Performing chest computed tomography on pediatric patients on extracorporeal membrane oxygenation (ECMO): a stepwise...

Area of Science:

• Medical Imaging
• Pediatric Critical Care
• Cardiopulmonary Support

Background:

• Extracorporeal membrane oxygenation (ECMO) is a life-support technique for critically ill pediatric patients with cardiopulmonary failure.
• Chest computed tomography (CT) is frequently required for managing these complex patients.
• Performing CT in ECMO patients presents unique challenges and safety considerations.

Purpose of the Study:

• To review the principles of pediatric ECMO relevant to imaging.
• To outline a stepwise approach for performing safe and effective chest CT examinations in pediatric ECMO patients.
• To highlight essential considerations for contrast administration and image acquisition timing.

Main Methods:

• Review of ECMO circuit basics, including cannula types and typical locations.
• Discussion of contrast media injection techniques and timing strategies for optimal image quality.
• Emphasis on safety protocols and precautions specific to pediatric ECMO patients undergoing CT.

Main Results:

• Chest CT can be performed safely in pediatric patients receiving ECMO.
• High-quality diagnostic images can be obtained to guide clinical management.
• Understanding ECMO specifics is crucial for successful CT examination.

Conclusions:

• Chest CT is a valuable tool for pediatric patients on ECMO.
• Radiologists must be knowledgeable about ECMO to ensure patient safety and diagnostic accuracy.
• A systematic approach optimizes the performance and utility of CT in this population.
