Full
Body Scanning
Currently,
full body scanning is a popular subject for discussion on television
and radio programs. Full body scanning
gets much of the attention as it is keyed to disease screening. The medical
imaging method most frequently under discussion is Electron
Beam Tomography, EBT, for "full body" scans. However,
CT Scans, employing a computer helical
CAT scan is also used for a wide range of body screening. It may
also be referred to as "spiral
scanning." Both are rapid and non-intrusive for the patient
and provide almost immediate results.
In the EBT
process, the patient lies on a table fully-clothed and an electron beam
traverses the body area in seconds. Exposure to radiation is minimal
and produces 3-dimensional images for examination by the technician or
physician. The exceptionally detailed graphics may be viewed from every
possible angle and images may be stored, filmed or transmitted.
In spiral
CT scans, the x-ray tube rotates around the reclining patient as the examination
table moves forward through the scanner. Since the tube is rotating while
the patient moves through the x-ray it provides a spiral view of the body
and thus derives the term for the scan. The process is rapid and efficient
and may be applied from head to toe.
In EBT
scanning, the term "full body scanning" has been applied to
a scan of the vital organs. The body area covered in the scan extends
from the neck and shoulders to the top of the hips.
EBT
is now one of the major screening devices for the detection of coronary
artery disease. Faster than the basic CT scan,
EBT has been approved by the FDA
and is considered ideal for early detection of calcification in coronary
arteries. The screening allows physicians to act promptly to initiate
preventive measures that might not ordinarily be revealed in early stages
of a disease.
FDA has
cleared full body scanning for
early lung cancer detection. Many
forms of tumors, intestinal irregularities, and disorders of the liver
and kidney's may also be found at early stages, allowing for prompt attention.
