Which imaging technique uses magnetic fields and radio waves to create detailed images of the internal structures of the body?

MRI

Explanation

MRI utilizes magnetic fields and radio waves for detailed internal body imaging.

What does CT stand for in the context of medical imaging?

Computed Tomography

Explanation

CT stands for Computed Tomography in medical imaging.

What is the role of a contrast agent in medical imaging?

To enhance visibility of certain structures or tissues

Explanation

Contrast agents enhance the visibility of specific structures or tissues in medical imaging.

Which imaging technique is based on the principles of sound waves bouncing off tissues and returning to the transducer to create an image?

Ultrasound

Explanation

Ultrasound imaging is based on sound waves bouncing off tissues and creating an image.

In nuclear medicine imaging, what isotope is commonly used for bone scans?

Technetium-99m

Explanation

Technetium-99m is commonly used for bone scans in nuclear medicine imaging.

Which imaging technique is often used to visualize blood vessels and detect blockages or abnormalities?

Angiography

Explanation

Angiography is employed to visualize blood vessels and detect blockages or abnormalities.

Which imaging technique is commonly used for studying brain function and activity by measuring blood flow and oxygen levels?

Functional Magnetic Resonance Imaging (fMRI)

Explanation

fMRI is used for studying brain function by measuring blood flow and oxygen levels.

In X-ray imaging, what is the term for the shadow cast by dense structures, such as bones, on the X-ray detector?

Contrast

Explanation

The shadow cast by dense structures on the X-ray detector is termed 'Contrast' in X-ray imaging.

Which imaging technique is particularly useful for visualizing soft tissues, such as muscles and tendons?

MRI

Explanation

MRI is particularly useful for visualizing soft tissues like muscles and tendons.

#10

Which imaging technique is commonly used to assess blood flow and detect vascular abnormalities in the heart?

Echocardiography

Explanation

Echocardiography is used to assess blood flow and detect vascular abnormalities in the heart.

#11

In PET imaging, what is the most commonly used radiotracer for assessing glucose metabolism in tissues?

F-18 FDG

Explanation

F-18 FDG is the most commonly used radiotracer in PET imaging for assessing glucose metabolism.

#12

What is the principle behind ultrasound imaging?

Echolocation using sound waves

Explanation

Ultrasound imaging is based on echolocation using sound waves.

#13

What is the primary advantage of using 3D mammography (tomosynthesis) over traditional 2D mammography?

Improved detection of breast cancers

Explanation

3D mammography offers improved detection of breast cancers compared to traditional 2D mammography.

#14

What is the primary advantage of using a gamma camera in nuclear medicine imaging?

Simultaneous imaging of multiple tracers

Explanation

Gamma cameras in nuclear medicine allow simultaneous imaging of multiple tracers.

#15

What is the primary advantage of using intravascular ultrasound (IVUS) in cardiovascular imaging?

Assessing plaque morphology and vessel wall characteristics

Explanation

IVUS in cardiovascular imaging allows assessing plaque morphology and vessel wall characteristics.

#16

What is the primary advantage of using dual-energy X-ray absorptiometry (DEXA) in bone density measurements?

Low radiation dose

Explanation

DEXA in bone density measurements offers the primary advantage of a low radiation dose.

#17

What is the primary advantage of using fluoroscopy in medical imaging?

Real-time dynamic imaging

Explanation

Fluoroscopy offers the primary advantage of real-time dynamic imaging in medical imaging.

#18

What is the primary advantage of using SPECT (Single Photon Emission Computed Tomography) in nuclear medicine imaging?

Visualization of metabolic activity

Explanation

SPECT in nuclear medicine imaging provides the primary advantage of visualizing metabolic activity.
