2、8例,炎性結(jié)節(jié)1o例,結(jié)核球12例,術(shù)前均行CT平掃及注藥后30s,1rain,2rain,3min,4min,5rain,6rain的動(dòng)態(tài)增強(qiáng)掃描.根據(jù)病灶平掃CT值及不同時(shí)間增強(qiáng)掃描CT值,做出不同病變CT值的時(shí)間一密度曲線.結(jié)果小肺癌與結(jié)核,炎癥的平掃CT值無顯著差異.結(jié)核球的強(qiáng)化程度明顯低于小肺癌和炎性結(jié)節(jié),但炎性結(jié)節(jié)與小肺癌的CT強(qiáng)化程度無顯著差異.小肺癌,炎性結(jié)節(jié)和結(jié)核球三種病變增強(qiáng)后的時(shí)間一密度一曲線形態(tài)和強(qiáng)化形式不同.結(jié)論動(dòng)態(tài)增強(qiáng)CT掃描對肺內(nèi)孤立性小結(jié)節(jié)鑒別診斷有一定意義.[關(guān)鍵詞]硬幣病變,肺;體層
