Exploring Brain Imaging Techniques

Which MRI technique is commonly used to visualize brain structures with high detail?

• T1-weighted MRI

• CT scan

• PET scan

• EEG

What is a typical use of a CT scan in emergency medicine?

• Monitoring brain activity

• Detecting bone fractures

• Measuring metabolic processes

• Recording electrical activity

Which of the following is a primary application of PET scans?

• Evaluating glucose metabolism in tissues

• Measuring electrical activity in the brain

• Detecting structural changes in the brain

• Assessing bone density

Functional MRI (fMRI) is primarily used to study what aspect of the brain?

• Structural abnormalities

• Blood oxygen level changes

• Electrical impulses

• Bone density

What does EEG primarily measure?

• Blood flow in the brain

• Electrical activity along the scalp

• Metabolic activity in tissues

• Structural changes in the brain

SPECT imaging is often used to evaluate which of the following?

• Electrical activity in the brain

• Blood flow and activity in the brain

• Bone structure

• Soft tissue contrast

Which MRI technique is best for visualizing soft tissue contrast?

• T2-weighted MRI

• CT scan

• PET scan

• EEG

In what situation is a CT scan preferred over an MRI?

• When assessing soft tissue injuries

• When evaluating acute head trauma

• When measuring brain activity

• When analyzing metabolic processes

What is a key advantage of PET scans in medical imaging?

• High spatial resolution

• Ability to measure metabolic activity

• Low radiation exposure

• Real-time imaging of electrical activity

Which of the following is a limitation of fMRI?

• It cannot measure brain activity.

• It has low spatial resolution.

• It is sensitive to motion artifacts.

• It uses ionizing radiation.
