MR Imaging

Among the many imaging methods used today, it is possible to examine any part of the body in detail thanks to the MR imaging method. MR imaging using magnetic field has an important place in the diagnosis of many diseases. Would you like to have detailed information about this imaging method, which stands out as the most important imaging method developed by technology today?

Magnetic resonance imaging is a new imaging method that has been used for the last 25 years. MRI is a painless diagnostic method that does not use potentially harmful tools such as x-rays. While the patient lies in a cylinder containing a powerful electromagnet (magnet), the procedure is performed by sending radio waves that cause hydrogen atoms in the body to release energy. The information of thousands of atoms moving with the effect of the magnet is sent to a computer and a cross-sectional image of the examined area in different axes is obtained. Radiologists obtain information about the disease by evaluating these images.

MRI examination of a single region is completed in 20 to 45 minutes. The variability of the time depends on the location of the area to be examined and the amount of information to be collected about the disease.

With MRI, it is possible to examine every organ in the body. Complex and difficult procedures such as looking inside the skull for brain tumours, examining the nerve sheaths for signs of multiple sclerosis, evaluating brain haemorrhage and joint disorders can be performed. Organs such as muscles, ligaments, blood vessels, heart, liver and kidneys can also be examined for disease. If necessary, contrast agents with minimal allergic properties are used. Since brain functions can also be evaluated with MRI, it can also be used to analyse mental disorders. The radiologist doctor who evaluates the images obtained can obtain more detailed and different information (3D images, functional images, diffusion, perfusion, biochemical examinations-spectroscopy, angiography images) by performing some additional operations via computer.

There are also patients for whom this superior imaging technology cannot be used, the most important of which are those who have metal prostheses in their body because the magnet of MRI can dislodge these metals. Among such patients, those with pacemakers are definitely not allowed to have an MRI examination. People who have had brain surgery with clips attached to their brain vessels, those with metal heart valves and those with inner ear prostheses cannot have an MRI examination except for those who are MRI compatible.

If your doctor asks you for an MRI examination, do not forget to inform him/her about the presence of such metals.

In addition, patients who cannot stay indoors can be examined under anaesthesia.

Entering the MRI room;

• – All removable metals (mobile phones, belts, hairpins, jewellery, coins, keys, dental prosthesis (iron, steel) etc. are left outside.
• – The magnet field also disrupts magnetic cards such as credit cards, CDs, tape recorders and renders them unusable.
• – Expectant mothers are taken to low tesla devices in the later months of their pregnancy. There is no obstacle during breastfeeding. However, if a contrast agent is used in MRI, the baby should be breastfed after the excretion of this agent from the body. (24 hours)

WHAT IS MR IMAGING?

Magnetic Resonance (MR) imaging is a medical technique method used to clearly distinguish anatomical structures and other structures by using radio waves into a strong magnetic field consisting of large magnets and to identify the differences between healthy and diseased tissues. MR Imaging; It is a method of examining a person’s organs and skeletal system from outside the body without any discovery in the body by surgery. With MR Imaging, different resolution images are obtained from tissues to diagnose various problems.
