目的：探讨周围型小肺癌在HRCT及多层螺旋CT强化扫描中的影像学表现及HRCT等技术在该疾病诊断中的价值。方法搜集经手术或穿刺病理证实的周围型小肺癌（直径≤3cm ）52例，全部型 H RC T 扫描，分析其各种C T征象。其中29例行多层螺旋CT强化扫描，对病灶强化前后CT 值增幅特点进行分析。结果 HRCT 表现①分叶征92.3％）；②毛刺征（86．5％）；③胸膜凹陷征（78．8％）；④血管集束征（53．8％）；⑤支气管充气征及空泡征（34．6％）；⑥棘突征（36．5％）⑦磨玻璃样密度（11．5％）；⑧钙化（9．6％）。强化前后C T 值增幅20～30 H U占20．6％，增幅30～65 H U占72．4％，增幅＞65HU占7％。结论 HRCT及多层螺旋扫描是周围型小肺癌诊断中重要的检查方法，诊断可靠，正确率达93％。

Objective To explore the imaging manifestations of peripheral small lung cancer on high resolution CT and MSCT strengthened scanning and their diagnostic value for this disorder .Methods The authors collected 52 patients with pathologicallyproved small peripheral lung cancer (than 3 cm in diameter) .All cases were scanned by high resolution CT and all kinds of CT signs were analyzed .MSCT strengthened scanning was done in 29 patients and the signs of increasing range of CT value in pre‐and post‐reinforcement were analyzed .Results The manifestations of high resolution CT scan‐ning included:① lobulation sign (92 .3% );② spicule sign (86 .5% );③ pleural indentation sign (78 .8% );④ vascul‐arnotch sign (53 .8% );⑤sign of air bronchus and vacuole (34 .6% );⑥spinose processus (36 .5% ) ⑦ milling glass dens (11 .5% );and ⑧ calcification (9 .6% ) .The increasing range of CT value in pre‐and post‐reinforcement was 20~30 HU (20 .6% ) and 30~65 HU (72 .4% ) ,respectively ,with amplification more than 65 HU( 7% ) .Conclusion High resolu‐tion CT and MSCT strengthened scanning are important methods in the diagnosis of peripheral small lung cancer ,which are reliable ,w ith accuracy up to 93% .
