Artefacts in PET-CT

This course comprises of three tutorials where we discuss the clinical problems faced as a result of artefacts seen on FDG PET-CT imaging, and we’ll also cover some of the basic technical aspects behind the artefact and discuss some practical ways to minimise them.

An artefact (or pitfall) is something which is observed in a scientific investigation or experiment that is not naturally present but occurs as a result of the investigative procedure. So it is the result of the technique used and is not a natural occurrence, but merely incidental.

PET-CT Scans Performed 2022-2023

There are three broad categories of artefacts seen on FDG PET-CT imaging. These are covered in the following learning modules.

• Tutorial One: Radiotracer-related artefacts
• Tutorial Two: Patient-related artefacts
• Tutorial Three: Instrument-related artefacts

Learning Objectives

• Identify radiotracer-related, patient-related and instrument-related artefacts
• Determine the cause of radio-tracer-, patient-, and instrument-related artefacts and how they may lead to a false diagnosis
• Discuss remedies for each category and sub-category of artefacts

Suitable for radiologists and nuclear medicine physicians who intend to train to report PET-CT.
