What is Bone Scan?

A bone scan helps detect problems in your bones much earlier than a regular X-ray.

What Happens During the Scan?

  • A small amount of radioactive tracer is injected into your vein.
  • It travels through your blood and gets absorbed by your bones.
  • The scan then checks how your bones absorb the tracer.

What the Scan Shows:

  • Cold spots (dark areas): Could mean poor blood flow or some cancers.
  • Hot spots (bright areas): May point to arthritis, fractures, infections, or bone tumors.

Before the Scan

No Special Prep Needed

  • You don’t need to fast or follow any strict instructions.
  • After the injection, drink plenty of water—it helps.

For Women

  • Not sure if you’re pregnant? Take a test first. If pregnant, the scan is usually not done.
  • Breastfeeding? Express and store milk in advance. You can safely feed your baby the next day.

What to Wear

  • Comfortable, loose clothes.
  • Please avoid jewelry.

What to Bring With You

  • Doctor’s note or referral for the scan.
  • Full medical file, including:
    • Medicines
    • Allergies
    • Any past treatments
  • All past scan reports, X-rays, or CDs—especially for fractures, falls, or cancer.
  • Latest blood sugar and creatinine reports (or get them done at our center).
  • One family member or friend, if needed.
  • Some light, home-cooked food for after the scan.

How Long Does It Take?

  • Total time: Around 4 to 5 hours.
  • After injection: Wait 1 to 1.5 hours for the tracer to reach your bones.
  • Scan itself: Takes about 15 to 30 minutes.

After the Scan

  • You can eat, drink, and take your regular medicines.
  • Stay for a short 30-minute observation after the scan.
  • Avoid close contact with children and pregnant women for the rest of the day.
  • The tracer leaves your body through urine and stool—usually within 10–12 hours.
  • Drink plenty of water to flush it out faster.
