像学特征与PAHG性状的相关系数等于0.704,P＝0.00（＜0.01）。结论：MRI不同影像学特征与PAHG的性状具有显著的相关性。通过对MRI特征的认识，可以对PAHG性状作出比较准确的判断，有利于对手术风险及预后的估计，进而提高PAHG取出术的准确性和安全性。 [关键词]聚丙烯酰胺水凝胶；隆乳术；MRI [中图分类号]R622R655.8 [文献标识码]A [文章编号]1008-6455（2009）02-0157-04 Research on correlations between MRI signs and PAHG trait of breast augmentation with PAHG ZHANG Zhuo-qi1,LUAN Jie2 （1.Department of Oncological Surgery，the Affiliated Hospital of Hebei University, Baoding 071000, Hebei, China; 2.

We recorded the PAHG trait corresponded to each sign of MRI. Statistical treatment was done to the recoded dada.ResultsCorrelation coefficient between MRI signs and PAHG trait was 0.704（P＝0.00 ＜0.01）.ConclusionsThere has evident correlations between MRI signs and PAHG trait. MRI signs can help us to evaluate the PAHG trait, so as to predict the difficulties of operation and to improve the securities of operation.
