MRI - magnetic resonance imaging
Magnetic resonance is a method used for imaging human body without radiation. It functions on the basis of radiofrequency waves and magnetic field. It is completely painless and suitable chiefly for imaging of brains, spine, large joints, vessels and abdominal organs.
The magnetic resonance examination is a relatively recent imaging radiological diagnostic method. Doctors opt for this method when they cannot make a final diagnosis based on other radiology methods. The device functions on the basis of a strong magnetic field - in our case 1.5 Tesla. By means of radiofrequency waves stimulate the hydrogen atoms in a human body, which are in larger concentration present in water, fat and bio molecules. The signal from these atoms is measured. The computer then uses special algorhythms to reconstruct the cross-section image of the body`s interior.
The advantage of this method is that the signal comes from inside the body, from various tissues and enables also imaging in any direction. In some cases imaging by a paramagnetic contrast agent is also required- depending on the reference diagnosis, data contained in the medical documentation and images displayed during the examination. The contrast agent is injected into a vein. During repeated imaging the effect of this agent on the survey of the patient`s tissue is observed.
MRI is completely painless and has no proven adverse effects.
- Duration of the examination: from 25 to 40 minutes

This is a computerised X-ray examination. It is particularly suitable for discovering alterations in the head, spine, skeleton, abdomen and chest. The device can provide spiral imaging, which is the standard method for X-raying abdominal organs and lungs.
Computerised tomography is based on X-rays, only it is not the usual imaging, but much more precise diagnostic method. The device contains an X-ray tube, which emits a narrow set of rays and rotates around the body. The rays travel through the body to the detectors, which measure the amount of X-rays that make it through.
Different tissues and organs have different permeability and based on the acquired data the computer reconstructs a very accurate image of a cross-section of the body`s interior. The examination comprises the images of cross-sections of a body and an opinion by a specialist radiologist.
This method enables very accurate diagnosis of various alterations and conditions after injuries. It is suitable mainly for severe and recent head injuries, complicated fractures as well as cancer and inflammations. Moreover, it enables scanning using a contrast material that is injected into a vein. The imaging is repeated and enables even more accurate diagnosis.
- Computerised tomography examination lasts from 5 to 15 minutes.

This method is used by our experts to discover quantitative decreases in bone mass. In addition to imaging, the examination includes also laboratory tests for bone digestive disorders (Ca, P, alkaline phosphatase) and a consultation with a specialist.
All guests are subject to an X-ray of two regions, usually the lumbar spine and the hip. In the case of artificial prosthesis or osteosynthetic material a palm X-ray is made.
Preventive discovery of osteoporosis signs enables the start of therapy and, if necessary, substitute hormonal therapy, and above all the adjustment of regular physical activity and diet. If a decrease in bone mass density is discovered in due time, osteoporosis can be prevented by preventive measures and, if necessary, treatment. Otherwise, if left untreated, it can lead to severe pain, fractures and, consequently, often death.
Ultrasound is a very widespread diagnostic method for examining the interior of the body. It is used by various specialists. It is suitable for imaging of abdominal organs, vessels, thyroid gland, joints, etc. The cardiologist conducts an ultrasound heart examination using the colour Doppler system and measures the blood flow parameters. The ultrasound is also a standard tool in gynaecology, especially in monitoring pregnancy. Furthermore, it is used by urologists for examination of the uropoetic tract, particularly for prostate examinations.
Ultrasound is a non-invasive, repeatable and completely safe radiology examination. It is based on ultrasound waves, i.e. sound with the frequency beyond the human hearing threshold (from 2 to 10 MHz). Ultrasound device emits into the body a narrow set of sound waves that bounce off of various tissues and internal organs and are converted by the device into a dynamic image displayed on the screen. During the examination the doctor moves the ultrasound probe, which enables them to examine the interior of the body from various angles. The ultrasound can be used also for examining moving organs (e.g. heart).
Prior to the examination a gel has to be applied onto the skin covering the examined area, as this provides a better contact between the probe and the body.
The duration of the examination depends on the type - for abdominal organs up to 15 minutes, for vessels up to 30 minutes.
The day before the ultrasound examination eat only light food, no legumes and meat, and before the examination drink a glass of tepid water.
For urology and gynaecology ultrasound examination the urinary bladder has to be comfortably full.
In the specialised outpatient clinic the following ultrasound examinations are provided:
- ultrasound of the abdominal organs
- ultrasound of the vessels
- ultrasound of muscles and joints
- ultrasound of the neck and thyroid
- ultrasound of genitalia
- ultrasound of kidneys, bladder and urethra
- ultrasound of the heart

Breast diagnostics usually include breast X-rays and clinical examination, since approximately 10% of clinical alterations are not detected by a mammograph, but are clinically palpable. Mammography is an X-ray examination, whereby alterations in breasts are discovered, i.e. alterations at the initial stage, smaller than one centimetre, which are not yet clinically palpable.
Since various alterations respond differently to different methods, a breast examination always combines a clinical examination and a mammography.
A preventive check-up is recommended to women older than forty and in the event of suspected induced alterations.
The X-rays have been for over a century used for surveying skeletal structures and changes within a human body. As the X-rays pass through the body, they weaken to a different degree and leave a trail on the film which is later developed and fixed. This method provides a survey of structures which weaken the X-rays either very much (bones and calcified structures) or little (air).
The X-ray is still the first diagnostic tool for discovering skeletal and other injuries.
