摘要
目的分析螺旋cT及MRI在孤立性肺结节诊断中的价值。方法选择孤立性肺结节患者70例,均接受螺旋CT及MRI检查,分析肺结节螺旋CT及MRI特征,分析螺旋CT及MRI单独应用及联合应用的诊断准确性及特异性。结果单独应用螺旋CT、MRI及两者联合应用对孤立性肺结节诊断敏感性分别为86.96%、82.61%和91.30%,特异性分别为66.67%、58.33%和75.00%,三者对孤立性肺结节诊断敏感性及特异性比较差异均无统计学意义(P〉0.05)。结论孤立性肺结节的螺旋cT及MRI均具有一定的特征,两种检查方法单独应用及联合应用均具有较高的诊断敏感性及特异性。
Objective To analyze the value of spiral CT and MRI on the diagnosis of solitary pulmonary nodules. Methods Seventy patients with solitary pulmonary nodules were chosen, and they all underwent spiral CT and MRI examination, the spiral CT and MRI characteristics of pulmonary nod- ules were analyzed. The diagnostic accuracy and specificity of single use of CT or MRI and combined use of CT and MRI was analyzed. Results The diagnosis sensitivity of spiral CT, MRI and their combined use for solitary pulmonary nodules were 86. 96% , 82.61% and 91.30% , and the specificity were 66. 67% , 58.33% and 75.00% , there were no significant differences in diagnostic sensitivity and speci- ficity of pulmonary nodules among the three methods (P 〉 0. 05 ). Conclusions Spiral CT and MRI can show the features of solitary pulmonary nodule, each method and combined use both have high diagnostic sensitivity and specificity.
