XI. Other Imaging Modalities

Question 1

Radiography

Answer 1

Uses X-ray beams to create static images of the body.
Best for imaging bones and detecting fractures.

Question 2

Computed Tomography (CT)

Answer 2

Uses multiple X-ray projections to create cross-sectional images.
Provides high-resolution images of soft tissues and bones.

Question 3

Magnetic Resonance Imaging (MRI)

Answer 3

Uses strong magnetic fields and radio waves to create detailed images.
Excellent for imaging soft tissues like the brain, muscles, and ligaments.

Question 4

Mammography

Answer 4

Uses low-dose X-rays to examine breast tissue.
Essential for early detection of breast cancer.

Question 5

Ultrasound (Sonography)

Answer 5

Uses high-frequency sound waves to create images.
Commonly used for pregnancy monitoring and organ imaging.

Question 6

Nuclear Medicine

Answer 6

Uses radioactive tracers to examine organ function.
Includes PET and SPECT scans for metabolic imaging.

Question 7

Hybrid Imaging (Fusion Imaging)

Answer 7

Combines multiple imaging techniques for enhanced diagnosis.
Examples include PET/CT and SPECT/CT.

Question 8

Molecular Imaging

Answer 8

Uses targeted tracers to visualize biological processes at a cellular level.
