Description:

A PET (Positron Emission Tomography) scan is an imaging test that allows your doctor to check for diseases in your body. The scan uses special dye that has radioactive tracers. A PET-CT scan combines a CT scan and a PET scan. Doctors combine these tests because a CT scan and PET scan show different things. A CT scan shows detailed pictures of tissues and organs inside the body.A PET scan shows abnormal activity. So, the 2 scans together provide more information about the cancer. You usually have a PET-CT scan in the radiology department as an outpatient.

A MORE ADVANCED TAKEAWAY FOR YOUR HEALTH

FirstWhat is PET SCAN ??!!
  • Short description
  • A PET (Positron Emission Tomography) scan is an
    imaging test that allows your doctor to check for
    diseases in your body. The scan uses special dye
    that has radioactive tracers.
  • These tracers are either swallowed, inhaled, or
    injected into a vein in your arm depending on
    what part of the body is being examined.
  • our organs and tissues then absorb the tracer.
    The tracers help your doctor to see how well your
    organs and tissues are working.
  • The PET scan can measure blood flow, oxygen use,
    how your body uses sugar, and much more.
  • PET scan are most commonly used to detect -
    CANCER, HEART PROBLEMS, BRAIN DISORDERS including
    CNS ltCentral Nervous Systemgt.

What PET Scanner Detects?!
  • PET SCANNER CAN
  • Measure vital functions such as blood flow,
    oxygen use, and glucose (blood sugar) metabolism
    to help doctors identify organs and tissues that
    are not working properly.
  • Detect tumor cells for initial cancer staging
    (classification)
  • Evaluate how well a patient's treatment plan is
    working, allowing the care to be adjusted, if
    necessary.

How is a PET scan different from a CT or MRI
scan?
  • One of the main differences between PET scans and
    imaging tests like a CT MRI is that the PET
    scan reveals metabolic changes in an organ or
    tissue earlier at the cellular level.
  • This is important and unique because diseases
    often begin with functional changes in the cells.
  • A PET scan can often detect these very early
    changes, whereas a CT or MRI detect changes a
    little later.

PET-CT SCAN??!!
  • A PET-CT scan combines a CT scan and a PET scan
  • It gives detailed information about your cancer.
  • The CT scan takes a series of x-rays from all
    around your body.
  • The PET scan uses a mildly radioactive drug to
    show up areas of your body where cells are more
    active than normal.
  • You usually have a PET-CT scan in the radiology
    department as an outpatient.
  • A radiographer operates the scanner. It usually
    takes between 30 and 60 minutes.

6
Why you might have it??!!
  • PET-CT scans are for many types of cancer.
    They are generally thought to be more accurate in
    diagnosing cancer than PET scans alone.
  • PET-CT scans can help to
  • Diagnose cancer
  • stage a cancer, so doctors know whether it has
    spread, decide whether you can have surgery to
    remove your cancer
  • find the place in the body where you cancer first
    started to grow (primary cancer)
  • After you have had treatment for cancer, a scan
    may show an area that looks like there might
    still be some cancer left. This might not be
    cancer but scar tissue left over from the cancer
    killed off by your treatment.

7
How does a PET-CT scan work?
  • A PET scan creates pictures of organs and tissues
    in the body.
  • First, a technician gives you an injection of a
    small amount of a radioactive substance.
  • Your organs and tissues pick up this substance
  • Cancer cells pick up a lot, because they tend to
    use more energy than healthy cells.
  • Then a scan shows where the radioactive substance
    is in your body

8
Getting ready for a PET-CT scan
  • When you schedule a PET-CT scan-
  • you might need to drink only clear liquids after
    midnight the night before the scan.
  • You might need to stop eating and drinking at
    least 4 hours before the scan
  • Tell your doctor or nurse about all the
    medications you take
  • Mention any allergies and other medical
    conditions
  • If you are breastfeeding or might be pregnant,
    tell your doctor (A PET scan could be dangerous
    for the baby).
  • You need to stay still and holding breathe at
    times during scan.
  • If your PET-CT is for radiation treatment
    planning, you might wear a mask or cast during
    the scan

9
Having the PET-CT scan
  • The couch slowly slides backwards and forwards
    through the scanner.
  • The machine takes pictures as you move through
    it.
  • The scan is painless but can be uncomfortable
    because you have to stay still.
  • Tell your radiographer if youre getting stiff
    and need to move
  • Its not particularly noisy but youll hear a
    constant background noise.
  • When its over, your radiographer will come back
    into the room and lower the couch so you can get
    up.

After having scan -
  • Your radiographer removes the tube from your arm
    before you go home
  • You can then eat and drink normally. Someone will
    need to take you home if youve had medicine to
    help you relax
  • The radiotracer gives off very small levels of
    radiation that go away very quickly
  • But for the rest of the day you shouldnt have
    close contact with pregnant women, babies or
    young children

11
Possible risks??!!
  • A PET-CT scan is a safe test for most people. But
    like all medical tests it has some risks.
  • Your doctor and radiographer make sure the
    benefits of having the test outweigh these risks
  • Pregnant women should only have the scan in an
    emergency. Theres a risk that the radiation
    could harm the baby.
  • If you are breastfeeding, let the department know
    a few days before your appointment
  • He will let you know if you need to stop
    breastfeeding for a length of time after having
    the radioactive drug. The radiation in the
    radioactive tracer is very small. Drinking plenty
    of fluids after your scan will help to flush the
    drug out of your system.

How is a PET-CT scan different than a CT scan?
