CTICasesRight Lower Lobe Lung Cancer

Imaging findings
Cardiac MRI scout and quick breath-hold sequences incidentally reveal a mass in the superior segment of the right lower lobe. Retrospective review of a prior cardiac PET scan, which had been read as normal by cardiology, shows intense FDG uptake in this pulmonary nodule, and subsequent chest CT confirms a highly suspicious lung mass in a smoker.
Key takeaways
Non-cardiac incidental findings, including lung cancers, are frequently visible on the scout and localizer images of cardiac MRI or PET protocols. It is essential to carefully review all captured anatomy, and institutions should establish protocols to store and review attenuation correction CT scans on PACS to avoid missing clinically significant extracardiac pathology.
