Many sources agree that pet scans are effective in finding cancer. These scans are said to help determine the location of tumors and whether or not they have spread.
several ways - CAT scans, PET scans, ECG scans...check it up with ur doctor
PET scans are used most often to find tumors and cancer. They're also used to look at brain activity and also used in heart disease diagnosis.
Yes and no. PET scans can detect the deterioration of brain cells such as in Alzheimer's Disease, etc. PET scans can also show that the 2 chemicals in the brain are not balanced and therefore can cause a person to become depressed (many different forms of depression) but it is up to a psychiatrist to determine what type of depression the person has.
PET scans can see inside the brain
PET scans or fMRI scans can indicate which portions of the brain are active at given points in time.
Positron emission tomography (PET) scans use radioactive substances that emit positrons to detect metabolic activity in the body. These substances are injected into the body and, as they decay, they emit positrons that interact with electrons to produce gamma rays. The gamma rays are then detected by a PET scanner to create detailed images of the body's functions.
PET scans are most commonly used to detect cancer, heart problems ( such as coronary artery disease and damage to the heart following a heart attack!
Barium sulphate is used in hospital scans to show the digestive system. It is very important in CT scans.
PET scans
In PET scans, antimatter (positrons) is used in the form of a radiopharmaceutical to create images of metabolic activity in the body. When the radiopharmaceutical is injected into the body, the positrons emitted from it annihilate with electrons in the body, producing gamma rays. These gamma rays are detected by the PET scanner to create detailed images of organs and tissues.
