Questions: Question 17 1 pts The distinguishing difference between CT and MRI is: cross-sectional images digital imaging magnetic field versus radiation use of contrast Question 18 1 pts Qualifications for the radiologic science program director, faculty, clinical coordinator, and clinical instructor are addressed by: ARRT ASRT JRCERT The Joint Commission

Question 17: The answer is the third one (C): magnetic field versus radiation.

Explanation:

• Cross-sectional images: Both CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) produce cross-sectional images of the body, so this is not a distinguishing difference.
• Digital imaging: Both modalities use digital imaging technology, so this is also not a distinguishing difference.
• Magnetic field versus radiation: This is the key difference. CT uses X-rays (a form of ionizing radiation) to create images, while MRI uses strong magnetic fields and radio waves (non-ionizing radiation) to generate images.
• Use of contrast: Both CT and MRI can use contrast agents to enhance image quality, so this is not a distinguishing difference.

Question 18: The answer is the third one (C): JRCERT.

Explanation:

• ARRT (American Registry of Radiologic Technologists): This organization certifies and registers radiologic technologists but does not specifically address qualifications for program directors, faculty, clinical coordinators, and clinical instructors.
• ASRT (American Society of Radiologic Technologists): This organization provides continuing education and professional development for radiologic technologists but does not set qualifications for educational program roles.
• JRCERT (Joint Review Committee on Education in Radiologic Technology): This organization accredits educational programs in radiologic technology and sets standards for the qualifications of program directors, faculty, clinical coordinators, and clinical instructors.
• The Joint Commission: This organization accredits healthcare organizations and programs but does not specifically address qualifications for educational program roles in radiologic science.

Summary:

• The distinguishing difference between CT and MRI is the use of magnetic field versus radiation.
• Qualifications for the radiologic science program director, faculty, clinical coordinator, and clinical instructor are addressed by JRCERT.
