Correct!
3. High-resolution chest CT (HRCT)
Thoracic MRI and 18FDG-PET scanning typically do not play a role in the evaluation of interstitial lung abnormalities. As noted above, bronchoscopy with transbronchial biopsy is not unreasonable, but is probably premature when non-invasive imaging characterization of the pulmonary process with high-resolution chest CT (HRCT) has not yet been performed. 68Ga-Dotatate scans are typically employed for the evaluation and staging of neuroendocrine malignancies. HRCT may provide information that allows a definitive diagnosis for the findings noted at chest radiography, or at least narrows the differential diagnostic considerations somewhat, and may be able to offer information regarding the best route for obtaining a tissue diagnosis.
