Question

Identify the image modality given below.

• A. Cerebral blood flow scan
• B. PET CT
• C. Sestamibi scan
• D. Full body MDCT

Answer 1

The Correct Option is B

The image modality in question is PET CT. To identify this modality, you need to recognize the unique characteristics of PET CT scans. PET, or Positron Emission Tomography, is a nuclear medicine imaging technique that produces a three-dimensional image or map of functional processes in the body. It is typically combined with CT (Computed Tomography) to provide detailed anatomical information.

Here are key features that help identify a PET CT:

• Uses a radioactive tracer, often glucose-based, that emits positrons.
• Highlights areas of high metabolic activity, which appear brighter on the scan.
• The CT component provides detailed cross-sectional images of the body's structures.
• PET CT images typically appear as colored overlaid images on a grayscale CT background, indicating metabolically active regions.

Among the given options, PET CT is the correct choice based on the described imaging characteristics.
