Abstract：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% .
