Myocardial Perfusion
Imaging Scan(MPI Scanning) |
Myocardial perfusion
imaging (MPI) scan or scanning is the only
widely available and validated
method of assessing myocardial
perfusion. MPI scan is the standard
clinical technique for assessing
myocardial perfusion. When MPI
scanning is used for the diagnosis
of CAD, it is not being used purely
to predict the presence of
epicardial coronary stenoses. |

Use of MPI Heart
Scanning In The Investigative
Strategies |
MPI scans
or scanning should be
the initial investigation in
patients who are unlikely to
exercise adequately. It is also
reasonable to suggest that even
patients with a high likelihood of
CAD can be considered for MPI scan
or scanning before coronary angiography. MPI
scanning can assess objectively the
extent and severity of myocardial
ischaemia allowing accurate risk
stratification in UK. |

What is Thallium
Scanning? |
A radioactive
substance, called a tracer, is
injected into the bloodstream. The
tracer used for this scan is called
thallium and it attaches to the
muscle cells of the heart. If an
area of the heart does not have a
good blood supply, then that area
will not receive as much thallium
scanning in UK.
This will show up as a darker area
on the picture taken by the camera. |

Technetium Heart
Scans |
The technetium heart
scan is used to evaluate the heart
after a heart attack. The technetium
heart scanning is a nuclear heart
scanning, which means that it
involves the use of a radioactive
isotope which targets the heart
scanning. The
technetium heart scans use
technetium Tc-99m stannous
pyrophosphate. |

MIBI Scan, MUGA
scanning, Thallium Heart SCAN
(Myocardial Perfusion Scan) |
There are two main
types of heart studies performed at
the Institute. A MPI scan to look at
blood flow within the heart muscle
and a MUGA scan. After the exercise
test the scan will either be
performed immediately (THALLIUM
scan or scanning). A MPI scanning look at blood
flow within the heart muscle. MPI
Scan is also called THALLIUM
Scanning, MIBI Scans or MYOVIEW
scan in UK. |

Diagnosis of coronary artery disease
by radionuclide myocardial … |
Despite advances in the
understanding of the pathophysiology
of atherosclerosis scans and an applaudable reduction in
cardiovascular mortality over the
past 30 years, coronary artery
disease (CAD) remains an important
cause of mortality and morbidity in
the UK. While primary prevention of
CAD is a priority for modern
medicine, so too is the need for
development of non-invasive
techniques for imaging of myocardial
ischaemia. |

Thallium scan definition - Medical
Dictionary definitions of … |
Thallium scan or scans: A method of examining
the heart to obtain information
about the blood supply to the heart
muscle. In the scan, special cameras
take a series of pictures of the
heart. Radioactive thallium is
injected into the bloodstream and
serves as a tracer. The tracer
attaches to certain cells and makes
them visible to the special camera.
The tracer attaches to the muscle
cells of the heart so the imaging
camera can take pictures of the
heart muscles. If an area of the
heart does not receive an adequate
flow of blood, the cells in the
underserved area do not receive as
much tracer and it appears as a
darker area on the picture taken by
the camera.
The thallium scan, scanning, scans can be done in two
basic ways, namely as a:
Stress exercise thallium scan -- one
exercises on a treadmill to stress
the heart by making it go faster and
more strongly ; or
Adenosine thallium scan -- one
receives adenosine (or another
medication) to similarly stress the
heart |

Thallium scan - General Practice
Notebook |
A
cardiac perfusion scan measures the
amount of blood in your heart muscle
at rest and during exercise. It is
often done to find out what may be
causing chest pain. It may be done
after a heart attack to see if areas
of the heart are not getting enough
blood or to find out how much heart
muscle has been damaged from the
heart attack. During the scan or
scanning or scans, a
camera takes pictures of the heart
after a special test medicine
(radioactive tracer) is injected
into a vein in the arm. The tracer
travels through the blood and into
the heart muscle. As the tracer
moves through the heart muscle,
areas that have good blood flow
absorb the tracer. Areas that do not
absorb tracer may not be getting
enough blood or may have been
damaged by a heart attack. |

The
scan is carried out in two parts. In
the first part, your heart needs to
be under mild stress, so you will be
asked to do some light pedalling on
an exercise bike. If you are not
able to do the exercise test, the
doctor will give you a drug which
stresses your heart in the same way
as exercise. Then you will have an
injection containing a small amount
of a radioactive material such as
thallium scanning or scans, technetium or tetrofosmin,
which is what shows up on the scan.
The amount of radioactive material
is so small that it is not harmful.
Pictures of your heart are taken
using a special camera. The camera
detects the x-rays or gamma-rays
coming from the tracer in your body.
This takes about 15 minutes and you
will need to keep very still. |

Myocardial perfusion scan |
For 24
hours before the test or scans avoid foods
and drinks containing caffeine, eg
coffee, tea, (including
decaffeinated) coke, Pepsi,
chocolate bars and drinks. On the
morning of the test only drink water
and have no food. Cheese or ham
sandwiches, a chocolate bar or
chocolate biscuits should be brought
in on the day for eating when told
to. Sensible shoes and clothes
should be worn so the exercise test
can be carried out easily and
safely. Separates are advisable for
women so heart monitors can be
attached easily. |

myocardial perfusion scan |
A
myocardial perfusion scan or
scanning is used to
evaluate coronary artery disease,
which is a narrowing of the blood
vessels that supply oxygen to the
heart muscle. As this disease
progresses, the heart scans may not
receive enough oxygen at times,
especially when it's under stress.
This may result in a chest pain
called angina.
The scan uses radioactive substances
(radionuclides), in the form of
thallium and technicium, which can
be used to produce pictures of a
patient's heart. When the
radionuclide is injected into the
bloodstream, it travels to the heart
muscle through the coronary
arteries. This process can be
visualized by a special camera. |

A
myocardial perfusion scan is a type
of nuclear medicine procedure. This
means that a tiny amount of a
radioactive substance, called a
radionuclide (radiopharmaceutical or
radioactive tracer), is used during
the procedure to assist in the
examination of the tissue under
study. Specifically, the myocardial
perfusion scan or scans evaluates the heart’s
function and blood flow. A
radionuclide is a radioactive
substance used as a "tracer," which
means it travels through the blood
stream and is taken up (absorbed) by
the healthy heart muscle tissue. On
the scan, the areas where the
radionuclide has been absorbed will
show up differently than the areas
that do not absorb it (due to
decreased blood flow to the area or
possible damage to the tissue from
decreased or blocked blood flow). |

Heart
Scan Info. |
Myocardial Perfusion imaging scans has
undergone numerous changes over the
past decade. It still involves two
main parts. They are the Stress and
Resting Studies. The traditional
"Stress/Rest Thallium Scan" has, in
many institutions been replaced by
scans using Technetium (Tc99m) based
myocardial perfusion (heart blood
flow) agents. The first technetium
based agent to gain acceptance was "Sestamibi"
(or MIBI) in London. |

Myocardial Perfusion Imaging (Stress
Test) Patient Guide |
Myocardial Perfusion Imaging Scans stress
test is usually done in Nuclear
Medicine Departments or Cardiac
Clinics. They may perform the test
on an outpatient or inpatient basis.
The test involves an injection of a
small amount of radioactive material
which circulates in the bloodstream
and shows if your heart muscle is
receiving adequate blood supply
under stress and/or rest conditions.
The radioactive injection is a clear
liquid called MYOVIEW (Tc99m
Tetrofosmin for injection). Another
material which could also be used is
called Thallium. (See product
