PET CT scan in Mumbai
PET stands for positron emission tomography, an imaging test that creates images of yoyur organs and tissues when working. This test uses a safe injectable radioactive chemical called a radiotracer and a device called a PET scanner. This scanner detects cells that absorb large amounts of the radiotracer, indicating a major health issue.  When conducted, a PET scan can measure important functions like blood flow, oxygen and metabolism.

  • Neurological disorders: Conditions such as epilepsy, Alzheimer's disease, dementia, and some tumours are detected with the help of a PET CT scan. 
  • Cardiac diseases: This scan also helps to examine heart muscle function and blood flow of damage right before a heart attack.   
  • Bone disorders: This scan also helps reveal changes in the bones that traditional imaging tests may not detect. 
  • Cancer: This scan can detect colon cancer, lung cancer, breast cancer, and other forms early and accurately. 
  • Infections and Inflammatory health conditions: Certain conditions, such as autoimmune diseases, unexplained fevers and chronic infections, may show distinct patterns that PET-CT scans can identify.

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...

What is SGPT 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...

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 .
