Brain Imaging Technology Quiz

What is the primary purpose of brain imaging technology?

• To evaluate the brain

• To improve memory

• To enhance brain size

• To increase intelligence

How is brain imaging technology categorized?

• By brain size and weight

• By brain structure or brain function

• By age and gender

• By memory capacity

What is computerized tomography (CT) primarily used for?

• To measure blood pressure

• To detect brain damage

• To monitor heart rate

• To assess lung function

How do dense tissues appear on a CT scan?

• As dark areas

• As light areas

• As red areas

• As blue areas

What is a disadvantage of using CT scans?

• They are slow and not widely available

• They expose patients to radiation

• They cannot detect brain damage

• They are not useful for imaging bones

What is a benefit of CT scans?

• They are non-invasive and do not use radiation

• They are quick and widely available

• They provide real-time imaging

• They are the only method to detect heart disease

What does MRI use to generate an image?

• X-rays and sound waves

• Radio waves and magnetic field

• Ultrasound and magnetic field

• Infrared waves and electric field

What is a key advantage of MRI over CT scans?

• MRI is faster than CT

• MRI uses radiation

• MRI can distinguish very fine details

Why might MRI be contraindicated for some patients?

• It uses radiation

• It is too fast

• It is contraindicated for patients with metal implanted devices

• It is less detailed than CT

What does Functional Magnetic Resonance Imaging (fMRI) detect?
