PET-CT Scans Explained: How They Detect Cancer and More

PET-CT Scans Explained: How They Detect Cancer and More

In early cancer detection and accurate diagnoses of other serious health conditions, technology has always been our strongest ally. Among the imaging techniques, the PET CT scan remains an important and advanced investigation. So, what is a PET CT scan? How does it identify cancer? And where can I go to get reasonable PET CT scan services nearby, if ever?

In this blog, all about PET CT scans will be explained, focusing primarily on how they are essential for the early detection of cancer, the estimated cost range, and why Mahajan Imaging & Labs is best suited to give you quality PET CT scans.

What is a PET CT Scan?

A PET CT scan is the combination of two imaging techniques—positron emission tomography (PET) and computed tomography (CT). The CT scan shows the detailed pictures inside the body, while the PET scan shows the functioning of tissue and organs at the cellular level.

These two imaging techniques work in synergy—CT provides a structural map of the body, while PET highlights functional changes at the cellular level. In contrast, the PET scan illuminates areas of abnormal metabolic activity that often correlate with pathological states such as cancer.

How Does a PET CT Scan Detect Cancer?

Cancer cells are unique—they grow faster and consume more energy than normal cells. PET scans exploit this by injecting a trace amount of radioactive sugar into your veins. Since cancer cells consume more sugar than normal cells, they appear as hot spots on the PET scans.

With the use of CT scans, physicians are able to get a clear picture not only of where the suspicious motion is but also of how it fits in with your body. The double imaging is beneficial.

  • Enable early detection of cancer, when treatment outcomes are typically more favorable.
  • Identify the definitive stage of cancer.
  • Track how well the treatment is progressing.
  • Identify any recurrence of cancer following treatment.

Because of its sensitivity and high accuracy, PET CT scan cancer detection is usually considered to be the gold standard in oncology diagnosis.

Other Uses of PET CT Scans

Although PET CT scans are most well-known for the diagnosis of cancer, their uses go beyond the oncology department. Physicians also utilize them to:

  • Diagnose neurological conditions like Alzheimer's disease.
  • Diagnose cardiovascular disease using blood circulation and heart muscle activity monitoring.
  • Identify infections and inflammatory conditions.

This versatility makes PET CT scans an important diagnostic tool for a wide range of serious diseases.

Frequently Asked Questions

What is a PET CT scan, and how is it different from an ordinary CT scan?

A PET CT scan integrates metabolic imaging (PET) with precise anatomical imaging (CT), enabling physicians to visualize the structure as well as the function of tissues. A standard CT scan reveals anatomy but not function of tissues.

Is a PET-CT scan safe?

Yes, PET CT scans are safe. They involve a very small dose of radioactive tracer, which is rapidly removed from your body. The benefits of early and precise diagnosis far outweigh the very small dose of radiation many times over.

How do I prepare for PET-CT scan?

You can normally be asked to fast 4-6 hours prior to the test and to refrain from exercise. Always follow what your doctor says for maximum results.

How soon can PET CT scan results be obtained?

Here at Mahajan Imaging & Labs, you can have your results in 24 to 48 hours, so your doctor may make informed decisions regarding your treatment.

Can cancers be diagnosed early through a PET CT scan?

Yes, PET CT scans are very sensitive and can detect early or small cancers by detecting abnormal metabolism before physical symptoms are present.
