Abstract:
This article examines the expanding role of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography with computed tomography (PET/CT) in pediatric non-oncological conditions, moving beyond its established oncologic use. It outlines radiation dosimetry principles unique to children-emphasizing the As Low as Reasonably Achievable principle, reduced tracer activity, and low-dose CT protocols-given their heightened radiosensitivity. In pediatric neurology, FDG PET/CT aids evaluation of drug-refractory epilepsy (temporal and extratemporal foci) and neuronal migration/proliferation anomalies like focal cortical dysplasia (FCD), polymicrogyria, and hemimegalencephaly.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
