It is a medical technique used within the strong magnetic field created with large magnets, using radio waves to clearly distinguish certain anatomical structures from other structures, to identify the differences between healthy and diseased tissues. It is one of the most impressive and most harmless imaging methods. No pain is encountered after MR. There is no obligation to use an allergy-causing drug before or during imaging.
In which cases is it used?
- In migraines and headaches,
- In neurological conditions,
- In patients with suspected brain tumor,
- In patients with epileptic seizures,
- In patients with eye, ear, jaw joint problems,
- Spinal problems, disc slips and disc hernias,
- Evaluation of joints and ligaments such as shoulders, knees,
- Sports injuries,
- In heart diseases,
- Chest and abdominal viscera diseases,
- Bone structure disorders
How to do MRI?
The patient has to remove the materials that will be affected by the magnetic field such as clock, credit card, metal goods before entering the MR room. The imaging process takes between 15-45 minutes. During this period, the patient is asked to remain motionless to avoid disruption in imaging.
* Diffusion Dominated MR
Images resulting from the molecular movements of water in the tissue are obtained. It is useful in detecting the character of tumors and in the diagnosis of acute stroke.
* Perfusion Dominated MR (PA – MR)
It is an MR type that measures the blood supply of the brain using contrast media. It is used in stroke, intracranial tumors, epilepsy, dementia, cognitive disorders and non-invasive evaluation of normal physiological changes.
* Functional MR (fMR)
It maps brain activity and measures metabolic changes in the brain. It is a valuable screening method in the evaluation of surgical risk and planning of the operation. It helps to identify important centers, language and motion control areas in the brain.
* Brain Order
It is used to examine the intersections of the brain vessels called aneurysm, eye and inner ear diseases, Multiple Sclerosis (MS) disease, spinal cord injuries, dementia, stroke, central nervous system tumors and brain damage caused by trauma.
* Magnetic Resonance Spectroscopy (MRS)
It is an imaging method that can display metabolite changes at the cellular level by analyzing particles such as hydrogen ions or protons.
* MR Angiography
It is an imaging method used to evaluate blood vessels, detect abnormalities or diagnose atherosclerotic vascular disease.
