Introduction

This curriculum identifies the cognitive base of entry-level education in the practice of magnetic resonance (MR) technology. This document represents a collaborative effort involving representatives from the American Society of Radiologic Technologists (ASRT), the Association of Educators in Imaging and Radiologic Sciences (AEIRS) and the Society for MR Radiographers & Technologists (SMRT), a Section of the International Society for Magnetic Resonance in Medicine (ISMRM).

This curriculum document establishes standardized educational guidelines for MR, including clinical and didactic components. The curriculum is suitable for all programs in this discipline, including limited fellowships, certificate programs, and college-based education programs. The curriculum recognizes that the educational components are not static but represent current practice and trends in the field. Educators are responsible for incorporating new concepts and trends in the curriculum as they occur.

The document contains an outline for an educational program, with main body areas defined by the ARRT examinations. The content is designed to assure quality patient care and the production of quality diagnostic images.

The document is divided into two content areas: core content and optional content.

  • Core content: content in this section reflects educational content the MR professional community supports as essential for preparation to enter the magnetic resonance field. Specific instructional methods were intentionally omitted to allow for programmatic prerogative as well as creativity in instructional delivery.
  • Optional content: content in this section will assist program planners wishing to enhance the curriculum with select topics of instruction intended to satisfy the mission of a given program or local employment market.

The focus of this document is on core instructional content that will be expanded with institution-specific course content to fulfill the requirements for an academic degree. This document is not intended for programs that are unable to award graduates an academic degree in compliance with the ARRT associate degree requirement.

Advances in diagnostic imaging and increasing employer expectations demand independent judgment by MR technologists. Consequently, the educational process must foster critical-thinking skills. Critical thinking is incorporated in multiple content areas, and faculty are expected to develop critical thinking opportunities throughout the curriculum. The MR curriculum is based on data relevant to today’s health care environment. The curriculum offers a foundation for lifelong learning that will serve MR technologists throughout their careers. In addition, it offers flexibility to develop a curriculum that will meet the needs of individuals preparing to perform diagnostic MRI procedures.

Clinical Practice and Patient Management

Description

Content is presented as a progression in competency levels through clinical performance objectives and competency exams. The content assumes students can access the educational materials, examination facilities, and personnel necessary to competently achieve content objectives. Objectives begin with observation of activities, after which the student assists in performing the activity. When a satisfactory degree of proficiency is apparent, the student can perform the activity under direct supervision. When both the student and instructor are satisfied with the student’s proficiency, the student performs MR imaging procedures under indirect supervision to gain experience and expertise.

Objectives

  1. Describe the code of ethics and professional behaviors.
  2. Communicate professionally with patients, staff members and the general public.
  3. Demonstrate cultural competence.
  4. Explain the role of health care team members.
  5. Demonstrate proper scheduling and sequencing of imaging procedures.
  6. Correlate requested imaging procedures with clinical history and reported physical examination findings.
  7. Assess patients (e.g., screening, monitoring, etc.).
  8. Educate patients, family members, and other health care professionals.
  9. Demonstrate charting and documentation.
  10. Apply infection control precautions to prevent disease transmission.
  11. Describe communicable disease terminology and required transmission-based precautions.
  12. Evaluate and respond to medical emergencies.
  13. Differentiate the functions of tubes, catheters, lines and infusion devices.
  14. List preprocedural considerations.

Pharmacology and Drug Administration

Description

Content provides basic concepts of pharmacology. This section covers the theory and practice of venipuncture and administration of diagnostic contrast agents and/or intravenous medications.

The appropriate delivery of patient care during these procedures is emphasized.

Considerations

Prior to introducing this educational content, students should have successfully completed patient care objectives (including CPR/BLS certification), as well as objectives related to anatomy and physiology of the circulatory and excretory systems.

Although regulations regarding the administration of contrast media and intravenous medications vary by state and institution, these skills should be included in the didactic and clinical curriculum, with demonstrated competencies, of all appropriate disciplines regardless of the state or institution where the curriculum is taught.

In states or institutions where students are permitted to perform intravenous injections, educational programs have specific ethical and legal responsibilities to the patient and the student. The student shall be assured that:

  • Legal statutes allow student MR technologists to perform this procedure.
  • Professional liability coverage is adequate.
  • Adequate supervision is provided.
  • Appropriate, structured laboratory objectives are identified.
  • Competency is verified before the student performs this task under indirect supervision.

Objectives

  1. Distinguish between nonprescription drugs, prescription drugs and controlled substances.
  2. Explain the process of reporting adverse reactions to the FDA.
  3. List the six rights of drug administration.
  4. Describe the various routes of drug administration.
  5. Identify general drug actions, uses, adverse reactions, contraindications, precautions and interactions.
  6. Discuss specific considerations of MR contrast administration.
  7. Recall current practice standards regarding contrast administration.

MR Safety

Description

The content provides information on the principles of MR safety and concepts that relate to the safety of MR equipment. Because the MR environment poses unique risks to patients and personnel, screening questionnaires (both verbal and written) must be completed by all individuals entering the MR suite. Education of patients and personnel is essential to prevent MR incidents. The ACR has developed guidelines for safe MR practices. This section also discusses handling patient- and magnet-related emergencies within the MR environment, the reporting of incidents to an MR Safety Officer, and safe administration of contrast media.

Pathology

Description

Content familiarizes students with the common pathologies found in magnetic resonance imaging and the appearance of these pathologies in various imaging protocols. Content covers a broad spectrum of commonly-imaged body systems and areas.

Objectives

  1. Recognize common pathologies identified in MR.
  2. Describe signal characteristics displayed by abnormal tissues during various pulse sequences and imaging modes in illustrating pathological processes.
  3. Explain changes in sizes and shapes of anatomical structures that can indicate pathology.
  4. Describe the effect of contrast agents on visualization of common pathologies.
