摘要
目的评价多层螺旋CT灌注成像在不典型周围型肺癌诊断中的应用。方法回顾性分析12例不典型周围型肺癌利用多层螺旋CT灌注成像的影像表现。结果12例周围型肺癌表现不典型,主要有3种情况:a)周围型肺癌合并肺结核见于4例;b)直径小于3cm非实质性结节灶见于6例;c)单发小片状病灶见于2例。结论周围型肺癌可出现多种不典型征象,认识这些征象对临床诊断及治疗都有重要意义。
Objective To assess the utility of muhislice spiral computed tomogsaphy （MSCT） perfusion imaging in the diagnosis of atypical peripheral lung cancer（APLC） . Methyls Twelve patients with APLC which was confirmed hy surgery or biopsy underwent MSCT perfusion imaging. The imaging findings in all patients were analyzed retrospectively. Results On MSCT perfusion images of 12 patients, the coexistences of two kinds of the lesions which were APLC and pulmonary tuberculosis were found in 4 cases, non - parenchymal nodular foci less than 3.0 cm in diameter were found in 6 cases, and single small patchy foci were found in 2 cases. Conclusion APLC can present various atypical signs on MSCT perfusion images, while the sufficient understanding of these signs is very useful for guiding the clinical diagnosis and treatment of this disease.
