Pectus excavatum (PEx) is a chest wall deformity that leads to sternal depression and can impair cardiopulmonary function. CT imaging is used for surgical planning but exposes children to a significant radiation dose. Ultra-low dose CT enables PEx assessment in children with radiation exposure comparable to plain radiographs. The purpose of this study is to evaluate image quality and detection of thoracic pathology on ultra-low dose CT in children with PEx. Read More

Foreign body (FB) aspiration is a common medical emergency in children, which can be fatal. Prompt diagnosis is crucial to avoid complication. Bronchoscopy represents the gold standard for diagnosis; however, false negatives can lead to unnecessary invasive testing and exposes children to procedural risks. While lateral decubitus radiographs can assess for air trapping, this exam has low sensitivity for detecting airway foreign bodies. Thus, there is a need for a sensitive and specific diagnostic imaging test in the detection of airway FB. We developed and implemented a FB chest CT protocol that is characterized by low-dose relative to a standard chest CT and no intravenous contrast. We hypothesize that low-dose chest CT is a sensitive and specific modality for detection of airway FB in the pediatric population that may ultimately decrease the negative bronchoscopy rate.

The objective for a low dose imaging protocol was to eliminate patient risks and to reduce radiation doses. Tube placements are confirmed via imaging thereby avoiding utilization of malpositioned tubes. Reduced technical parameters lessen the absorbed skin dose. A limited field of view which includes distal espohagus and airway allows accurate assessment of feeding tube position. The new region of interest eliminates unnecessary exposure to hypersensitive organs including, thyroid and reproductive structures. This coned down view requires a lower image quality thereby allowing a lower dose approach. Read More

Esophageal foreign bodies (FBs) are common in children and can lead to serious complications if undetected. Fluoroscopic esophagram has been standard for radiolucent FBs but involves giving oral contrast and possible poor patient tolerance. Low-dose chest CT offers further advantages of a faster workflow and possibility of remote interpretation.

We hypothesized that low-dose CT is sensitive and specific for radiolucent esophageal FBs in children. We correlated these results with the gold standard, esophagogastroduodenoscopy (EGD) when available and clinical resolution when no EGD was performed. Read More
