Gamma Camera

A Gamma Camera is an imaging technique device that produces functional scans of the brain, lungs, thyroid, liver, skeleton, gallbladder and kidneys.This nuclear medicine imaging uses small amounts of radioactive material to diagnose, evaluate or treat a variety of diseases. Many varieties of cancers, heart disease, gastrointestinal, endocrine or neurological disorders and other abnormalities can be diagnosed through this. Since nuclear medicine exams can pinpoint molecular activity, this technique is very useful in identifying a disease in its earliest stages. It can also indicate if a patient is responding to the prescribed treatment.Except in the case of intravenous injections, most nuclear medicine procedures are minimally invasive and painless. Significant discomfort or side effects are rarely detected.

So what does it feel like? Well, when the radiotracer is given intravenously, you feel a slight pin prick. That’s because the needle is inserted into your vein for the intravenous line. You may feel a cold sensation moving up your arm when the radiotracer is injected. Otherwise, there are no other side effects generally.

How about when it is swallowed? You’ll be glad to hear that the radiotracer has little or no taste. If you inhale it, you should feel no differently than when breathing the air around you or holding your breath.

In some procedures, a catheter may be placed into your bladder. This may cause temporary discomfort.What’s important is, that you remain still during the exam. Nuclear imaging itself causes no pain. However, the process of being still in one particular position during imaging may make you restless.

Unless your doctor tells you otherwise, you may resume your normal activities after your exam. Our technologist, nurse or doctor will provide you with any necessary special instructions before you leave.

Benefits vs Risks


  • 1. Unique Information: Including details on the function and anatomy of body structures that are often difficult to get, using other imaging procedures.
  • 2. Useful Diagnostic Treatment: Provides the most useful diagnostic or treatment information for many diseases.
  • 3. Affordable: yields more precise information than exploratory surgery.
  • 4. Potential to identify disease earliest stages: Often, before symptoms occur or before other tests detect abnormalities.
  • 5. Can eliminate need for surgical biopsy: By detecting whether lesions are benign or malignant, PET scans may eliminate the need for surgical biopsy or identify the best biopsy location.
  • 6. Provide additional information: for radiation therapy planning.


  • 1. Involves low radiation exposure: Since only a small dose of radiotracer is used, nuclear medicine exams have a relatively low radiation exposure which is acceptable for diagnostic exams. When you compare it with the potential benefits, the risk is very low. Moreover, you must know that nuclear medicine diagnostic procedures have been used for over fifty years, and there are no known long-term adverse effects from such low-dose exposure. Also be assured that treatment risks are always weighed against the potential benefits, for nuclear medicine therapeutic procedures. Our doctors will inform you of all significant risks prior to the treatment and give you an opportunity to ask questions.
  • 2. Nuclear medicine diagnostic procedures have been used for more than five decades, and there are no known long-term adverse effects from such low-dose exposure.
  • 3. Treatment risks are always weighed against the potential benefits for nuclear medicine therapeutic procedures. Your doctor will inform you of all significant risks prior to the treatment and give you an opportunity to ask questions.
  • 4. Mild Allergic reactions: These are extremely rare and usually mild. Do tell the nuclear medicine personnel of any allergies you may have or other problems that may have occurred during a previous nuclear medicine exam.
  • 5. Slight pain and redness: May happen, which will rapidly resolve.

Points to note:

  • Lactating or breastfeeding women should inform their doctor and radiology technologist.
  • Precious jewellery and other metallic accessories must be removed, prior to the exam, as they may interfere with the procedure.
  • If you are taking any medications (including vitamins and herbal supplements), you must inform your doctor or technologist before the exam is conducted. Also list any allergies, recent illnesses and other medical conditions.
  • It is advised that you drink plenty of water to help flush the radioactive material out of your body.
