CT scans, including the relation to adjacent anatomic structures, with minimal false-negative rates.     Fig. 2 shows an illustrative case of FFB in the esophagus. Computed tomography scans are valuable in patients presenting with suspected complications, such as soft tissue penetration, and in hypopharyngeal FFBs.   Some studies suggest that ultra-low-dose neck/chest CT using the iDose4 is an adequate first-line imaging modality for sharp esophageal FFBs before the endoscopic extraction.
