Positron emission tomography (PET) is one of the most promising medical imaging technologies currently available in the medical world. It uses a small amount of radioactive tracers or radiopharmaceuticals to visualise molecular processes in the body. By measuring changes at the cellular level, the modality may help evaluate the disease before other imaging tests. It is an accurate imaging method that helps in the diagnosis, staging, restaging, and therapeutic monitoring of many common cancers. What is PET/CT scanning? PET imaging or a PET scan is a type of nuclear medicine imaging. It combines computed tomography (CT) and PET in one single imaging method and presents results that help doctors in making treatment decisions. While the PET image reveals the functioning of the body, the CT image tells about the anatomic structure. If you live in Delhi-NCR, you can do an online search to know PET CT scan price . How does a PET-CT work? For this test, a PET radiotracer 18F-fluorodeoxyglucose...

Ultrasound, also known as sonography, is a non-invasive imaging test that is widely used for diagnostic purposes. Ultrasound uses high-frequency sound waves to create real-time images of internal organs and soft tissues, such as blood vessels. The images are created by a computer that captures and processes the echoes returning from the body. Unlike x-rays and MRIs, ultrasound does not use radiation, making it completely safe and a commonly used diagnosis procedure. Why do you need an ultrasound scan? Your doctor may recommend ultrasound to have an overview of the body area they will be checking. There are many reasons why you may need to take up ultrasound scan. The two major types of ultrasounds recommended include: Pregnancy ultrasound Doctors may recommend it for reasons such as: Confirm the pregnancy Assess the baby’s size and position Find out if you are pregnant with more than one baby Estimate gestational age or duration of the pregnancy Screen for Down syndrome Evaluate birth ...

A magnetic resonance imaging (MRI) scan is a non-invasive imaging method that uses powerful magnets, radio waves and a computer to create detailed images of the inside of the body. These scanners are often used to examine various body parts, such as joints, breasts, heart, blood vessels, brain, spinal cord, bones, and internal organs, to detect anomalies and other conditions. How MRIs work MRI scanners use powerful magnets to align water protons in the body with the magnetic field during the scan. During the realignment, protons emit radio signals that get translated into detailed images by a computer. These images provide crucial insights into the body area being examined. Contrast vs. non-contrast MRI: To create better images, sometimes the doctor may order a contrast scan. For this, a contrast dye, typically gadolinium, is injected before an MRI to enhance the visibility of internal structures or detect subtle tissue variations. The injectable dye helps highlight areas of inflammati...

A lipid profile test, also known as a cholesterol test, is a blood test that measures the amount of certain lipids in the blood. Lipids are the fats that the body uses as a source of energy for proper functioning. However, their high levels can lead to cardiovascular and heart complications. This test is used to evaluate the risk of cardiovascular diseases like heart attack, heart disease and stroke, and as an aid in diagnosing and managing lipid disorders. What are some important tests in a lipid profile?  The four main components of the lipid profile test are total cholesterol, triglycerides, high-density lipoprotein (HDL) and low-density lipoprotein (LDL). High cholesterol can lead to a build-up of plaque in the arteries, causing obstruction to the flow of the blood. These deposits can cause clots leading to heart attacks or strokes. Blocked or slowed blood flow can cause angina, peripheral artery disease, and other serious complications. If you want to know lipid profile test ...

An SGPT test is a blood test done to find out the amount of serum glutamate pyruvate transaminase (SGPT) enzyme in the blood. The SGPT enzyme is mainly found in the liver and is known to perform many functions. The body uses the Alanine Aminotransferase (ALT) to break the food into energy. Normally, the ALT levels are low; however, in a situation where the liver becomes inflamed or damaged due to certain medical conditions, it releases the enzyme ALT into the bloodstream. A small amount of ALT is also found in muscles, kidneys, and other organs. Since this test alone can’t provide a complete picture of your liver’s health, it is commonly ordered along with other tests. Do an online search to know SGPT test price . It is important to monitor SGPT levels as it shows the current state of the liver. An elevated level of SGPT may indicate liver disorders, diabetes, heart issues, obesity and hepatitis C. The test may be done to find out conditions such as jaundice, hepatitis and liver cirrho...

An Electroencephalogram (EEG) is a non-invasive medical test that measures and records the electrical activity of the brain. It is a crucial diagnostic tool used primarily to detect abnormalities related to electrical activity in the brain, which can assist in diagnosing various neurological conditions. During an EEG, small electrodes are attached to the scalp using a special conductive paste or cap. These electrodes pick up the tiny electrical impulses produced by brain cells. The signals are then amplified and recorded by a computer, resulting in a series of wavy lines on a graph known as brain waves. The different patterns of brain waves can indicate different states of brain activity, such as awake, asleep, or experiencing a seizure. EEG Test are particularly useful in diagnosing conditions such as epilepsy, where abnormal brain activity is often detectable during and between seizures. They are also used to investigate other disorders that affect brain function, including sleep di...
