PROGRAM: Medical Imaging
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 3
DATE OF LAST REVISION: Spring, 2021
Content provides the student with a comprehensive overview of MR imaging principles. The subjects are formatted in individual outlines and can be sequenced according to the level of knowledge desired. Topics include history of MR, nuclear MR (NMR) signal production, tissue characteristics, pulse sequencing, imaging parameters/options and image formation. Content introduces knowledge in computing and information processing. It presents computer applications in the radiologic sciences related to image capture, display, storage and distribution. Additional content is designed to provide the basic concepts of patient information and management. Medical records management, including privacy and regulatory issues, are examined. The role of the technologist is identified and discussed. In addition, this content imparts an understanding of the components, principles and operation of digital imaging systems found in MR, image data management, storage and data manipulation (post-processing). Factors that impact image acquisition, display, archiving and retrieval are discussed. Content also provides a comprehensive overview of the instrumentation associated with MR imaging. The subjects are formatted in individual outlines and can be sequenced according to level of knowledge desired. Topics include: magnetism, MR system components, MR magnets (e.g., permanent, resistive, superconducting, hybrid), radiofrequency (RF) systems, gradient systems, shim systems and system shielding.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student is expected to:
- Describe computer fundamentals, the evolution and role of healthcare informatics, digital imaging characteristics, the methods of image display (e.g., monitor, film, digital, etc.) and the procedural factors (e.g., image identification, documentation of ordered imaging procedure, artifacts and image evaluation).
- Examine the impact of regulations, laws and standards related to informatics on health care delivery.
- Explain the ethical concerns related to healthcare informatics, RIS, HIS and PACS applications as they relate to radiology.
- Evaluate decision-making strategies used in informatics and compare and contrast different informatics applications in health care.
- Apply digital imaging acquisition requirements and The Joint Commission/HIPAA standards regarding accountability and protection of patient information.
- Demonstrate imaging standard expectations (e.g., protocol and parameter selection, problem-solving, etc.) and postprocessing strategies (e.g., 3-D, MIP, Region of Interest, etc.).
- Analyze the cause and correction of image artifacts.
- Describe magnetism and magnetic properties, the three basic types of commercially available clinical magnets, citing advantages, and disadvantages of each, field strength in relation to image quality (e.g., image contrast, SNR and artifacts) and the importance of the shim system in MR imaging.
