Ultrasonography is a method of imaging organs known for many years, based on the phenomenon of reflection of acoustic waves from the encountered obstacles. Acoustic waves emitted by an ultrasound machine propagate through the human body and are subject to various phenomena, including the phenomenon of reflection. The ultrasound wave […]

Spectra Optical Coherence Tomography (OCT) using partially coherent light is an emerging medical imaging technique that has found many clinical applications in ophthalmology. One of the primary attributes of this technique is the high resolution of the images obtained, which means that in some applications OCT remains the only technique […]
Computed tomography is one of the modern methods of detecting and diagnosing many diseases. The essence of computed tomography is mapping organs in cross-section, i.e. taking pictures of individual layers of the organ. These layers have a very thin diameter (from 2 to 10 mm), which allows to detect even […]
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 […]
