  1. Fluoroscopy

  2. Magnetic Resonance Imaging (MRI)

  3. Computed Tomography (CT)

  4. Ultrasound
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Computed Tomography (CT) is often used for guiding biopsies and tumor ablations due to its ability to provide detailed cross-sectional images and its accuracy in localizing lesions.

Multiple choice

  1. Guiding vascular interventions

  2. Visualizing blood flow patterns

  3. Assessing organ function

  4. Detecting tumors and masses
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ultrasound is commonly used in Interventional Radiology to guide vascular interventions such as angioplasty and stent placement due to its ability to provide real-time images of blood vessels.

Multiple choice

Which imaging technique is best suited for visualizing soft tissue structures and blood flow?

  1. Fluoroscopy

  2. Magnetic Resonance Imaging (MRI)

  3. Computed Tomography (CT)

  4. Ultrasound
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Magnetic Resonance Imaging (MRI) excels in visualizing soft tissue structures and blood flow due to its high contrast resolution and ability to generate detailed cross-sectional images.

Multiple choice
