Variation in radiographic protocols in paediatric interventional cardiology

Area of Science:

• Medical Imaging
• Paediatric Cardiology
• Radiography

Background:

• Interventional cardiology (IC) procedures in children are crucial for diagnosing and treating complex cardiac conditions.
• Standardized radiographic protocols are essential for optimizing image quality and minimizing radiation exposure in paediatric patients.

Purpose of the Study:

• To determine current radiographic protocols used in paediatric interventional cardiology (IC) across the UK and Ireland.
• To identify variations in imaging parameters and techniques employed in paediatric IC departments.
• To assess whether a standardized approach to paediatric IC exists.

Main Methods:

• A survey questionnaire was distributed to all hospitals performing paediatric IC in the UK and Ireland.
• Information gathered included imaging parameters, protocols, and types of clinical examinations performed.
• Ethical and research governance approval was obtained prior to data collection.

Main Results:

• A response rate of 79% was achieved, indicating significant engagement from clinical departments.
• A wide variation in radiographic techniques was observed among participating hospitals.
• Key differences were noted in the use of anti-scatter grids, beam filtration, digital acquisition frame rates, and equipment-specific programming.

Conclusions:

• There is no single, standardized radiographic protocol for paediatric interventional cardiology in the UK and Ireland.
• Local protocols dictate practice, leading to considerable heterogeneity in imaging techniques.
• This variation likely contributes to differences in radiation doses administered to paediatric patients during IC procedures.
