[CT images in differentiating tuberculous nodules from lung cancers with diameters less than 2 cm]
Objective:
To find out the CT characteristics of tuberculous nodules and lung cancers with diameters less than 2 cm, and to evaluate their value in differentiating the two diseases.
Method:
The CT images in thirty patients with tuberculous nodules and forty lung cancer patients with lesions less than 2 cm in diameter were compared.
Results:
Smooth or clear edge, non-lobulation, small cavity, calcification, pleural thicking and adhesion, satellitic nidus and perifocal inflammation were found predominant in tuberculous nodules with short-term dynamic changes in shapes, while shaggy border, shallow lobulation, vacuolus sign, air-bronchogram and typical pleural indentation were predominant in lung cancers without dynamic changes in shapes.
Conclusion:
Thin-slice CT scanning can provide useful images, which by short-term observations are important for differentiating these diseases.
