How scientists look inside your brain — and each method has different capabilities and limitations

1️⃣ X-ray
🔍 Great for bones, not brain tissue. Shows fractures, but can’t show details of the brain.

2️⃣ CT scan
📸 Creates cross-sectional images of the brain using X-rays. Great for seeing bleeding, tumors, and fractures — but less detailed than MRI.

3️⃣ MRI
Magnetic field + radio waves = highly detailed images of soft tissue. Ideal for tumors, injuries, and multiple sclerosis (MS). Cons? Cost and time consuming.

4️⃣ MRA
MRI of blood vessels. Detects aneurysms, blockages, and structural abnormalities. Often requires contrast dye.

5️⃣ PET scan
Images brain activity and metabolism. Used in Alzheimer's, cancer, and epilepsy research — but requires radioactive tracers.

From seeing fractures to mapping brain activity, each scan tells a different part of your brain's story.
