CT Scan - Computed Tomography Europe

Spiral computed tomography uses roentgen rays (X-rays) to get detailed images of the inside of the human body like never before. As a result of advanced computer processing, diagnostic images can be created for any part of a patient’s body. Enough data can be collected in a CAT scan for the rendering of an advanced three-dimensional reconstruction of the examined tissue or organ.An X-ray lamp and detectors suspended on opposite sides of a perfectly round hoop are the main components of a CAT scanner. Entering the CAT scan on a special table, the patient is situated between the lamp and detectors. The X-ray lamp generates radiation, which passes through the patient’s body and is picked up by detectors. The fact that X-rays are differently impaired by individual organs/tissues of the body forms the collection basis for the image. The detectors are able to measure the level of this differential weakness and create a digital image of the results. The amount of data attained during the examination has grown due to the application of modern detectors, which has given greater processing possibilities. This means that, after performing an examination, even when the patient has already left the studio, we can use the received data to get additional and alternative renderings of the examined area. They are usually two and three dimensional images of examined structures, and in the case of the cardiovascular system, the images are similar to subtractive angiography. It is also possible to make three-dimensional images of the interior of organs using the light/clearance system (such as: blood vessels, stomach, intestines, trachea, bronchial tree, and even the inside of the middle ear). Such reconstructions are called multi-surface, three-dimensional or virtual endoscopy.CAT scan recommendations for orthopaedic patients:

The X-Ray diagnostic method is widely applied in medicine, mainly in the diagnosis of bone trauma. The procedure itself is straightforward as each tissue type of the body absorbs roentgen rays in different ways. The X-rays pass through soft tissue but are reflected back by the denser bone material and hence an image can be produced showing this reflection. To get the X-ray image, the radiation going through the body causes a blackening of a photographic plate according to the amount of absorption. The bone tissue demonstrates a much greater absorption capacity than the tissues surrounding it, which is visible on the film as the non-blackened area. X-ray examinations have a limited application in the diagnosis of tissues due to the fact that there is too small a difference between the absorption coefficients of these different tissues as opposed to that of the dense bone. With a view to a better depiction some shading agents are applied, called contrasts, and then a viable image of non-bone material can be createdRepeated X-ray examinations are not encouraged as too much radiation can be hazardous to health. Therefore, they are carried out exclusively on patients holding a referral issued by a doctor. For children they are limited to a minimum, and more progressive methods of diagnosis are applied, which are safer for the patient.

Magnetic resonance imaging (MRI) is a widely used and comprehensive diagnostic method. The first examinations in the world were performed in the early 1980s. Magnetic resonance imaging does not use roentgen rays (X-rays), but is based on the principle of nuclear magnetic resonance. Therefore, it is regarded as the safest method of internal diagnosis. If recommended, it can even be used to examine a foetus in utero. Magnetic resonance apparatus generates a strong magnetic field. The higher its’ intensity, the more accurate the human interior images. In clinical practice, apparatus creating 0.1 to 3.0 Tesla intensity are used. An apparatus which creates over 1.0 Tesla is called “high-field” and is used for spectroscopy, functional examinations, or the ultra-fast inspection of blood vessels and the heart.Magnetic resonance exploits properties of the nuclei of a hydrogen atom, in particular those of its protons. When put into a strong magnetic field they become magnetized, consume impulses of low frequency electromagnetic waves and send impulses during the disappearance of activity. This signal, differing in absorption depending on the kind of tissue it passes through, is processed by the computer system and converted into images which are interpreted by radiologists.We are also equipped with software for the colour shaded depiction of cartilage joints.

The digital volume tomograph is a technical innovation that allows three-dimensional recordings of the facial bones with a much lower radiation load than the standard devices Your advantages:Your Dentaprime dentist can detect bone defects and risks better than with a conventional panoramic x-rayThe condition of the jaw and the jawbone is visualized in an extremely precise way. Hence, the planning of the implantation is more reliableAn operation risk is decreasedTherapeutic chances and options become evident
