Abstract

Advances in radiologic techniques are improving the detection and evaluation of the solitary pulmonary nodule. While past chest films are valuable for identifying nodule growth, thin-section CT provides better assessment of calcification and can detect nodules not seen on chest films. Calcification in a central, laminated, or diffuse pattern indicates the nodule is benign. Risk factors for malignancy include nodule size greater than 2 cm; radiologic evidence of growth; and a history of smoking, airway obstruction, or malignancy. If the nodule is uncalcified and is 3 mm or smaller, repeat thin-section CT at 6 months; if it is 4 to 7 mm, repeat CT in 3 months. For nodules of 8 to 30 mm, consider contrast enhancement with CT, MRI, or positron emission tomography. If the nodule shows enhancement, biopsy or removal may be indicated.
