62-year-old man with history of oropharyngeal cancer, treated by chemoradiation therapy

Caption

Contrast-enhanced multiphase DECT of chest performed for surgical planning. Axial image from iodine concentration map, reconstructed from equilibrium-phase acquisition, shows thin ringlike peripheral high iodine concentration, involving nodule’s entire circumference. Nodule underwent resection, revealing oropharyngeal carcinoma metastasis. Case represents true-positive example of using ringlike peripheral high iodine concentration for diagnosis of pulmonary metastasis.
