1. Perform unenhanced chest CT
Unenhanced chest CT is typically the diagnostic study of choice when a new indeterminate nodule is encountered in an adult patient. As noted previously, lateral decubitus chest radiography is reserved for assessment of layering pleural effusion (with the affected side dependent) or pneumothorax (with the affected side non-dependent). PET scanning with 68Ga-Dotatate is typically used for the evaluation of neuroendocrine malignancies, and could play a role for this patient if that diagnosis is subsequently confirmed, but is as yet premature. Thoracic MR is not commonly employed for the assessment of new pulmonary nodules; chest CT is generally more rewarding for that application).
