Imaging modality quiz 2

Which of the following is an true about CT imaging?

• CT imaging is generally cheaper to get than X-ray radiographs.

• CT imaging uses electromagnetic energy to create images.

• CT imaging uses sound wave energy to create images.

• CT imaging is generally cheaper to get than magnetic resonance imaging.

Which imaging modality is the most time and cost efficient at assessing bone fractures and joint problems?

• CT imaging

• X-ray radiographs

• MR imaging

• Fluoroscopy

Which imaging technique is best suited for visualizing soft tissues like the brain and spinal cord?

• CT imaging

• MR imaging

• X-ray radiographs

• Fluoroscopy

What does the "CT" in "CT scan" stand for?

• Computed Tomography

• Contrast Tomography

• Centralized Tomography

• Cranial Tomography

Which of the following best describes how a CT scanner works?

• It uses magnets to create images of the body.

• It emits high-frequency sound waves to visualize organs.

• It uses X-rays and a computer to produce cross-sectional images.

• It employs radioactive tracers to monitor metabolic activity.

Which of the following best describes how magnetic resonance imaging (MRI) works?

• It uses magnets to create images of the body.

• It emits high-frequency sound waves to visualize organs.

• It uses X-rays and a computer to produce cross-sectional images.

• It employs radioactive tracers to monitor metabolic activity.

Which imaging technique is better to observe changes in bone density?

• CT imaging

• MR imaging

• X-ray radiographs

• MR arthrogram

When is MR imaging typically preferred over CT?

• When detailed images of soft tissues like muscles are needed.

• When assessing bone fractures.

• When assessing a patient with a pacemaker or metallic implants.

• When assessing bone density

What is the primary advantage of fluoroscopy over traditional X-ray radiographs?

• Fluoroscopy avoids X-ray beam exposure for the patient.

• Fluoroscopy produces higher-resolution images.

• Fluoroscopy is faster and more convenient for patients.

• Fluoroscopy produces real-time, continuous images.

What is the primary difference between CT and MRI in terms of the imaging process?

• CT uses magnetic fields and radio waves, while MRI uses X-rays.

• CT is non-invasive, while MRI requires the injection of a contrast agent.

• CT provides real-time images, while MRI produces static images.

• CT uses ionizing radiation, while MRI does not.
