It contains application of radioisotopes in medical field..

1. APPLICATION OF RADIO
ISOTOPES

2. • Radio isotopes are used in various fields
• Now we just concentrate on Medicine
Diagnosis
Therapy

3. DIAGNOSIS
Nuclear imaging
•
Radionuclide are combined with other
elements to form chemical compounds. They
are injected through intravenously or orally.
•
An external detector capture and form
images from the radiation.

5. • Recent development, PET – positron emission
tomography. Used in oncology.
Commonly used isotopes:
• Chromium-51: Used to label red blood cells
and quantify gastro-intestinal protein loss.
• Copper-64: Used to study genetic diseases
affecting copper metabolism, such as Wilson's
and Menke's diseases.

6. • Xenon-133 :Used for pulmonary (lung)
ventilation studies.
• Potassium-42: Used for the determination of
exchangeable potassium in coronary blood
flow.

7. • Holmium-166: Being developed for diagnosis and
treatment of liver tumours.
• Technetium-99m : Used in to image the skeleton
and heart muscle in particular, but also for brain,
thyroid, lungs (perfusion and ventilation), liver,
spleen, kidney (structure and filtration rate), gall
bladder, bone marrow, salivary and heart blood
pool, infection and numerous specialized medical
studies.

8. TREATEMENT
• Used to treat Hyperthyroidism, thyroid cancer,
blood disorder etc..
Commonly used:
• Cobalt-60: Formerly used for external beam
radiotherapy.
• Dysprosium-165: Used as an aggregated
hydroxide for synovectomy treatment of
arthritis.

9. • Erbium-169: Use for relieving arthritis pain in
synovial joints.
• Phosphorus-32 : Used in the treatment of
polycythemia vera (excess red blood cells).
Beta emitter.
• Rhenium-186: Used for pain relief in bone
cancer. Beta emitter with weak gamma for
imaging.
