RAD4503 · Physical foundations of magnetic resonance imaging

Overview

This unit explores the fundamentals of magnetic resonance imaging (MRI). The physical principles will be presented and examined. The factors that determine the contrast and spatial resolution achievable in MRI are discussed. Equipment used to generate MRI images will be discussed and the student will consider the design and purpose of the major components of a clinical MR scanner. Patient and MRI staff safety issues posed by magnetic and radio frequency fields are presented, along with current issues posed by use of contrast agents.

Areas of study: Radiography and medical imaging Radiation sciences

Assessment

The Handbook lists an examination for this unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

1. Justify the physical design and operational requirements for a typical clinical MRI system
2. Explain the imaging parameters that define the contrast sensitivity in MRI
3. Evaluate the advantages and disadvantages of gradient and spin echo recovery techniques
4. Present logical arguments for use of different contrast agents in clinical practice
5. Justify the reasons for precautions that are taken in MRI to ensure staff and patient safety
6. Recognise deficiencies in images, such as reconstruction artefacts, identify the cause of such problems, and implement strategies to correct or attenuate image artefacts

Workload

On-line delivery - course designed only for post graduate students. There will be video clips and video-conferences available throughout the course to assist in directing students. Discussion forums will be initiated to further direct student outcomes.

Student experience, not official rules. Nothing here changes what the Handbook says.
