Pediatric osteosarcoma and Ewing sarcoma are aggressive primary bone tumors requiring precise diagnosis and staging. 18F-FDG PET/computed tomography and PET/MRI are essential for staging, treatment monitoring, and clinical decision-making. PET/MRI provides enhanced soft-tissue contrast and reduced radiation exposure, making it well-suited for long-term surveillance in pediatric patients. Emerging molecular probes demonstrate potential for tumor-specific imaging, although their clinical utility has yet to be explored. This review aims to summarize the applications, limitations, and future directions of PET imaging in the precision diagnosis and management of pediatric osteosarcoma and Ewing sarcoma.

Imaging Studies III: Computed Tomography
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...

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...
