摘要
目的分析多层螺旋CT(MSCT)结合多平面重组(MPR)技术诊断磨玻璃密度结节样肺癌的影像学表现。方法选择陕西省渭南市第一医院70例有肺部磨玻璃密度结节样患者为研究对象,收集其MSCT影像资料,患者MSCT肺窗显示病灶直径≤2 cm,磨玻璃部分>50%,根据病理学检查结果进行病灶性质划分,观察不同病灶性质(大小、形态、类型、内部、边缘、周围及邻近组织结构、病灶与支气管的关系)患者MSCT结合MPR技术影像学的资料,分析MSCT结合MPR技术在诊断磨玻璃密度结节样肺癌中的价值。结果病理学检查显示浸润性腺癌26例,浸润前病变21例,良性病变23例。浸润性腺癌、浸润前病变和良性病变的病灶类型、病灶位置、病灶形态比较差异均无统计学意义(P>0.05),病灶直径、病灶边缘、空泡征、胸膜凹陷征、血管纠集征和支气管类型比较差异均有统计学意义(P<0.05)。以病理结果为准,MSCT结合MPR技术诊断浸润性腺癌的准确率为96.15%,诊断浸润前病变的准确率为90.48%。结论MSCT结合MPR技术可以较好地显示不同磨玻璃密度结节病灶特征,在诊断浸润性腺癌、浸润前病变中具有较高应用价值。
Objective To analyze the imaging findings of lung cancer with ground-glass nodules diagnosed by multi-slice spiral CT(MSCT)combined with multiplanar reconstruction(MPR)technique.Methods A total of 70 patients with ground-glass opacity nodules in lung in the First Hospital of Weinan in Shaanxi Province were selected as the research objects.Their MSCT imaging data were collected.MSCT lung window showed that diameters of the lesions were not larger than 2 cm and the proportion of ground glass was higher than 50%.According to the pathological examination results,lesions were classified.The imaging findings of MPR MSCT in patients with different lesions(size,shape,type,inside,edge,surrounding and adjacent tissues,relationship between lesions and the bronchus)were observed.The value of MSCT combined with MPR in diagnosis of lung cancer with ground-glass nodules was analyzed.Results Pathological examination showed that there were 26 cases with invasive adenocarcinoma,21 cases with pre-invasive lesions and 23 cases with benign lesions.There were no significant differences in lesion types,lesion locations and lesion morphology among invasive adenocarcinoma,pre-invasive lesions and benign lesions(P>0.05).There were statistical significance in lesion diameter,margin of lesions,vacuole sign,pleural depression sign,vascular gather sign and bronchial types(P<0.05).Pathological results were taken as the standard,the accuracy rates of MPR MSCT for diagnosis of invasive adenocarcinoma and pre-invasive lesions were 96.15%and 90.48%,respectively.Conclusion MSCT combined with MPR can display features of different ground-glass opacity nodular lesions well,which has relatively high application value in diagnosis of invasive adenocarcinoma and pre-invasive lesions.
