“…Operational modes are programs provided with interventional cardiology equipment, defining various aspects of irradiation, and are determined by each manufacturer. Typically, interventional cardiology systems offer three fluoroscopy operational modes: low (FL), medium (FM), and high (FH) dose, along with a cine mode (CI) [5]. Properly adjusting the system in terms of dose is expected to lead to an improvement in image quality as one moves from one operational mode to the next [1].…”

“…Furthermore, their longer lifespan increases the lifetime radiogenic cancer risk [1,4]. Studies reveal 2-3 times higher cancer likelihood from radiation exposure before age 15 as compared to adults [5][6][7]. Hence, optimizing radiation doses and image quality is crucial for pediatric interventional cardiology [3,8,9].…”

“…Within this framework, the image quality metrics commonly considered are signalto-noise ratio (SNR) [1,5,[12][13][14], contrast-to-noise ratio (CNR) [9][10][11]14] and high-contrast spatial resolution (HCSR) [6,8,11,12]. These metrics can help to optimize the settings of X-ray systems for different patient sizes, ensuring comparable image quality while minimizing patient radiation doses [11].…”

Pediatric interventional cardiology procedures are essential in diagnosing and treating congenital heart disease in children; however, they raise concerns about potential radiation exposure. Managing radiation doses and assessing image quality in angiographs becomes imperative for safe and effective interventions. This systematic review aims to comprehensively analyze the current understanding of physical image quality metrics relevant for characterizing X-ray systems used in fluoroscopy-guided pediatric cardiac interventional procedures, considering the main factors reported in the literature that influence this outcome. A search in Scopus and Web of Science, using relevant keywords and inclusion/exclusion criteria, yielded 14 relevant articles published between 2000 and 2022. The physical image quality metrics reported were noise, signal-to-noise ratio, contrast, contrast-to-noise ratio, and high-contrast spatial resolution. Various factors influencing image quality were investigated, such as polymethyl methacrylate thickness (often used to simulate water equivalent tissue thickness), operation mode, anti-scatter grid presence, and tube voltage. Objective evaluations using these metrics ensured impartial assessments for main factors affecting image quality, improving the characterization of fluoroscopic X-ray systems, and aiding informed decision making to safeguard pediatric patients during procedures.
