| 摘 要： | 目的探讨肺硬化性肺泡细胞瘤（PSP）CT平扫及增强影像学特征。方法回顾分析27例PSP病例的CT特点,并对其中22例PSP及对照组平扫、增强的相对CT值进行分析。结果多数PSP形态规则,以软组织密度为主,部分可见钙化、空气半月征、血管贴边征及晕征,平扫相对CT值为0.77±0.41,小于增强后50 s（1.30±0.43）及90 s（1.45±0.46）,差异均有统计学意义（P < 0.05和P < 0.01）。PSP组与对照组各时间点相对CT值差异均无统计学意义（P>0.05）。结论CT平扫可显示PSP特点,结合增强后病灶强化明显,可助PSP诊断。

| Abstract: | ObjectiveTo investigate the plain CT and enhanced imaging features of pulmonary sclerosing peumocytoma(PSP).MethodsThe CT features in 27 patients with PSP were retrospectively analyzed.The relative CT value of plain CT and enhanced imaging in 22 cases with PSP and control group were analyzed.ResultsThe regular shape, main soft tissue density, partial calcification, air-gap, overlying vessel and halo sign were the main symptoms in most PSP, the relative CT value of PSP was (0.77±0.41), which was less than that after 50 s and 90 s of enhance[(1.30±0.43) and (1.45±0.46)] (P < 0.05 and P < 0.01).The differences of the relative CT value at each time-point between two groups were not statistically significant(P>0.05).ConclusionsThe CT plain scan can show the characteristics of PSP, which combined with obvious enhancement of lesions can help the PSP diagnosis. |
