A spirometry test measures the volume of air inhaled and exhaled. Spirometry allows for the assessment of airway function. The spirometer, the apparatus used for this test, is connected to a computer that processes the data and allows you to get a result. It is primarily a test used to […]

Scintigraphy is a test based on gamma radiation. It is one of the techniques for imaging organs and also evaluating their function. The test uses radioactive isotopes, which are administered to the patient before the examination. The apparatus used for the test, called a scintigraph, has a radiation detector. The […]

Magnetic resonance imaging (MRI), like computed tomography (CT), is one of the modern diagnostic methods useful in detecting a variety of diseases. MRI allows a cross-section of the internal organs to be imaged in all planes. This is possible because the human body, like everything else in the world, is […]

It is an imaging method that uses X-rays (X-rays). A certain dose of X-rays is passed through the body, which after passing through it is projected onto a special X-ray detector. The detector in most cases is photographic (X-ray) film. X-ray examination is used to detect pathological changes in tissues, […]

Cancer markers are substances whose concentration and presence are associated with the development of cancer. These are substances secreted into body fluids, such as blood or exudates, or found on the surfaces of cells, both neoplastic and nonneoplastic. The latter are detected by histopathological examination of tissues. Tumour markers – […]

It is a radiological method of examining the breasts to detect changes in the breast structure. Like other radiological methods, mammography uses X-rays. This radiation is absorbed to varying degrees by different tissue structures. Loose breasts with a lot of fatty tissue can be effectively examined with a mammogram. On […]

Coronarography is a method of examining the coronary vessels of the heart. By visualizing the location and extent of narrowing in the coronary arteries, it allows an assessment of the severity of ischemic heart disease. The procedure is performed under local anesthesia. A catheter is inserted through the groin by […]

Electrocardiography is the study of the bioelectrical activity of the heart. Every living cell of the heart is a source of electrical energy. An ECG records changes in electrical voltages in the heart muscle. The currents generated in the heart pass through the tissues and can be recorded and stored […]

Electroencephalography EEG is a method of recording the functional currents produced in the brain. The EEG apparatus is equipped with special electrodes, which are placed on the head. These electrodes record changes in the potential of bioelectrical currents in the brain. The EEG enables to differentiate between organic and functional […]

Exercise stress testing is the evaluation of ECG changes during exercise. The ECG is known to change during exercise both physiologically and in disease states. Exercise testing primarily assesses the physical capacity of the body. Simultaneous ECG monitoring and blood pressure measurement during exercise allow assessment of cardiovascular fitness. Preparation […]
