摘要:
 【摘 要】 目的:探讨肺混合性磨玻璃结节能谱计算机断层扫描成像(CT)特异性征象,通过对各种结节成分和征象的分析对肺微浸润癌(MIA)、浸润性腺癌(IPA)及肺结核腺泡结节(AN)进行鉴别诊断。 方法:回顾性分析156例肺混合磨玻璃结节及肺结核腺泡结节患者的能谱CT扫描图像及临床资料,并结合病理结果进行对比讨论。 结果:156例患者共有221个结节,均经过手术及送病理检查,包括62个MIA、76个IPA、78个AN、3个硬化性血管瘤及2个炎性假瘤。其中,MIA组结节CT值较低,约为(-221±101) HU,其征象主要为空泡征,占45.16%;IPA组CT值较MIA组高,约为(-102±54) HU,主要征象为分叶征,占47.36%;AN组CT值最高,约为(-40±27) HU,CT征象结节边缘平滑,占70.51%。3组病例CT值及CT征象存在统计学差异(P<0.05)。 结论:能谱CT形态学特征能在一定程度上鉴别MIA、IPA及AN,为临床早期诊疗不同疾病提供相关依据。
Abstract:
 Abstract: Objective To investigate the specific signs of energy spectrum computed tomography (CT) of pulmonary mixed ground-glass nodules, and to perform a differential diagnosis of minimally invasive adenocarcinoma (MIA), invasive pulmonary adenocarcinoma (IPA) and alveolar nodules (AN) based on the components of nodules and CT signs. Methods The CT scan images and clinical date of 156 patients with pulmonary mixed ground-glass nodules and AN were retrospectively analyzed and compared with the pathological results. Results A total of 221 nodules were found in 156 patients. All patients underwent surgery and pathological examination. The nodules include 62 MIA, 76 IPA, 78 AN, 3 sclerosing hemangioma and 2 inflammatory pseudotumor. The CT value of the nodules was found to be the highest in AN group, about (-40±27) HU, followed by IPA group and then MIA group, about (-102±54) and (-221±101) HU, respectively. The main CT sign in MIA, IPA, and AN groups was vacuoles (45.16%), lobulated (47.36%), and smooth margin (70.51%), respectively. Statistical differences were found in CT values and CT signs among the 3 groups (P<0.05). Conclusion The morphological feature of energy spectrum CT can identify MIA, IPA and AN, providing relevant evidences to the differential diagnosis and treatment.
