What is the difference between scanning PET and Cat?
PET and CAT scanning technologies are types of medical imaging used to view various aspects of the inside of the body without the need for surgery. Positron emission tomography (PET) scan detects very weak radioactive particles that have been introduced into the body to show how different parts of the body work. Computer tomography (CAT or CT) Scanning uses X -rays to create a collection of static images that can be combined with a computer and create a three -dimensional (3D) image of the inner structures of the body. Although there are two very different forms of medical imaging, many times the scanning of PET and Cat will be used in tandem to get a precise look at how the body works. Cat Scan uses a refined version of X -ray to pass the beams through the body; These rays are then recorded sensors in the scanner. The rays detect different bone, muscle and tissue densities. The THEN takes all the information and can either display it as a sequence of frames that went along the body axis or may digiTalically connect the images together and extrapolate a 3D image that can be handled and rotated by a doctor.
PET scan uses another method of obtaining image data from the body. The first step is the injection of the patient with very weak radioactive particles, which are built into the substance designed to be absorbed into any part of the body, will be displayed. Over time, the body will move radioactive particles to the target area. The PET scanner is able to detect particles A, as well as CAT scanning, can create a 3D image of the body activity. The resulting images do not show the physical composition of the body, but instead indicate how chemical processes of the body work.
Use of PET and Cat scanning allows you to have a body image that shows bones and internal organs, as well as the movement of molecules in these structures. PET scan shows functioning, so it can determine live tissue, cancer and tumors. ScanEC, as it shows the shape of the inner elements, can detect bone fractures, abnormal growth and larger tumors.
PET and CAT scanning technologies have certain disadvantages. CAT scanning is unable to detect abnormal growth and tumors that are very small. The disadvantage of PET scanning is that because radioactive particles move, it may sometimes be difficult to accurately insulate the location of the problem. Regardless of the use of PET and CAT scanning, it has made it possible to detect and diagnose many types of diseases before it can be done by other methods.
