Evaluation of Multi-slice CT Post-processing Technique in Diagnosis of Small Peripheral Lung Cancer / 实用放射学杂志

ABSTRACT

Objective To evaluate the value of multi-slice spiral CT(MSCT)post-processing technique in diagnosis of small peripheral lung cancer .Methods CT materials with small peripheral lung cancer in 20 cases were retrospectively analyzed ,after 16-slice spiral CT scanning ,both plain and contrast ,and reconstructed using 1mm slice thickness ,the images were passing on an independent workstation for SSD and MPR technique .Results the images of SSD and MPR could reveal the relation between focus and surrounding organs in different dirctions,also revealed the features of pulmonary carcinoma stereos copically and directly,could show actually lobulated sign ,burr sign,pleural indentation sign and vessel convergence sign with small peripheral lung cancer ,the SSD imaging was superior in judging the presence of the lobulated sign .Conclusion It is very valuable for diagnosis of small peripheral lung cancer that application of SSD,MPR and two dimensional reconstruction。
