ABSTRACT
Objective To evaluate the detection rate of multi-slice spiral CT (MSCT)signs and the clinical value of multi-planar reconstruction (MPR)in T1a and T1b peripheral lung cancer patients.Methods Eighty-seven cases with peripheral lung cancer proved by pathology were collected.The cases were divided into T1a and T1b group based on the TNM classification.The MSCT and MPR images were compared between the two groups.Results (1)Detection rate of the deep sublobe sign,spinous process sign, short spiculated sign,pleural indentation sign,vascular convergence sign,multi-nodule accumulation sign,vacuole sign and air bron-chogram sign,were 1 1.4%,20.0%,31.4%,60.0%,25.7%,45.7%,42.9% in T1a group and 42.3%,36.5%,57.7%, 80.8%,5 1.9%,25.0%,21.2% in T1b group,respectively.The difference were all statistically significant (P < 0.05)between T1a and T1b group except that of the spiculated sign (P = 0.098).(2)The detection rate of the sublobe sign,spinous process sign, spiculated sign,pleural indentation sign and vascular convergence sign were higher on MPR images than on axial thin-slice images in both T1a and T1b group.Conclusion The detection rate of the tumor-lung interface’s signs are lower in T1a than in T1b,the detec-tion rate of internal structure signs of the tumor are higher in T1a than in T1b in peripheral lung cancer patients.MPR has important value in early diagnosis of peripheral lung cancer.
