Did you know? Radiology shows anatomy while Nuclear Medicine reveals function.
Together, they make modern medicine more powerful.

Nuclear Medicine vs Radiology – What’s the Difference?

🩻 Radiology (X-ray, CT, MRI):
• Provides structural/anatomical images
• Shows what the body looks like (size, shape, density)
• Example: CT chest shows a lung mass

☢️ Nuclear Medicine (SPECT, PET, Theranostics):
• Provides functional/metabolic images
• Shows how the body works (blood flow, metabolism, receptor expression)
• Example: FDG PET shows whether the lung mass is active cancer or not

Key Difference:
• Radiology = “What it looks like”
• Nuclear Medicine = “What it does”

Annual Radiation Doses – What’s Safe?

In radiation safety, exposure is measured in milliSieverts (mSv).
Here’s how it looks in real life:

1. Natural background radiation: ~2–3 mSv/year
2. One chest X-ray: ~0.1 mSv
3. CT scan (abdomen/pelvis): ~10 mSv
4. Typical Nuclear Medicine scan (Tc-99m bone scan, MIBI, etc.): ~4–6 mSv
5. PET/CT (FDG): ~20–25 mSv
6. Occupational dose limit (radiation workers): 20 mSv/year (averaged over 5 years, max 50 mSv in any single year)
7. Public dose limit: 1 mSv/year

Takeaway:
Most diagnostic scans expose patients to a dose well below harmful levels.
The benefit of early diagnosis & treatment far outweighs the small radiation risk.

Your first PET scan is basically a nuclear-powered selfie — except instead of a filter, it’s physics + biochemistry. 🤗

Do you know?
Nuclear medicine therapy doesn’t just treat disease — it can shrink tumors, relieve pain, and even cure certain cancers when nothing else works.

📌 Proven Results:
• Thyroid cancer → Radioiodine therapy has cured millions worldwide.
• Bone pain palliation → Radionuclide therapy relieves severe pain in advanced cancer.
• Targeted therapy (Lu-177 PSMA / DOTATATE) → Extends survival in prostate and neuroendocrine tumors.

✅ Unique Advantage: It targets diseased cells from inside the body while sparing most healthy tissue.

🔬 Nuclear medicine therapy = Precision + Power + Proven outcomes.
