摘要
目的研究并分析多层螺旋CT增强扫描与高分辨率计算机体层X线摄影术(HRCT)在周围型小肺癌中的价值与影像学征象。方法 2012年5月至2015年12月收治确诊的62例周围型小肺癌患者,采取随机数字表法将其分为增强组与高分辨率组,每组31例。其中强化组施以多层螺旋CT增强扫描,高分辨率组施以HRCT检查。观察比较两组患者的影像学征象。结果 HRCT组对胸膜凹陷征、血管集束征、空泡征、棘突征、细支气管气相、短毛刺征以及分叶征的检出概率均在一定程度上高于多层螺旋CT增强扫描组,但两者之间各征象的比较差异无统计学意义(P>0.05)。所观察病例中,Ct值的增加幅度处于20~30 HU的患者例数为5例(16.13%),Ct值的增加幅度处于30~65 HU的患者例数为21例(67.74%),Ct值的增加幅度超过65 HU的患者例数为5例(9.68%)。结论在常规CT扫描的基础上,多层螺旋CT增强扫描与HRCT都属于对周围型小肺癌较可靠的诊断方法;其中HRCT对各影像学征象的检出略有优势,而螺旋CT增强扫描后周围型小肺癌Ct值增幅较为明显,具有参考价值。
Objective To analyze the value and features of multislice CT enhanced scan and HRCT in the peripheral small lung cancer.Methods 62 cases of peripheral small lung cancer patients treated from May 2012 to December 2015 were selected. According to random number table method,all the patients in the study were divided into enhanced group with HRCT group,31 cases in each group. Enhanced group patients performed multislice CT enhanced scan,and HRCT group patients performed HRCT examination. Radiographic signs were observed and compared. Results The detection rate of pleural indentation,the vessel convergence sign,vacuole sign,airbronchogram,spiculated sign,lobulated sign on HRCT were higher than those on enhanced enhanced MSCT（ P〈0. 05）. There were 5 cases wich CT value rising 20 - 30 HU after enhancement（ 16. 13%）,21 cases 30 - 65 HU patients（ 67. 74%）,5 cases more than 65 HU（ 9. 68%）. Conclusion On the basis of the conventional CT scanning,MRCT and HRCT scan are reliable methods for the diagnosis of peripheral small lung cancer. HRCT has advantage for the detection of various imaging signs,and peripheral small lung cancer had obvious enhancement. These signs have the reference value.
