This course aims to equip students with a comprehensive understanding of Magnetic Resonance Imaging (MRI) sequences commonly used in clinical and research settings. Students will gain an in-depth understanding of the building blocks of MRI sequences, including radiofrequency (RF) pulses, magnetic field gradients, spatial encoding methods, and signal sampling. They will learn their characteristics and manipulation methods and how to combine them to form different sequences that produce images with various contrast weightings, such as proton density, T1-, T2, T2* and other contrasts.
Starting from the basic gradient-echo and spin-echo sequences, students will explore the composition and parameters of various sequences and how to vary them to achieve different contrasts. More advanced and emerging sequences will also be explored, enabling students to confidently manipulate scanner parameters and generate desired MRI contrast.
MR images are prone to artefacts from various sources, and identifying them is essential for MRI researchers and technicians. This course will introduce the different types of static and dynamic artefacts that commonly occur on MR images, explain their causes and the methods to eliminate or reduce them.
The skills and knowledge attained in this course will prepare students of the program for later courses in advanced applications of MRI and practical operation of MRI scanners within the clinical environment.
This foundation course is compulsory within the post-graduate Master of Magnetic ResonanceﾠTechnology.ﾠ It will provide the background knowledge that is essential to understand the material presented in later courses and provides an introduction to practical MRI pulse sequence design and construction.ﾠ Theﾠapplication of these principles is describedﾠto analyse and understand the origin of signal and its contrast weighting in a number of sequences that areﾠimportant in clinical diagnostic imaging and in research.

Task description
Non-invigilated online exam (during Exam Period). These exams are centrally controlled and run using a separate Blackboard site. You will be advised of the date and time in which to complete the examination once the examination timetable has been determined. Note that late penalties will be strictly applied as per university policy.
The examination will be centrally timetabled and in the form of a Blackboard Test (Part A) in combination with Blackboard Asssignment (Part B). The exam should be completed within a 120 minutes duration with a 10-minute perusal time - there is also a 15-minute upload allowance. The exam will be available and open during the Examinations Period for 130 minutes (+ 15 minutes submission) starting at the time specified in the student's personal examination timetable (to be announced prior to week 13 of semester). Note that there will be a 15 minutes submission period in total so the students need to complete both parts of the exam within the 130 minutes + 15 minutes submission starting at the time specified in the student's personal examination timetable. The exam will not auto-submit - students need to monitor the time they take on the exam. Students need to complete the exam within the allocated time, any exams submitted late will have a late penalty applied. If the exam is commenced after the specified time, the end for the examination does not change. There will be no requirement for identity certification.
Structure of exam
The aim of the exam is to examine what you understand about the application of MR theory to the MRI experiment, the origin of contrast generated by clinically relevant sequences and the origin of image artefacts. The exam will be divided into two parts. Part A will mostly consist of True/False and Multiple Choice questions in the form of an online Blackboard quiz and should be answered and submitted online. Part B will be in the form of short answer type questions which may include the requirement for hand-written sketches and calcula

Applications for Extensions to Assessment Due Dates
Extension requests are submitted online via my.UQ – applying for an extension. Extension requests received in any other way will not be approved. Additional details associated with extension requests, including acceptable and unacceptable reasons, may be found at my.UQ.
Please note:
- Requests for an extension to an assessment due date must be submitted through your my.UQ portal and you must provide documentation of your circumstances, as soon as it becomes evident that an extension is needed. Your application must be submitted on or before the assessment item's due date and time.
- Applications for extension can take time to be processed so you should continue to work on your assessment item while awaiting a decision. We recommend that you submit any completed work by the due date, and this will be marked if your application is not approved. Should your application be approved, then you will be able to resubmit by the agreed revised due date.
- If an extension is approved, you will be notified via your my.UQ portal and the new date and time for submission provided. It is important that you check the revised date as it may differ from the date that you requested.
- If the basis of the application is a medical condition, applications should be accompanied by a medical certificate dated prior to the assignment due date. If you are unable to provide documentation to support your application by the due date and time you must still submit your application on time and attach a written statement (Word document) outlining why you cannot provide the documentation. You must then upload the documentation to the portal within 24 hours.
- If an extension is being sought on the basis of exceptional circumstances, it must be accompanied by supporting documentation (eg. Statutory declaration).
- For extensions based on a SAP you may be granted a maximum of 7 days (if no earlier maximum date applies). See the Extension or Deferral availability section of each assessment for details. Your SAP is all that is required as documentation to support your application. However, additional extension requests for the assessment item will require the submission of additional supporting documentation e.g., a medical certificate. All extension requests must be received by the assessment due date and time.
- Students may be asked to submit evidence of work completed to date. Lack of adequate progress on your assessment item may result in an extension being denied.
- If you have been ill or unable to attend class for more than 14 days, you are advised to carefully consider whether you are capable of successfully completing your courses this semester. You might be eligible to withdraw without academic penalty - seek advice from the Faculty that administers your program.
- There are no provisions for exemption from an assessment item within UQ rules. If you are unable to submit an assessment piece then, under special circumstances, you may be granted an exemption, but may be required to submit alternative assessment to ensure all learning outcomes are met.
Applications to defer an exam
In certain circumstances you can apply to take a deferred examination for in-semester and end-of-semester exams. You'll need to demonstrate through supporting documentation how unavoidable circumstances prevented you from sitting your exam. If you can’t, you can apply for a one-off discretionary deferred exam.
Deferred Exam requests are submitted online via mySi-net. Requests received in any other way will not be approved. Additional details associated with deferred examinations, including acceptable and unacceptable reasons may be found at my.UQ.
Please note:
- Applications can be submitted no later than 5 calendar days after the date of the original exam.
- There are no provisions to defer a deferred exam. You need to be available to sit your deferred examination.
- Your deferred examination request(s) must have a status of "submitted" in mySI-net to be assessed.
- All applications for deferred in-semester examinations are assessed by the relevant school. Applications for deferred end-of-semester examinations are assessed by the Academic Services Division.
- You’ll receive an email to your student email account when the status of your application is updated.
- If you have a medical condition, mental health condition or disability and require alternative arrangements for your deferred exam you’ll need to complete the online alternative exam arrangements through my.UQ. This is in addition to your deferred examinations request. You need to submit this request on the same day as your request for a deferred exam or supplementary assessment. Contact Student Services if you need assistance completing your alternative exam arrangements request.
