MRI - Reviewer 3

What is the bore of an MRI machine?

• A tube-like structure that houses components
• The outer casing of the MRI
• The cooling system of the MRI
• A part of the patient table

What are the basic components of an MRI machine?

• Magnet, Coils, Computer
• X-ray Tube, Detector, Monitor
• Gamma Camera, Photomultiplier, Display
• Cathode Ray Tube, Film, Processor

What is a major disadvantage of a closed MRI scanner?

• Can cause claustrophobia
• Lower image quality
• Limited scanning capabilities
• Uses ionizing radiation

Which type of MRI scanner is open on all four sides?

• Open MRI Scanner
• Closed MRI Scanner
• High-Field MRI Scanner
• Mobile MRI Scanner

What is a disadvantage of an open MRI scanner?

• Lower image quality
• Higher patient dose
• Increases claustrophobia
• Requires contrast for all scans

What is the primary function of the MRI magnet?

• To create a stable magnetic field
• To produce X-rays
