PET-CT Scan: Advanced Imaging for Accurate Diagnosis & Cancer Detection

pet ct scan
A positron emission tomography computed tomography (PET-CT) scan is a powerful imaging modality that depicts physiologic processes within the body. For this scan, a tiny amount of radioactive substance, called a radionuclide (radiopharmaceutical or radioactive tracer), is used. When the radiotracer enters the bloodstream, it gets absorbed by the organs and tissues and when it decays, it emits gamma rays. The PET scanner collects these signals and creates a 3D image of the body’s metabolic activity. At the same time, the CT scanner delivers a detailed anatomical image of the same area.

This scan is used all around the world and is advised in both cancer-related and non-cancer-related conditions. It is particularly helpful in evaluating and identifying cancer, and monitoring treatment progress. It is also used in evaluating different conditions related to brain and heart. Since this test helps provide a holistic view of the complete body anatomy, any abnormal activity in the body can be examined in detail. Multiple PET scans can be suggested to determine how the tumour is responding.

A PET-CT scan is a non-invasive procedure and preparation may differ based on the radiotracer used. Hence, it is important to follow the doctor’s advice. The most common tracer used in PET scans is FDG (a radioactive sugar). This means that eating or drinking anything with calories may affect the imaging results, and you may be required to do a repeat scan. It is important not eat or drink anything prior to the scan except for plain, unflavored, non-carbonated water or prescribed medicines. At the same time it is also important not exercise for 24 hours before the PET scan.

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 ...

PET-CT Scanning: Revolutionising Cancer Detection and Treatment Monitoring

Image
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 .

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...
