What Is PET Scan ?

A PET scan (positron emission tomography) is a type of imaging test that uses a radioactive tracer to look for changes in the function of cells and tissues. A tracer is a substance that is introduced into the body to make it easier to see certain areas or organs. The radioactive tracer used in PET scans emits positrons, which are tiny particles that collide with electrons in the body. This creates gamma rays that can be detected by a scanner and used to create images of the inside of the body. PET scans are often used to diagnose cancer because tumor cells typically have higher levels of activity than normal cells. They can also be used to check for treatment response, measure tumor size, and identify new tumors.

PET Scan is a nuclear medicine imaging test that uses a small amount of radioactive material, called a tracer, to look for disease in the body. A PET Scan can show how well organs and tissues are working. It can help find cancer, heart problems, and other diseases. A Positron Emission Tomography (PET) scan is a medical imaging test that helps physicians diagnose and treat diseases. PET scans use a small amount of radioactive material, called a tracer, to help physicians see how organs and tissues are functioning. The radioactive tracer is injected into the patient's body and travels to the organ or tissue being studied. Physicians can then see where the tracer collects on an image of the organ or tissue.

A PET scan is helpful in diagnosing cancer, heart disease, brain disorders, and other diseases. It can also help determine how well treatment is working. PET Scan is an acronym for Positron Emission Tomography. It's a type of medical imaging that uses a small amount of radioactive material to help diagnose and treat medical conditions. A PET scanner creates 3D images of the inside of the body. PET (positron emission tomography) scans use a small amount of radioactive material called a tracer to help doctors see certain areas of the body. The tracer is injected into a vein, and images are taken as it moves through the body.

PET scans are often used to find cancer because tumors absorb more of the radioactive material than normal tissue does. PET scans can also be used to measure blood flow, check how well drugs work, and see how active the brain is. A PET scan is a type of imaging test that uses radioactive tracers to look at the function and structure of organs and tissues in your body. A small amount of radioactive material is injected into your bloodstream and then scanned by a special camera. The camera creates pictures that show where the material has collected. This can help doctors see how well an organ is working or find tumors or other problems.

PET scan is short for positron emission tomography. It's a type of medical imaging that uses a radioactive tracer to look at organ function or tissue metabolism. The tracer is a small amount of radioactive material that's injected into the patient's bloodstream. It collects in organs and tissues, and a scanner detects the radiation emitted as it decays. This information is used to create cross-sectional images of the body that show how the organs and tissues are working. PET scans are most often used to detect cancer because tumors consume more energy than normal tissue and therefore have a higher metabolic rate. But they can also be used to evaluate other problems, such as heart disease, brain function, and joint damage.

PET scanning is a type of nuclear medicine imaging. A small amount of radioactive glucose (FDG) is injected into a vein and images are taken as the glucose moves through the body. Cancer cells use more energy than normal cells and therefore absorb more of the radioactive glucose. This allows tumors to be visualized on the scan. PET stands for Positron Emission Tomography. A PET scan is a medical imaging test that uses a radioactive tracer to look at organs and tissues inside the body. The tracer is injected into a vein, and images are taken as it moves through the body.

Simple Habits to Avoid High Cholesterol

High cholesterol is one of the leading causes of heart disease and stroke worldwide. In India, rising cholesterol levels are becoming more common due to sedentary lifestyles, unhealthy food habits, and stress. But the good news is—you can prevent high cholesterol naturally with a few simple habits.

In this blog, we’ll explore easy, everyday steps you can take to keep your cholesterol levels in check and protect your heart.

What Is Cholesterol?

Cholesterol is a fatty substance found in your blood. While your body needs some cholesterol to build cells and hormones, too much of the wrong type—called LDL (low-density lipoprotein)—can be harmful. It can build up in your arteries and increase your risk of heart disease and stroke.

There’s also HDL (high-density lipoprotein), which is the “good” cholesterol that helps remove LDL from your body.

Why High Cholesterol Is Dangerous

Clogs arteries and restricts blood flow
Increases risk of heart attacks and strokes
Can lead to high blood pressure
May affect kidney and liver function

The scariest part? High cholesterol usually has no symptoms. That’s why it’s called a silent killer and must be managed before problems begin.

7 Simple Habits to Avoid High Cholesterol

1. Eat Fiber-Rich Foods Daily

Soluble fiber binds with cholesterol in the gut and removes it from your body.

Best foods for fiber:

Oats and barley
Apples, pears, and oranges
Beans and lentils
Flaxseeds and chia seeds

Tip: Start your morning with a bowl of oatmeal and add a fruit—it’s a heart-healthy breakfast!

2. Stay Active Every Day

Physical activity boosts HDL (good cholesterol) and burns fat that raises LDL.

What to do:

Walk briskly for 30 minutes a day
Try yoga, cycling, or dancing
Use stairs instead of the lift
Take short walks after meals

Even small movements throughout the day matter.

3. Cut Down on Saturated & Trans Fats

These fats raise your LDL cholesterol quickly.

Avoid:

Fried food, chips, and baked snacks
Ghee-heavy sweets
Processed foods with “hydrogenated oils”

Choose instead:

Olive oil or mustard oil
Grilled or baked foods
Fresh fruits and nuts as snacks

4. Manage Your Stress

Stress affects your hormones and may raise your cholesterol over time.

Try this:

Practice deep breathing or meditation
Do relaxing hobbies like reading or gardening
Take tech breaks and sleep 7–8 hours daily
Talk to someone if you’re feeling overwhelmed

A calm mind supports a healthy heart.

5. Stay Hydrated and Cut Sugary Drinks

Water helps regulate body functions and weight, which both impact cholesterol.

Do this:

Drink 8–10 glasses of water daily
Avoid soft drinks and energy drinks
Switch to herbal teas or infused water

Too much sugar can raise triglyceride levels, a type of fat in your blood.

6. Quit Smoking and Limit Alcohol

Smoking lowers good cholesterol and damages arteries. Alcohol, in excess, can also spike cholesterol and blood pressure.

Tip:
Even reducing smoking or drinking frequency helps your heart function better.

7. Get Regular Cholesterol Tests

Don’t wait for symptoms. Get your lipid profile checked every year, especially if you have:

A family history of heart disease
Diabetes or high blood pressure
Obesity or unhealthy lifestyle habits

Suggested Test:
Lipid Profile Test by Thyrocare via SecondMedic.com – includes LDL, HDL, total cholesterol, and triglycerides with home sample collection.

Normal Cholesterol Levels:

LDL (Bad)	Below 100 mg/dL
HDL (Good)	Above 40 mg/dL (men), 50 mg/dL (women)
Triglycerides	Below 150 mg/dL

Tips to Book a Test via SecondMedic:

Visit www.secondmedic.com
Search for Lipid Profile Test – Thyrocare

Conclusion

You don’t need fancy diets or harsh treatments to manage cholesterol. Just a few simple daily habits can make a big difference in protecting your heart.

By eating better, moving more, managing stress, and staying hydrated, you can keep your cholesterol in check without medication in many cases.

Make your heart health a priority starting today!

Start following these simple habits to avoid high cholesterol and keep your heart happy for years to come.
