Pediatric imaging research needs to advance beyond retrospective studies. The ACR-Pediatric Imaging Research Committee identified 10 priority areas for predictive, preventive, personalized, and participatory (P4) pediatric care.
Area of Science:
- Pediatric radiology
- Medical imaging innovation
- Healthcare research
Background:
- Pediatric imaging advancements have been limited by single-center and retrospective studies.
- Previous research has not fully benefited pediatric patients.
- A need exists for significant progress in pediatric imaging.
Purpose of the Study:
- To identify high-impact research directions for pediatric imaging.
- To explore the P4 concept (predictive, preventive, personalized, and participatory) in pediatric diagnosis and intervention.
- To guide future research for quantum-leap progress in the field.
Main Methods:
- Convened the ACR-Pediatric Imaging Research (PIR) Committee.
- Gathered input from 237 members of the Society for Pediatric Radiology.
- Clustered input into 10 priority research areas.
- Analyzed needs within each priority area by experts.
Main Results:
- Identified 10 priority research areas for pediatric imaging.
- Detailed analysis of needs within each priority area.
- Focus on P4 principles for diagnosis and intervention.
Conclusions:
- Future pediatric imaging research should focus on 10 identified priority areas.
- Adopting P4 principles can revolutionize child healthcare.
- Shift focus from reactive treatment to proactive health maintenance.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Fundamental Principles of PET
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...
