Insights into the Global Practice of Paediatric Renal Scintigraphy Studies.

Congenital abnormalities of the kidney and urinary tract are amongst the most common in children, often requiring nuclear medicine imaging for diagnosis and treatment planning. Efforts to harmonise paediatric renal scintigraphy have gained momentum, notably through unified guidelines published by the Society of Nuclear Medicine and Molecular Imaging (SNNMI) and the European Association of Nuclear Medicine (EANM). However, despite these guidelines, significant variation in clinical practice persists. Advances in imaging technology have also influenced protocols, with some institutions now incorporating single photon emission computed tomography (SPECT) studies when performing cortical scintigraphy. To assess the current practices, the International Atomic Energy Agency (IAEA) conducted a global survey, revealing substantial variability and gaps in the performance and interpretation of renal studies within countries and globally. This underscores the urgent need for standardization and quality improvement across institutions. The IAEA is uniquely positioned to support the global nuclear medicine community through targeted educational and capacity building initiatives.
