目的 探讨动态增强CT扫描对肺部孤立性结节良恶性鉴别诊断的价值.方法 对符合标准的60例肺孤立性结节,先行胸部CT平扫后,以4ml/秒速率注入造影剂后60秒、120秒、180秒、240秒、300秒行薄层扫描,分析其强化值、强化程度及强化形态.结果 恶性结节的强化值为(36.9±15.1)Hu,明显高于良性结节(19.73±17.61)Hu(P<0.01).周围性肺癌的主要强化形态是完全性强化及周围性强化,结核瘤的主要强化形态是无强化及包膜样强化.结论 动态增强CT扫描对孤立性肺结节定性诊断有重要意义,强化值的大小是重要诊断依据.
目的 探討動態增彊CT掃描對肺部孤立性結節良噁性鑒彆診斷的價值.方法 對符閤標準的60例肺孤立性結節,先行胸部CT平掃後,以4ml/秒速率註入造影劑後60秒、120秒、180秒、240秒、300秒行薄層掃描,分析其彊化值、彊化程度及彊化形態.結果 噁性結節的彊化值為(36.9±15.1)Hu,明顯高于良性結節(19.73±17.61)Hu(P<0.01).週圍性肺癌的主要彊化形態是完全性彊化及週圍性彊化,結覈瘤的主要彊化形態是無彊化及包膜樣彊化.結論 動態增彊CT掃描對孤立性肺結節定性診斷有重要意義,彊化值的大小是重要診斷依據.
목적 탐토동태증강CT소묘대폐부고립성결절량악성감별진단적개치.방법 대부합표준적60례폐고립성결절,선행흉부CT평소후,이4ml/초속솔주입조영제후60초、120초、180초、240초、300초행박층소묘,분석기강화치、강화정도급강화형태.결과 악성결절적강화치위(36.9±15.1)Hu,명현고우량성결절(19.73±17.61)Hu(P<0.01).주위성폐암적주요강화형태시완전성강화급주위성강화,결핵류적주요강화형태시무강화급포막양강화.결론 동태증강CT소묘대고립성폐결절정성진단유중요의의,강화치적대소시중요진단의거.
Objective To explore the value of dynamic contrast-enhanced CT for differentially diagnosing benign and malignant the solinary pulmonary nodules.Methods 60solitary pulmonary nodules proved by histopathological examination were cnrolled in this study.Thin-section CT scanning was performed before and 60S,120s,180s,240s,300safter contrast enhancement.Result The enhanced value of malignant nodules(36.9±15.1)Hu was significantly higher than that of benign nodules(19.78± 17.61)Hu(P<O.O1).The surroundings lung cancer's main strengthened shape is the complete strengthening and periphery the strengthening.Tuberculoma's main strengthened shape does not have strengthened and the involucrum type strengthening.Conclusion The enhanced helical CT scans are importance in the diagnosis of Solitary Pulmonary Nodules.
