Summary
Long axial field-of-view (LAFOV) PET/CT scanners enhance paediatric nuclear medicine by improving image quality and reducing radiation doses. These advanced systems offer faster, more comfortable whole-body scans for children, aligning with the ALARA principle.
Area of Science:
- Nuclear Medicine
- Medical Imaging
- Paediatric Diagnostics
Background:
- Paediatric nuclear medicine faces challenges with radiation sensitivity and procedural compliance in children.
- Traditional PET/CT scanners have limitations in scan time and radiation dose, impacting young patients.
- Long axial field-of-view (LAFOV) PET/CT technology offers potential solutions to these paediatric imaging issues.
Purpose of the Study:
- To review the technical advancements of LAFOV PET/CT systems.
- To explore the expanding role and clinical advantages of LAFOV PET/CT in paediatric imaging.
- To address the opportunities and challenges associated with implementing LAFOV PET/CT in children.
Main Methods:
- Review of technical specifications and clinical applications of LAFOV PET/CT scanners.
- Analysis of benefits including enhanced sensitivity, reduced radiopharmaceutical doses, and shorter scan times.
- Discussion of whole-body imaging capabilities and impact on motion artefacts and patient comfort.
Main Results:
- LAFOV PET/CT provides superior image quality with significantly reduced radiation exposure and scan durations.
- Whole-body imaging in a single position minimizes motion artefacts, enhancing patient experience and reducing anxiety.
- The technology supports personalized imaging protocols, aligning with the ALARA principle for paediatric radiation safety.
Conclusions:
- LAFOV PET/CT represents a significant advancement in paediatric nuclear medicine, improving diagnostic capabilities.
- The technology overcomes limitations of conventional scanners, enabling safer, faster, and more comprehensive paediatric assessments.
- Despite initial costs, LAFOV PET/CT promises to transform paediatric diagnostics through enhanced imaging and patient-centered care.

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
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...

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.
