PET-CT

Advanced imaging that combines metabolic and structural detail for precise diagnosis. You're in safe hands.

PET-CT Technology

A PET-CT scan is an advanced imaging technology that combines Positron Emission Tomography (PET) and Computed Tomography (CT) in a single scan. It captures both the metabolic activity of cells and detailed structural images of organs and tissues, helping doctors detect disease earlier and more accurately. This PET-CT technology is widely used in cancer care for diagnosis, staging, treatment planning, and monitoring response to therapy, and is also valuable in cardiology and neurology. At Manipal Hospitals, the Nuclear Medicine department operates PET-CT services with specialist radiologists and nuclear medicine physicians, supporting faster, more informed treatment decisions across specialities.

How It Works?

Before the scan, a small amount of a radioactive tracer (usually a form of glucose) is injected into the patient's bloodstream. Since cancer cells and other abnormal tissues often use more glucose than healthy cells, they absorb more of the tracer.

 

The PET-CT scan machine then captures two sets of images in one sitting: the PET component detects areas of high tracer uptake (indicating abnormal activity), while the CT component provides a detailed anatomical map. These two images are combined to precisely pinpoint the location, size, and nature of any abnormality, helping doctors distinguish between benign and malignant conditions with far greater clarity than either scan alone.

The doctor reviews the patient's medical history and explains why a PET-CT scan is being recommended, along with what to expect.

Technology Advantage

Advanced TechnologyConventional Approach
PrecisionHigh-precision hybrid imaging combines metabolic activity with detailed anatomical localisation.Primarily focuses on structural size and shape, which may not detect early cellular changes.
Visualisation3D fusion imaging maps tracer uptake and metabolic activity directly onto high-resolution anatomical images.Relies on separate structural images, offering limited insight into functional or metabolic activity.
InvasivenessNon-invasive diagnostic imaging requiring only a standard intravenous radiotracer injection.Non-invasive imaging may be followed by an invasive biopsy when further assessment is required.
RecoveryNo downtime; patients can generally resume their normal activities after the scan.No downtime from imaging, although additional scans or procedures may be needed when findings are inconclusive.
Patient ExperienceA streamlined imaging process provides structural and metabolic information in a single session, helping reduce the need for multiple visits.Multiple imaging appointments may be required to obtain both structural and functional information.
