Things You Need To Know About PET Scan

There are questions with regard to PET-Scan. By and large the name of the scan in English is "positron emission tomography”. In nuclear medicine exam often called PET or positron emission tomography. The process of PET scan is pretty much the same as scintigraphy wherein the analyzing the functioning of an organ or a structure of the body is done by using a contrast product injected into the patient. The radiotracer gets activated by coming in contact with the organs and in the presence of an anomaly.

Images of these reactions are captured by a machine and reproduced on a computer screen. The three-dimensional reconstruction makes it possible to visualize the zones of high concentration of the tracer (zones in red). The doctor can identify an abnormality or pathology. As one of the primary advantage, A PET scan allows the obtaining of 3D cuts, which is not the case of scintigraphy. This comes out as a useful method in oncology for detecting or monitoring a tumor.

Why prescribe a tomography?

PET CT scan is mainly prescribed:

  • For the detection of metastases, to know the effectiveness of treatment put in place or to confirm a tumor recurrence when a blood test revealed an increase in tumor markers.
  • In cardiology to study the functioning of the myocardium (for example after a heart attack) or coronary arteries
  • In neurology to confirm the presence of brain damage and degenerative disease such as Alzheimer's or Parkinson's disease.

How does a PET scan work?

In terms of the time duration, the PET scan takes about two hours. Intravenous injection of the radioactive substance is the first step. The patient is kept laid down for one hour in a usual basis. It is the standard time required in order to have the contrast material to enter the body and reach the organs to be examined. The patient is then placed for about twenty minutes in a machine equipped with a ring-shaped opening whilst they are still lying on their back. That's when PET images are created. The results cannot be put out or discussed immediately as it takes some time for study and analysis of the image.

Some of the health conditions determined in PET scan are:

  • The presence and nature of tumor lesions, recurrence of the disease or metastasis of cancer at an early stage;
  • The presence of vascular disorders, post-traumatic changes, foci of epilepsy and Parkinsonism in the brain, as well as causes of dementia;
  • The viability of the myocardium (heart muscle) in ischemic heart disease, congenital heart defects.

The most important basic checkup!

First of all, the most basic checkups should be taken. Anyone who needs health checkups (blood pressure, blood sugar, cholesterol, etc.) or five cancer checkups (stomach cancer, colorectal cancer, liver cancer, breast cancer, cervical cancer) for cardiovascular risk factors should receive it. Ask for CBC with ESR cost in Delhi at diagnostic labs in Delhi before undergoing any health checkup.

Early check-up for lung cancer is needed because you are a smoker!

As a smoker, the most important checkup you should receive is whole PET CT scan in Delhi for 'lung cancer'. Smokers' risk of lung cancer is known to be about 23 times that of non-smokers.

The recommended annual checkups for smokers are:

-chest radiography

-analysis of blood and urine by KFT test

-electrocardiogram

-Mammography examination and vaginal cytology in women

It is important to go to the doctor once a year even if you do not have symptoms to do a complete checkup. This should be done above all by people with a family history of cancer, heart disease, diabetes and hypertension among other pathologies.

Vascular diseases are not overlooked

Smoking can cause coronary artery disease or cerebrovascular disease, the leading cause of death for adults. However, it can be diagnosed early through coronary artery CT scan, brain MRI / MRA, and carotid artery ultrasound test. One should always compare the cost of 3T brain MRI and MRI head cost in Delhi before finalizing any radiological procedure for himself.

In particular, in the case of coronary artery CT, diagnostic usefulness for coronary artery stenosis at a risk level is known to be four times higher in smokers than in the general public, and if such stenosis exists, progression can be prevented through active intervention such as stent insertion. In particular, when the risk factors of other cardiovascular diseases such as hypertension, diabetes, and hyperlipidemia are accompanied, the above test may be considered.

Health functional food

Many smokers take multivitamins or look for health supplements such as beta-carotene and tocopherols to prevent the health risks associated with smoking. However, many studies suggest that mortality with lung cancer due to smoking is common even with those people who were having multivitamins for years, so it is not recommended to take it unless it is a special case.

The most obvious preventive measures to quit smoking

It is common knowledge that smoking is bad, but in many cases, it is not easy to quit smoking despite the repeated decision to quit smoking every year. This is because smoking is not just a habit, but a disease called nicotine addiction. Effective drugs have been developed by medical experts to help quit smoking. Smoking cessation clinics are another alternative option that havehelped chronic smokers to quit smoking.
