Positron emission tomography is a new, modern imaging tool that is very valuable in diagnosing and evaluating cancer and a number of other body functions.

1. What is positron emission tomography?

Positron emission tomography (PET) is a special imaging tool that uses a special camera and tracer to display images that help reveal how tissues and organs are functioning. Positron emission tomography is often used to evaluate cancer, check blood flow, or see how organs are working.
Positron emission tomography images do not show detailed anatomy like computed tomography (CT) or magnetic resonance imaging (MRI). Therefore, PET scan is combined with CT or MRI scan to evaluate the exact location, more detailed information.

2. Indications for Positron emission tomography

Positron emission tomography (PET scan) is indicated in the following cases:
Diagnosis of nervous system problems such as Parkinson's disease, dementia.

Find the cause of convulsions, epilepsy. Suspected cancer: PET scan helps in early diagnosis of cancer, easier to detect than CT or MRI. Assess the extent of certain cancers, especially lymphoma or cancers of the head and neck, brain, lung, colon, or prostate. Cancer staging, progression and metastasis assessment Determine if a growth in an organ or tissue is likely to be cancerous? Positron emission tomography may also be done to see if surgery can be done to remove the tumor. Help diagnose Alzheimer's disease when symptoms are unclear or when a person has symptoms of dementia at a young age Assess myocardial viability in patients before reperfusion.

3. Clinical significance of the results

3.1 Normal Normal blood flow and normal functioning of organs htw[ngf. Flow and concentration of radioactivity according to body physiological characteristics.
3.2 Abnormalities Suspect seizures when areas of increased glucose metabolism or oxygen utilization are lower

A decrease in oxygen use and blood flow can mean a stroke has occurred. Suspect dementia such as Parkinson's disease, Huntington's disease, mental illness, when there is decreased glucose metabolism. Abnormal blood flow and oxygen use patterns could mean a brain tumor. Tumors on the body: Areas of increased glucose metabolism may mean a tumor is present. PET scans are useful in detecting cancer cell activity. This technique helps to evaluate the invasiveness of the tumor, and to monitor the effectiveness of the treatment of the diagnosed cancer. This technique can detect solid tumors in: Brain, cervix, colorectal, esophagus, head and neck, lung, lymphoma, pancreas, prostate, thyroid, other malignancies Currently, Vinmec International General Hospital has become a leading prestigious address in disease screening with modern techniques, proud to be the first private hospital in Vietnam to deploy Deploying modern and accurate diagnostic techniques with the most modern 128-sequence PET/CT system in Southeast Asia, giving accurate images and short scan time, the team of doctors are leading experts with high expertise. , experienced in creating trust for customers when experiencing medical examination and treatment services at Vinmec.
