Which imaging modality utilizes electromagnetic radiation to generate cross-sectional images of the body?

  1. X-ray

  2. Ultrasound

  3. Magnetic Resonance Imaging (MRI)

  4. Computed Tomography (CT)


Correct Option: D
Explanation:

Computed Tomography (CT) utilizes electromagnetic radiation in the form of X-rays to generate cross-sectional images of the body, providing detailed anatomical information.

What is the primary advantage of Magnetic Resonance Imaging (MRI) over X-ray imaging?

  1. Higher resolution images

  2. Lower radiation exposure

  3. Ability to image soft tissues

  4. Faster image acquisition


Correct Option: C
Explanation:

Magnetic Resonance Imaging (MRI) utilizes magnetic fields and radio waves to generate images, allowing for excellent visualization and differentiation of soft tissues, which are often difficult to visualize with X-ray imaging.

Which imaging modality is commonly used for real-time visualization of internal organs and structures?

  1. X-ray

  2. Ultrasound

  3. Magnetic Resonance Imaging (MRI)

  4. Computed Tomography (CT)


Correct Option: B
Explanation:

Ultrasound utilizes high-frequency sound waves to generate real-time images of internal organs and structures, making it particularly useful for dynamic studies and examinations.

What is the term for the process of converting medical images into digital data?

  1. Image acquisition

  2. Image processing

  3. Image reconstruction

  4. Image digitization


Correct Option: D
Explanation:

Image digitization refers to the process of converting analog medical images, such as X-ray films, into digital data using specialized scanners or digitizers.

Which imaging modality is commonly used for diagnosing bone fractures and detecting abnormalities in bone structure?

  1. X-ray

  2. Ultrasound

  3. Magnetic Resonance Imaging (MRI)

  4. Computed Tomography (CT)


Correct Option: A
Explanation:

X-ray imaging is commonly used for diagnosing bone fractures and detecting abnormalities in bone structure due to its ability to penetrate dense tissues and provide clear visualization of bones.

What is the primary role of a medical imaging informaticist?

  1. Developing new imaging techniques

  2. Interpreting medical images
