Study Comparing CT Scan, Electrical Impedance Tomography, and Lung Ultrasound in Infants Up to 12 Months to Understand Lung Differences and Improve Bedside Monitoring

What this Trial Is About

Researchers are studying lung imaging techniques in infants, focusing on distinguishing collapsed from overinflated lung areas. The study aims to compare different imaging methodscomputed tomography CT, electrical impedance tomography EIT, and lung ultrasound LUSto identify common and unique features among these approaches and explore the potential bedside use of EIT and LUS in infants. The study uses CT scans as a standard reference, which are part of routine care for participants. EIT and LUS are performed immediately before or after the planned CT scan using mobile devices. EIT involves placing a special belt on the infants chest to measure lung function non-invasively for about five minutes, while LUS uses ultrasound to assess lung aeration. Both EIT and LUS assessments take around 20 minutes each. Participants will have their lung images collected through CT, EIT, and LUS during a single visit. Researchers will analyze EIT data offline and compare the results from all three methods over about one year. The primary goal is to evaluate how well EIT and LUS correspond to CT scans in infants with or without lung disease, helping to develop hypotheses for using these bedside techniques in clinical care.
