| ［摘要］ 目的 总结分析肺内孤立性炎性结节的CT形态学表现和CT灌注成像图像特征，以提高孤立性炎性结节的CT诊断正确率。方法 选取16例经病理证实或经临床短期随访观察病变消失或明显缩小的肺内孤立性炎性结节的高分辨CT影像资料，计算动态增强曲线参数。全部患者均行16层螺旋CT平扫及动态增强扫描。结果 结节最大者直径约2.9 cm，最小者直径约1 cm。结节形态为圆形或类圆形。结节边缘光滑清晰者6例，边缘模糊者10例；4例有浅分叶，余无分叶。所有结节周围均无卫星灶、血管集束，所有结节内均无钙化灶。15例CT灌注成像图像上时间－密度曲线为速升速降型，1例为缓升缓降型。结论 结合CT形态学和灌注成像图像，可明显提高肺内孤立性炎性结节的CT诊断准确率。 |

| ［Abstract］ Objective To evaluate the CT diagnostic findings of inflammatory solitary pulmonary nodule to improve diagnostic ability.Methods The CT imaging findings of 16 patients with inflammatory solitary pulmonary nodules confirmed by histology and clinical history were analyzed.Sixteen patients underwent high-resolution plain scan and dynamic contrast-enhanced CT.Results The diameter of the largest nodule was 2.9 cm,the diameter of smallest nodule was 1 cm.The nodules were round and oval. Six nodules had well-defined margin and 10 nodules coarse margin.Four nodules had small lobular appearance.No nodule had satellite lesion and vascular convergence and calcification. The time density curve (TDC) of 15 nodules increased rapidly to the peak height and then declined quickly,the TDC of 1 nodule increased moderately and maintained relatively constant CT values.Conclusion The combination of the morphological and functional imaging diagnosis can increase the rate of correct diagnosis of inflammatory solitary pulmonary nodules. |
