    Course Description

    Until recently, 3 Tesla magnetic resonance imaging (3T MRI) was only used in research applications. However, as MRI technology evolves, 3T MRI studies (as opposed to 1.5T) are increasingly common in the clinical setting. The higher field strength of 3T MRI results in an increase in signal-to-noise ratio, spatial resolution, and speed, all of which may provide substantial benefits. However, radiologists familiar with 3T MRI have cited several limitations to the increased field strength, such as a greater amount of noise, imaging contrast issues, and safety concerns. This article will discuss the present challenges, benefits, and limitations of 3T MRI in the clinical setting in specific clinical applications, including imaging studies of the brain, spine, chest.

    Learning Objectives

    After reading this article, participants should be able to:

    • Describe the history of magnetic resonance imaging (MRI) in clinical applications.
    • Identify radiologic techniques used to improve traditional MRI image quality.
    • Identify radiologic techniques used to overcome the limitations of 3 Tesla (3T) MRI.
    • Explain the benefits and drawbacks of 3T MRI.
    • Discuss special considerations when using 3T MRI in specific clinical applications, including full body imaging, neuroimaging, musculoskeletal imaging, and breast imaging.

  • CE Information:

    In order to receive CE credit, you must first complete the activity content. When completed, go to the "CE Test" link to access the post-test.

    Submit the completed answers to determine if you have passed the post-test assessment. You must obtain a score of 75% to receive the CE credit. You will have no more than 3 attempts to successfully complete the post-test.

    Participants successfully completing the activity content and passing the post-test will receive 1.0 ARRT Category A credits.

    Approved by the American Society of Radiologic Technologists for ARRT Category A credit.

    This activity may be available in multiple formats or from different sponsors. ARRT does not allow CE activities such as Internet courses, home study programs, or directed readings to be repeated for CE credit in the same or any subsequent biennium.

ABSTRACT

Until recently, 3 Tesla magnetic resonance imaging (3T MRI) was only used in research applications. However, as MRI technology evolves, 3T MRI studies (as opposed to 1.5T) are increasingly common in the clinical setting. The higher field strength of 3T MRI results in an increase in signal-to-noise ratio, spatial resolution, and speed, all of which may provide substantial benefits. However, radiologists familiar with 3T MRI have cited several limitations to the increased field strength, such as a greater amount of noise, imaging contrast issues, and safety concerns. This article will discuss the present challenges, benefits, and limitations of 3T MRI in the clinical setting in specific clinical applications, including imaging studies of the brain, spine, chest, abdomen, pelvis, extremities, cardiac system, vascular system, and breast.
