Abstract:
Objective To study prospectively HRCT-pathological correlatiion of the small solitary pulmonary nodules in 52 cases.Methods The characterstics of each nodule's margin,internal and peripheral on high resolution CT images was observed with double blind method.Postoperative specimens were fixed in the Heitzman standen method,then specimes were scanned by computed tomography,HRCT signs of nodule were also viewed at same way.Results The results showed :the diameter and distribution of benign and malignant pulmonary nodules was not obviously;the density of benign nodules was more homogeneous than that of malignant nodules.The margin of malignant had slight lobulation in 51%;Halo sign and the peripheral pulmonary emphysema was showed in benign nodules. Conclusion HRCT is of important value to show internal low attenuat of the malignant nodules (diamter
