What does MRI stand for?

The role of MRI in detecting and monitoring trauma and injuries is to:

• provide detailed images of soft tissues

• measure bone density

• assess blood sugar levels

• monitor heart rate

MRI generates detailed images of the inside of the body by:

• using X-rays to capture images of bones and tissues

• employing magnetic fields and radio waves to create detailed images of organs and tissues

• utilizing sound waves to produce images of internal organs

• applying radioactive tracers to highlight areas of interest

Fill in the blank: MRI uses strong magnetic fields and ______ to generate detailed images of the inside of the body.

• radio waves

• ultrasound

• X-rays

• infrared waves

Which of the following is NOT an application of MRI in trauma and injury?

• A) Soft tissue injuries

• B) Brain and spinal cord trauma

• C) Internal organ injuries

• D) Treating infections

The role of radio waves in MRI is to:

• create images by detecting radio waves emitted by the body

• align the protons in the body

• generate magnetic fields

• excite the protons in the body to produce signals

Fill in the blank: MRI is particularly useful for ______.

• Soft tissue injuries, brain and spinal cord trauma, internal organ injuries, bone fractures and stress injuries

• Diagnosing common cold

• Treating headaches

• Curing infections

What is one advantage of MRI over CT scans or X-rays?

• Radiation exposure

• Excellent soft tissue contrast

• Limited imaging planes
