PET-CT Enables to Detect Cancer in its Early Stages

What is PET-CT?

There are organs that are difficult to examine with existing PET scan devices. Therefore, it was required to perform additional examinations, such as CT and MRI scans.Our hospital implemented the most advanced device, PET-CT, which can take images with PET scan devices and CT scan devices (X-ray computed tomography equipment) at the same time.PET-CT allows to precisely diagnose the size and position of a tumor and metastasis of cancer. Thus, it can detect cancer in its early stages and greatly help for treatment planning.

Advantages of PET-CT

  1. Cancers that are very small in size and difficult to detect can be found.
  2. Duration of examination can be short.
  3. Patients experience almost no pain and discomfort.
  4. It can diagnose malignant and benign tumors.

How the Examination Works

The frequency of cancerous cell division is more than the healthy cells. Therefore, cancerous cells require 3-8 times more glucose than what healthy cells need.PET-CT exam utilizes this unique characteristic of cancer cells and creates an image.Medicine called FDG is injected into the patient and it is carried through out the body. Cancerous cells tend to take up larger amount of FDG.With PET camera, gamma rays emitted from FDG is captured to make an image.

What Kind of Conditions Can PET-CT Detect?

  1. Epilepsy
  2. Malignant tumor, including malignant lymphoma. However this does not include detecting early stages of stomach cancer.
