Single Photon Emission Computed Tomography (SPECT): Early detection of brain lesions

In modern medicine, the possibility of early detection and accurate diagnosis of brain lesions is of great importance for successful treatment and prevention of possible complications. One of the innovative methods used in diagnostics is single photon emission computed tomography (SPECT). This method allows you to obtain information about the functional activity of the brain and identify the initial stages of damage associated with impaired blood supply.

SPECT is based on the use of a radioactive tracer that binds to specific molecules in the body. In the case of a brain test, the patient is injected with a chemical tracer that can bind to glutamate, a substance released by damaged brain cells. The radioactive tracer allows tracer activity to be tracked and recorded in different areas of the brain.

Carrying out a SPECT scan requires specialized equipment, consisting of a gamma camera and a computer data processing system. A gamma camera records the emission of photons emitted by the radioactive tracer and creates a three-dimensional image of the distribution of the tracer within the brain. Once the data is collected, the computer system processes the information and creates detailed images showing the functional activity of the brain and where there is increased glutamate.

One of the main advantages of SPECT is its ability to detect changes in the brain at early stages when other testing methods may not be effective. Elevated levels of glutamate may indicate initial brain damage, which can cause various neurological diseases. Early detection of such changes allows doctors to take measures to prevent further progression of the disease and preserve healthy brain cells.

Thanks to the data obtained, SPECT also makes it possible to determine the location of damage and estimate its volume. This is information that is important for developing an individual treatment plan for each patient. Doctors can neutralize the damaging effects of glutamate with special medications aimed at reducing it, which helps preserve healthy brain cells and reduce possible complications.

However, it should be noted that SPECT is not a high-resolution technique and does not provide structural information about the brain that another technique such as magnetic resonance imaging (MRI) can provide. Therefore, SPECT is usually used in combination with other methods to get a complete picture of the patient's brain.

Single Photon Emission Computed Tomography (SPECT) is a valuable tool in diagnosing early brain lesions. It allows you to identify damaged areas of the brain associated with impaired blood supply, and determine their location and volume. This allows doctors to take steps to prevent the disease from progressing and preserve healthy brain cells. In the future, with the development of technology and improvement of techniques, SPECT may become an even more accurate and informative tool for the diagnosis and treatment of various neurological diseases.

Single Photon Tomography Spect Single Photon emission computed Tomography is an X-ray examination of the brain performed to detect damage to the human brain in the early stages. When injured or stroked, brain cells can release glutamate, an irritating neurotransmitter that causes metabolic and circulatory disorders in the brain. This process can cause permanent brain damage. To solve the problem, a single photon emission computed tomography method was created. The method is based on the use of a special indicator that binds to excess amounts of glutamate in brain tissue and makes it possible to scan the brain. The scan results can determine the location and extent of the affected areas of the brain and the amount of glutamate released, which allows timely treatment and prevention of further irreversible damage to brain neurons.

The computed tomographic point emission (CTPE) method uses gamma emitters in xenon isotopes (or cesium) or in combination with TCPAC (methyltryptamine). Xenon complexes emit gamma photons 30–40 milliseconds after irradiation

Single Photon Imaging Tomography (SPECT) is an X-ray test that has recently been developed to detect the early stages of brain damage. This method allows you to detect the initial damage to the brain, the location and size of the resulting lesions and nerve damage.

SPECT tomography uses electron photons instead of X-rays, resulting in higher sensitivity and measurement accuracy. Thanks to this, SPECT tomography
