Introduction to PET-CT
This course provides a clear foundation in the principles and practice of PET-CT. Across four tutorials, you’ll explore the science behind PET imaging, understand how PET-CT systems work, and gain insight into tracer behaviour and image interpretation. By the end, you’ll be equipped with the essential knowledge needed to appreciate both the strengths and limitations of PET-CT in clinical practice.
PET-CT Scans Performed 2022-2023

The course is comprised of four modules:
- Tutorial One: How Positron Emission Tomography (PET) works
- Tutorial Two: How PET-CT works
- Tutorial Three: FDG metabolism
- Tutorial Four: Physiological and artefactual spectrum
Learning Objectives
- Describe the physical processes that underlie PET imaging, and how these led to the construction of PET scanners to give quantitative data
- Discuss the evolution of PET to PET-CT imaging, how imaging is done, it’s advantages and some developments of the technology
- Discuss the evolution of FDG PET in tumour imaging, tumour metabolism, and in assessing patients with cancer
- Gain an overview of the normal spectrum of physiological FDG uptake; patient-related and technique/technology-related parameters that can affect image quality; and identifying false positive and false negative findings
Suitable for radiologists and nuclear medicine physicians who intend to train to report PET-CT.
Please note: To mark this course as complete on your Learning Dashboard and access your certificate of completion, you must finish all learning modules and submit the course evaluation.
