Correct!
2. Chest CT
Chest CT is reasonable as the patient appears to have a respiratory illness, but with few, and very-nonspecific, chest radiographic findings, and no clinical data to indicate an etiology. Chest MRI can be useful in selected circumstances, such as characterization of thymic lesions, but has little value for lung parenchymal assessment. Echocardiography is not unreasonable, but probably unnecessary as the patient is young and is not displaying features that suggest myocarditis or cardiac failure. Repeat chest radiography is unlikely to yield additional information to that already known through the 2 previous chest radiographs. Bronchoscopy may play a role in this patient’s assessment, but is premature at this point; chest CT may provide information to direct any tissue sampling procedures and should be performed first.
