Advantages and Disadvantages of a PET CT Scan

Advantages and Disadvantages of a PET CT Scan Powered By Docstoc
					A PET CT scan is a very important part of modern medicine. It is actually two
medical imaging scans packaged up together for the purpose of creating a more in
depth picture of the human body. The PET scan involves exposing the body to
radioactive material that results in gamma rays being emitted from the part of the
body being investigated. These energy rays can be detected and analysed and from
this a clear picture can be gleaned of the condition of the organs, cells and tissue in
that particular area. This unique function makes a PET scan extremely valuable in
measuring and detecting cancerous growths and tumors in the body.
  When combined with a CT scan, the end result is extremely detailed. A CT scan uses
X-rays to provide a picture of the inside of the body. This makes locating tumors and
abnormalities in the body much easier. By combining the two images (the PET scan
and CT scan) a doctor receives an even fuller and more complete picture than when
using just one or the other independently of each other. This ensures more accurate
diagnoses can be made and more effective treatment given.
  There are a number of benefits of a PET CT scan. First and foremost the information
that is produced in this way is completely unique, and would be out of reach
otherwise. There is no other scan or combination of scans that can provide as detailed
and full a picture as that of a PET CT scan. Using imaging software and scans in this
way is a much cheaper alternative than carrying out surgery to look into the body.
Sometimes an investigative surgery will be unavoidable, but this is usually a last
resort as it is more time consuming, more expensive and a great deal more difficult for
the patient who may takes days or even weeks to recover. A PET CT scan can be
carried out on an outpatient basis so it provides the minimum inconvenience to the
patient.
  PET scanning in particular, regardless of whether or not it is combined with a CT
scan, provides intricate details of the body on a cellular level. This allows a disease or
illness to be detected very early on, more so than other modalities are able to provide.
When combined however, a PET scan and CT scan are extremely accurate. They can
be performed at the same time, the patient does not even have to change positions
which means there is very little room for error. This also makes it one of the most
convenient medical imaging methods available. Software developed for reading data
from a PET-CT allows for the metabolic (PET) and Anatomical (CT) data to be
aligned one on top of the other giving the radiologists the most complete information
possible.
  As for disadvantages, well there aren't really any. Yes the patient is exposed to
radioactive material, but this is such a small amount that it has no long term side
effects. Nuclear medicine has been in existence for at least 50 years, and during that
time there have been few serious problems arise from this type of treatment. Women
who are pregnant may be unsuitable for a PET CT scan, but otherwise it is an
extremely safe and effective procedure.
  All medical imaging software is valuable to doctors and healthcare professionals, but
none more so than that developed for reading a combined pet ct scan. The PET scan
can provide detailed information about any abnormal cells - in this respect it can
detect abnormal cells, the speed at which they are developing and how much they
have spread. A CT scan provides a detailed image of the body which provides a map
and directions to the location of the cells. Working as a double team allows doctors to
make better treatment plans and provide the most appropriate care for their patients. It
is particularly effective as one of the tools used in providing oncology solutions and is
also useful in a multitude of medical disciplines.
  Kathryn Dawson writes articles for Mirada Medical Limited, a developer and
provider of powerful medical imaging software and solutions which are able to
combine pet ct scan or SPECT CT scan data for detailed analysis. Mirada is able to
help clinical oncologists to better understand and characterise a patient's condition
through their powerful oncology solutions.
