Each imaging technique operates on different principles:
- X-rays: High-energy radiation passes through the body, and the resulting images reveal various structures based on their density. - CT Scans: Multiple X-ray images are taken from different angles and combined using computer algorithms to create cross-sectional views. - MRI: A strong magnetic field aligns hydrogen atoms in the body, and radio waves disturb this alignment. The emitted signals are captured to generate images. - Ultrasound: Sound waves bounce off tissues, and the echoes are used to form images. - PET Scans: A radioactive tracer is injected into the body, and its uptake by tissues is measured to assess metabolic activity. - Mammography: Low-dose X-rays are used to examine breast tissue for abnormalities.
