MRI-Magnetic Resonance Imaging
MRI Magnetic resonance is a diagnostic procedure in which no X-rays are applied, but is based on the resonance of hydrogen ions in a strong magnetic field, signaling occurs, which by computer programs are converted into an image. In this way the resulting image allows a high differentiation of the soft tissue structures and the blood vessels significantly better than the CT. It is painless and without any radiation and harmful effects for patients (as opposed to CT), so the examination can be repeated several times without any harmful consequences.
For certain shoots, a contrast is also required to better visualize the pathological process and provide more accurate diagnosis. The modern 1.5T appliances, as well as our facility (Figure 1, Siemens Essenza at our facility), combined with the latest powerful software, enables immeasurable shooting even in situations where it was not possible before
MRI with anesthesia
Where needed, usually for children under 5 years of age and restless or claustrophobic patients, short anesthesia can also be given to obtain high quality recordings for diagnosis. Anesthesia is performed in co-operation and controlled by anesthesiologists.
Important note for recording!
Before the recording it is necessary to inform a doctor or a radiology engineer on:
"pacemaker" or other built-in electronic devices because it is often impossible to record MRs due to the interference in the operation of these devices in the magnetic field (a new generation of pacemakers, stents can go to MRI recording)
metal bodies in the body (marks, debris, buckles after surgery on blood vessels, metal plates ...)
Pregnancy: no detrimental effect of the MR imaging itself has been demonstrated, the contrast metal gadolinium passes through the placenta to the fruit and there is a doubt that it can damage it. Therefore, women who are pregnant should note this before taking a picture.
breastfeeding is not a contraindication for MR examination, but if contrast is used, it is advised to stop breastfeeding in the next 24 hours.
There must be no items of magnetic material (credit cards, cell phones, keys, etc.) in the room with the appliance.
dental implants and seals do not represent a contraindication for this review!
There are two basic types of apparatus for magnetic resonance imaging. Open-end use permanent magnets, and enclosed are used to generate a magnetic field that is powered by electricity. Closed devices are stronger, mostly from 0.5 to 3 T (Tesla), and their views last shorter.
According to the magnitude of the magnetic field, the MR recording devices are divided into:
low field strength devices - up to 0.5 T
medium field strength devices - 0.5 T to 1 T
high field strength devices - 1 T and above (1.5 T, 2 T, 3 T, 7 T, ...)
The quality of the display is the proproximate magnitude of the magnetic field, but this is not the only factor-image quality to a large extent dependent on the applied image processing software and the knowledge of the engineer that is being recorded.
Magnetic resonance imparts exceptionally precise analysis of muscular structures such as brain, spinal cord, tibial, small, lung, lungs that were previously unavailable, as well as a real anatomical representation of a particular region and localization of the lesion or foci in it as any other technique display
Unlike CT, there is no radiation (especially significant in younger people, pregnant women, certain patients) and has excellent contraction resolution for certain tissue damage, tumors, and so it is important that this process can be seen in a phase when small dimensions , and other diagnostic procedures (Above, CT) can not be recognized.
It shows the condition of the rectum, rectosigmoid part of the column, vagina, uterus, ovary, wavelength, bladder, prostate, seminal vesicle, regional lymph nodes. MRCP This review shows gallbladder, gall bladder and successfully replaces the classic, invasive ERCP review. A precise insight into the condition of the gall bladder and the gall bladder is obtained and successfully detects the existence of calculus and other damage of up to 3 mm.
It is a method of visualization of large intestine (if necessary and thin) magnetic resonance imaging, which requires strong field devices and the latest image processing software, and is an elegant and comfy alternative to classical colonoscopy or MSCT colonography as an excellent screening method, completely painless, without inflammation , without removal, without discomfort, without radiation. The preparation is like for a classic colosseum, and for recording only, it is not necessary to download, inflow, ...
MRI spine, in diagnosing neck and back pain
for pain in the neck and back, MRI is the best diagnostic method!
They see very well:
- spinal column anomalies
- knee injuries
- inflammatory processes in spasms and spinal cord
- hernias of the disc
- tumors of swelling, nerve and spinal cord
- diseases involving the bone marrow
- cysts (arahnoid, perineural, dermoid, cystic, interstitial joints).
MRI in diagnosis of headaches
On the other hand, magnetic resonance imaging is an indispensable tool for diagnosing secondary headaches, more precisely the ailments that cause them. Causes of secondary headaches are, therefore, other, sometimes serious illnesses, damage or tumors.
MRI examination can also diagnose headaches caused by contact of blood vessels with cranial nerves. This is most often the case with neuralgia of the fifth cerebral nerve (trigeminal neuralgia).
MRI of the heart and blood vessels
MRI of the heart is an excellent method for diagnosing some diseases and heart problems (Figure 1) and blood vessels (Figure 2.3), primarily in:
- heart defects
- trumpet, heart tumor
- myocarditis diagnosis
- mybilinous myocardial analysis, contractility, scarring changes,
- perfusion of cardiac muscle of the palpitations disease
- aortic diseases
- neck and head artery blood vessels
- diseases of the peripheral arteries
- vein venography diseases
- diseases, primarily arthritis (renal)

MRI Breast is an excellent breast imaging method that combines breast disease diagnosis, including ultrasound, mammography, elastography, FNAC, core biopsy
MRI of the joints, bones, muscles, musculoskeletal structures
The method is precise and for now, above all diagnostic methods, specifically for displaying ligaments within the joints.
