{short description of image} Introduction

As the bar above indicates, this project is still very much "Under Construction". I hope you will bear with me in my efforts to bring it all together. If you have any suggestions, comments or criticisms, please offer them. I am very interested in what you have to say.

This work has been designed as a student-centered learning opportunity to provide you with guidance in learning the required knowledge and skills related to Nuclear Medicine studies of the gastrointestinal system.

Self-directed, life-long learning is an essential skill for medical technology professionals to ensure they maintain a current knowledge base and skill set. The technologists of today must be able to access and evaluate information from a variety of sources and distill the results of their research into a format that best suits their needs and learning styles.

You are invited to approach this task in any way you wish. For example:

  • you may choose to work independently to gather, assess, collate and assimilate the information,
  • you may wish to form study groups to work cooperatively toward achieving your common goal,
  • you may decide to divi out portions of the task and share the fruits of each others labour, or
  • you may choose some other course of action that best suits your ability to attain your goal.

However you choose to approach the learning experience, this document attempts to provide you with a foundation upon which to begin. You are encouraged to share and discuss your research among yourselves and to assist each other in achieving maximum benefit from this learning opportunity. Should you have any questions or concerns that you cannot solve in consultation with your colleagues, please do not hesitate to consult with your instructor.

Timetabled sessions during third semester will be used for discussion of your findings and for review of case studies.

Most of all, you are encouraged to view this activity as an opportunity to learn new things and develop new skills rather than as a chore. This approach to tasks will serve you well both now and in your future as a Nuclear Medicine Technologist. Enjoy!!!

To help you evaluate your progress in this endeavour, self assessment quizzes are provided at the end of each section.

{short description of image} Goal and Objectives

Your goal is to develop a comprehensive understanding of the application of Nuclear Medicine procedures in the diagnosis and management of gastrointestinal disorders. This includes an understanding of the following aspects relevant to each Nuclear Medicine procedure:

  • review of pathology
  • principle of the study
  • indications for the study
  • patient preparation
  • pharmacological interventions
  • radiopharmaceuticals used
  • equipment required including appropriate setup
  • procedure for performing the study including:
    • patient positioning
    • computer / gamma camera settings
    • views (if applicable)
    • drug interventions (if applicable)
    • computer analysis technique (if applicable)
  • normal versus abnormal results
  • common technical difficulties and artifacts
  • other modalities for determining the same or similar information

The objectives for this course are divided into two sets. There is a set of educational objectives which provide an overview of the learning skills to be developed plus a set of specific content objectives focusing on the required knowledge base and skill set of each subsection of the gastrointestinal system to be studied.

Gastrointestinal System Studies

A list of the gastrointestinal tract studies that will be considered in this course is provided below. Each heading is hyperlinked to additional information that is intended to help get you started. Should you find any relevant information in any format that you believe would be of particular interest to your classmates or to your tutor, you are encouraged to share it.

Also provided is an example of an outline for organizing your information; however, you are free to gather and collate the data any way you choose.

Gastrointestinal Bleeding Detection and Localization

  • Using Tc-99m Sulfur Colloid
  • Using Tc-99m Red Blood Cells

Inflammatory Bowel Disease Imaging

Ectopic Gastric Mucosa Imaging

Gastric Emptying Half-Time Determination

Gastroesophageal Reflux Imaging and Function Study

Esophageal Motility Function Study

Salivary Gland Imaging

Assignment

An assignment valued at 7.5% of your course mark for NMNU410 is required to be completed and submitted for grading. The assignment requires the completion and submission of written answers to seven questions relating to Nuclear Medicine gastrointestinal system procedures. The assignment is given out early in the term to allow you ample opportunity to research and complete it.

Students are encouraged to participate in the development, content validation and referencing of multiple choice questions for use on examinations and in self assessments. In this way you, as a student, can have content input to the evaluation process. A set of guidelines for the formulation of good quality multiple choice questions is provided.

Any student who would like to develop several multiple choice examination questions in lieu of doing the written assignment is asked to contact your tutor.
