A PET scan is often done in conjunction with a CT scan. These tests show the structure of, and blood flow to and from organs. Unlike magnetic resonance imaging and computed tomography scans, which reveal the structure of the lungs, a PET scan shows how well the lungs and their tissues are working. The combination provides a color-coded image of the body's structure and function. CT scans take a fast series of x-ray pictures. Youll have a low dose CT scan done at the same time as your PET.

Cancer: PET scans can reveal the presence and stage of a cancer, show whether and where it The actual PET scan takes about 45 minutes. Doctors introduce a tracer into the system and areas with high chemical activity show up on the screen as bright spots. The scans can also evaluate the occurrence of colorectal, lymphoma, melanoma, and pancreatic tumors. PET scans create images which show where cells are particularly active in the body. Positron Emission Tomography and Breast Cancer staging. This is different than MRI and CT scans. Since the PET scan was fully booked for that week, they asked if the following Wednesday would be ok. That mean waiting just over a week for a PET scan. PET scan is an imaging technique that uses a radioactive tracer to locate tissue differences at a molecular level.

PET scan images can detect cellular changes in organs and tissues earlier than CT and MRI scans. PET scans show inflammation, infection, fractures all sorts of things. A small amount of radiation, called tracer, is put into your body before the PET scan. A positron emission tomography scan is a type of imaging test. The scan can detect changes in the body's metabolism and chemical activities. PET scans can detect areas of cancer that may not be large enough to show up on a CT or MRI scan. A lung positron emission tomography scan is an imaging test.It uses a radioactive substance (called a tracer) to look for disease in the lungs such as lung cancer.. Because malignant cells grow at a fast rate, they metabolize more sugar than normal cells. PET scans can show healthy and damaged heart muscle. PET scans use a radioactive tracer to show how an organ is functioning in real time. The substances used in PET scanning are not associated with any side effects, so you should feel no different after the scan. PET scans offer a much more detailed depiction of whats going on in the body. PET gets the images of the inside of the human body utilizing tracer positron-emitting radionuclide. PET scans can help detect cancer and how far it has spread. A PET-CT scan can sometimes show whether this tissue is active cancer or not. PET is very useful in detecting the activity of cancer. PET can measure blood flow, blood volume, oxygen usage, tissue pH (acidity), glucose (sugar) metabolism, and drug activity. PET scan, or positron emission tomography scan, is a functional imaging technique. The radiotracer does not cause any side effects or pain. The role of a CT or MRI scan is to produce an image which can pinpoint the exact location of specific activities in the body. Millions of PET scans have been done around the world without complication. From here, the PET scan is conducted to reveal the problems on a cellular level.
