How Do I Interpret My PET Scan Results?
PET is particularly suitable for early diagnosis of diseases, detection of subclinical lesions, and evaluation of treatment effects without morphological changes. At present, PET has shown particularly important value in the diagnosis and treatment of three major types of diseases: tumor, coronary heart disease and brain disease.
- PET Chinese translation is called "Pate", which is a non-invasive imaging technology used to detect the distribution of radioactive nuclei in the body.
- Name
- Positron emission computed tomography (PET)

Clinical significance of positron emission computed tomography (PET)
- Traditional medical imaging technology shows anatomical and structural changes caused by diseases, while PET shows changes in human functions. In other words, if the anatomical structure of the human body has not changed, the traditional imaging technology is powerless to diagnose the disease. In fact, the occurrence of diseases is accompanied by functional changes in biochemical processes, and these changes often precede changes in anatomical structure; there are also some diseases such as Alzheimer's dementia, Parkinson's disease, etc., which have no obvious structural changes themselves. Traditional Medical imaging cannot show these functional changes. PET can uniquely display functional changes, so it has unparalleled advantages for earlier detection and diagnosis of diseases; in addition, PET can also perform 3D dynamic and whole body imaging, which can find problems that cannot be found in other tests, preventing "Ye Zhanmu, without seeing Mount Tai" makes up for the lack of traditional medical imaging.
Positron emission computed tomography (PET) considerations
- (1) You must register with the tumor radiotherapy center at the scheduled time and cooperate with the doctor to prepare for the examination; if you do not arrive on time, others will be arranged to perform the examination first, and your examination will be postponed. (2) Fast for 6-8 hours before the scan, drink a small amount of boiled water, and avoid coffee, tea and alcoholic beverages two days before the heart test; do not do strenuous activities 1 day before the scan. (3) Please bring your medical records and X-rays, CT films, MRI films, etc. At that time, the doctors in the PET-CT room will inquire and record your medical history, treatment and allergy history in detail; blood glucose will be checked for you before the scan. If you have a history of diabetes, please let us know. (4) Due to the production, transportation, and other unpredictable factors of PET-CT imaging positron medicine, your inspection may be postponed or postponed. Please give your understanding and support. PET-CT staff will complete the inspection for you as soon as possible. (5) You need to receive intravenous injection of positron medicines, please rest assured that the radiation dose of these medicines is within a safe range. After the injection, you must lie in the PET-CT waiting room for about 60 minutes. After the drug is metabolized in the body, perform a PET-CT scan. During the scan, you should lie on the scan bed. You cannot move during the test. (6) After the scan, please do not leave the PET-CT waiting room by yourself, the medical staff will inform you if you need to leave for further examination; please complete the inspection and leave with the permission of the medical staff. (7) If you have other questions, you can ask the staff. (8) If you need to postpone or cancel the examination due to special circumstances, you must inform the appointment room 24 hours in advance, so as not to affect your or others' medical consultation.
