【摘要】 目的 探讨MSCT增强扫描及其多平面重建技术对判断鼻咽癌颈动脉鞘区侵犯的价值。 方法 将病理学检验证实的102例鼻咽癌的MSCT平扫、增强及多平面重建的颈动脉鞘区情况进行回顾性对照分析。 结果 平扫显示颈动脉鞘区部分侵犯68例(66.7%)，显示肿物占据11例(10.8%);而MSCT增强扫描及其多平面重建显示颈动脉鞘区部分侵犯46例(45.1%)，肿物占据33例(32.4%)，经统计学检查两者的差异有显著性(P<0.05)。 结论 MSCT增强扫描及其多平面重建技术可以区分颈动脉鞘区是部分侵犯还是肿物占据，因而较MSCT平扫能更准确划分肿瘤的侵犯范围，可以提高鼻咽癌临床分期的准确性。

    【Abstract】 Objective To probe into the technology of MSCT contrast enhancement scanning and Multiplanar reformation which judge nasopharyngeal carcinoma carotid sheath area whiplash being infringed.Methods 102cases of nasopharyngeal carcinoma which were verified by pathology were reviewed and analyzed.Results Plain scanning showed68cases of whiplash district of carotid sheath area being infringed(account for66.7%)and11cases of mass occupied(account for10.8%).But MSCT contrast enhancement and Multiplanar reformation showed46cases of whiplash district of carotid sheath area being infringed(account for45.1%) ......
