  3. Cardiac catheterization

  4. Magnetic resonance imaging (MRI)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cardiac catheterization is an invasive procedure in which a thin tube is inserted into an artery or vein and guided to the heart. This allows doctors to visualize the coronary arteries and identify any blockages or narrowing.

  1. Image Processing

  2. Computer Vision

  3. Deep Learning

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

These techniques are used to analyze medical images, such as X-rays, CT scans, and MRI scans, to identify abnormalities that may be indicative of a disease.

Multiple choice

Which medical imaging technique allows doctors to visualize internal organs and structures in real-time, aiding in diagnosis and treatment?

  1. X-ray

  2. Ultrasound

  3. Magnetic Resonance Imaging (MRI)

  4. Computed Tomography (CT) Scan
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to create real-time images of internal organs and structures. It is commonly used for prenatal imaging, abdominal examinations, and diagnosing various medical conditions.
