螺旋高分辨率CT对肺内结节定性诊断价值

The Value of High Resolution Spiral CT in Differentiation of Pulmonary Nodules

目的 评价螺旋 高分辨率CT扫描 (HRCT)对肺内孤立结节性病灶 (SPN)定性诊断的价值。方法 收集 35例肺内结节病变 ( 2 5cm) ,术前做了常规螺旋CT扫描与病灶局部HRCT扫描 ,有手术、病理结果 ,重点对病灶位置、病变形态、大小、边缘、内部结构等征象的显示率进行统计、比较、分析。结果 与常规螺旋CT扫描比较 ,HRCT扫描在显示病变特异性征像 (病变轮廓、病灶内部结构等 )方面敏感性为 90 %以上。

Objective The purpose of this study was to evaluate the value of high resolution spiral CT in differentiation of solitary pulmonary nodules (SPN). Methods 35 patients with pulmonary nodules (diameter is approximately 2.5cm) were examined with spiral CT and HRCT before operation. The location,size,edge and texture of the lesions were recorded and analyzed. All cases were confirmed by surgery and pathology. Results Contrasting to conventional spiral CT,the sensitivity of HRCT in demonstrating the characteristic signs (such as the edge and texture of those nodules) is above 90%. Conclusion HRCT has great value in differentiation of pulmonary nodules. [
