Positron emission tomography is a completely new way of radioisotope diagnosis in nuclear medicine, giving a number of capabilities and advantages to diagnostics and treatment in Germany.
The most important advantage is the possibility using positron emission tomography to identify the disease before the appearance of any common symptoms. That is, using positron emission tomography allows to obtain an image of the internal organs of patients, evaluate body metabolism, organ functioning, and to learn timely you are having a disease.
Positron emission tomography is of high importance in oncology, neurology, and cardiology. Timely diagnosis in those areas is extremely effective.
Other names for positron emission tomography are PET, PET Scan, and positron tomography. That is a new diagnostic method. Diagnostic images are made using positron emission. During positron emission tomography, a radioactive substance is used, and that substance emits positrons, which are positively charged particles.
Previously, that technique was used in cardiology. The method makes it possible to evaluate the changes that occur on the cell metabolism level. CT and MRI cannot do that. With PET method, you can learn about having the disease earlier, than if the diagnosis was performed by means of MRI or CT.
Today the method is actively used for the purposes of diagnosing cancers. Positron emission tomography plays a significant role in neurology. Presently some modern radiopharmaceuticals exist, which allow the body of the patient experience less radiation exposure, but, instead, to expand the clinical use of positron emission tomography.
That X-ray imaging gives a possibility to diagnose cancer. The radioactive glucose is injected to the body, and all the body's cells convert it. A distinguishing feature of cancer cells is having an increased metabolism, which requires a greater amount of glucose. In positron emission tomography, scanner detects cancer cells and displays them in the images.
The radioactive substance injected to the patient is harmless, and it will lose its activity after a couple of hours. The method lets us to know, why tumor markers increase in the body. Contrary, the studies of computed tomography does not give an answer to this question.
The main advantages of diagnosis in Germany are:
The method of diagnostics with PET is a necessary complement to the classical methods of radiation diagnostics. The core of method is imaging technique, which enables to get different sections of the body condition.
The method of diagnosis is especially valuable for lymph cancer, as it helps to choose the most suitable form of treatment. PET will help even when other diagnostic techniques are not effective. For example, when X-ray method detects shader, it can only indicate a possibility of the presence of cancer, but PET allows either to confirm or refute the actual presence of the disease. Furthermore, the method allows to determine the size of the tumor, as well as to learn about the spread of cancer cells to other organs.
This method has a highest accuracy rate, 80-95 per cent. Due to the extremely high accuracy of diagnosis, it is possible to avoid surgery.
In cardiology, PET is used to check a condition of the heart muscle. As a result, it is possible to decide on the matter of heart surgery.
PET Scan is also widely used in case of neurological issues. It enables to detect in time brain disorders, which then lead to senile dementia. In addition, the method can reveal the Parkinson's Disease. With the data received from imaging, the doctors in Germany will appoint a highly effective therapy.
Positron emission tomography also allows revealing the parts of the brain that are responsible for epilepsy. After the accurate examination it is possible to plan surgery of the epileptogenic areas with high degree of certainty. The specialists of German clinics conduct positron emission tomography to diagnose cancer, neurological, and cardiological diseases. German doctors have great experience and can help patients to recover.
