Overview of Five major techniques used in brain imaging, each with its unique purpose, strengths, and limitations:

1. X-Ray

Use: Primarily for imaging bones; not ideal for soft tissue like the brain.

Fact: X-rays pass through soft tissue but are absorbed by denser structures like bone, making them suitable for detecting skull fractures.

Limitation: Cannot show brain structures or abnormalities in detail.

---

2. CT (Computed Tomography) Scan

Use: Cross-sectional images of the brain using X-ray technology.

Fact: Good for detecting bleeding, tumors, and skull fractures.

Limitation: Less detail on soft tissues compared to MRI.

---

3. MRI (Magnetic Resonance Imaging)

Use: Provides detailed images of brain soft tissues using magnetic fields and radio waves.

Fact: Excellent for detecting tumors, brain injuries, developmental anomalies, and multiple sclerosis.

Limitation: More expensive and time-consuming than CT.

---

4. MRA (Magnetic Resonance Angiography)

Use: Visualizes blood vessels in the brain.

Fact: Often used to detect aneurysms, blockages, or vascular malformations.

Limitation: Requires specialized equipment and often a contrast agent.

---

5. PET Scan (Positron Emission Tomography)

Use: Assesses brain metabolism and activity.

Fact: Commonly used in Alzheimer's research, cancer detection, and epilepsy diagnosis.

Limitation: Involves radioactive tracers and is less spatially detailed than MRI.
