PET-CT is an advanced medical imaging technique that combines two types of scanning: one that measures the metabolic activity of cells and another that provides detailed images of anatomical structures. This combination allows doctors to precisely identify areas affected by the disease and assess the response to treatment.[1] It is an extremely valuable research tool, and below you will find out when and what it can be used for.
What is PET-CT and how does it work?
As previously mentioned, PET-CT combines two types of scanning: positron emission tomography (PET) and computed tomography (CT).
Positron emission tomography scans the metabolic activity of cells and involves injecting a light radioactive isotope (tracer), which emits positrons, into the patient’s body. This tracer accumulates in cells with increased metabolic activity, such as cancer cells, and allows their detection. Computed tomography (CT) involves the use of X-rays to obtain detailed images of the anatomical structure of tissues. This helps to find precisely the area of interest found in the previous step. By combining these two technologies, PET-CT provides a complete image, both at the cellular and anatomical level.

Why is the PET-CT scan used?
PET-CT scanning is an extremely valuable diagnostic procedure in current medicine. One of the most common uses of this technology is in the detection and treatment of cancer. PET-CT plays a vital role in the diagnosis of cancer, as it can identify the presence of malignant tumors in the body. It is particularly useful in detecting metastases, that is, cancer cells that have spread to other parts of the body. It can also help determine and plan the right treatment for each patient. It can also show whether a particular cancer treatment is effective or not.
Another area in which PET-CT is often used is cardiology. It can assess the blood flow to the heart, enabling, for example, the detection of areas where there is insufficient blood supply or those affected by a heart attack, identifying areas of the heart muscle where need for coronary angioplasty or coronary bypass surgery, and risk of cerebrovascular accident.
PET-CT is also used in neurology, where it is used to detect and evaluate brain changes, helping, among other things, to distinguish Alzheimer’s disease from other types of dementia. It can also be used to detect diseases or inflammatory processes in the body.
Advantages of using PET-CT in diagnostics
One of the main advantages of this examination is that it allows early detection of various conditions, which helps to establish an effective treatment plan. The high accuracy of the images obtained is another major advantage of PET-CT. By combining the functional and anatomical data provided by the two types of scanning, images are obtained that allow accurate positioning and detailed assessment of the disease.
It plays an important role in treatment planning and avoiding exploratory surgery. It is also effective in assessing response to treatment, which helps to personalize it.
PET-CT plays a vital role in diagnosing a wide range of conditions by providing detailed images of the body at a cellular level. This technology makes it possible to detect health problems at an early stage, allowing for quick and effective treatment.
