Pleural Effusions

with the advancement in science and medical technology, physicians now have more tools at their disposal to detect and diagnose various types of cancer than ever before. While many have heard of MRI, CAT scans, and x-ray, PET scan is a very useful tool that actually shows more detail than other diagnostic tools.

positron emission tomography, or PET is a form of nuclear medicine slike.Tehnika produces three-dimensional, or 3D, images, or images of functional processes in tijelu.PET system detects pairs of gamma rays emitted indirectly positron-emitting radionuclide, or tracer, which was introduced into the body immediately before testa.Slika developed the test, including images tracer concentration, and then reconstructed on a computer analysis of three-dimensional view. In the latest scanners, the reconstruction is often produced with the help of x-rays, CT scans performed on patients during the same test and PET scan in the same machine even.

There are different biologically active molecules that can be selected for PET scanning. FDG is one of these molecules. When this molecule, which is a glucose analogue, has been chosen, the concentration of tracer shows the metabolic activity of tissues in terms of regional glucose uptake. Using this tracer results in the most common type of PET scan, but there are other tracer molecule that can be used in PET to show the tissue concentrations of many other types of molecules or cells of interest.

Like many of these techniques, PET is used as a recording of medical and tool istraživanje.Dijagnostički tool is used heavily in clinical oncology, where it is used for medical cancer and to search for metastases, or new places for spreading cancer. This type of imaging is also used to diagnose various diseases of certain diffuse brain. As an example, PET is used for recording diffuse brain diseases such as those that cause different types of demencije.Imaging system is also important for normal mapping of the human brain and heart.

as a research tool, PET is used in pre-clinical studies using životinje.Skeniranje allows repeated investigations into the same subjects. Although it is May seem intrusive, repeat testing is extremely valuable in cancer research as it results in an enormous increase in statistical data quality because it enables the subject to act as controls for that item, as well. PET imaging also reduces the number of animals needed for the study of matter.
