MAGNETIC RESONANCE (MR)

MR imaging is the most advanced medical imaging method that allows detailed imaging of all tissues and organs of the body without the use of radiation.

The basic principle of operation is that radio waves are sent to the human body in a magnetic field and the signals received in response to this are converted into images with the help of a computer.

For examination, the patient is placed in a wide tunnel-like open-ended device. The examination does not cause any pain. Magnetic field has no known harm to tissues.

The physical foundations of MR technology were found in the 19th century. It took another century to be used for health imaging purposes.

It became widespread and used in the late 1980s. The widespread use of clinical use has led to rapid developments in MR technology. Studies, mostly aimed at improving image quality in the 1990s, are increasing in the 2000s, aiming at making patients more comfortable during this examination.

It is the primary and indispensable imaging method in many branches of medicine. In addition, some operations that could not be done before due to the magnetic field have become possible by producing suitable materials. One of these, MR-guided breast biopsy or wire marking is also applied in our center.

SIGNA™ Pioneer MR

Revolution* CT

 

SIGNA Pionner through multiple images with different degrees of contrast in a single MR scan image can be created at the same time. More than one during shooting Scanning with software solutions provided by GE, as well as printing the image obtained during the different contrast afterwards. can be processed to have the values.

Signa Pioneer it time, manpower and time of use of the machine. increases efficiency by saving. In this way, each conventional methods, in which contrast is obtained separately, are only One third of them can be completed on time. That's saved time, possibility to take at least one extra shot per hour provides.

SIGNA Pioneer scanning In addition to the increase in speed, it does not require anesthesia. especially for patients in risk groups such as children and the elderly it is a revolution. Scanning speed, also closed area sedentary during crawling, such as those with a fear, or children It also offers comfort for patients who may be difficult to stop, preventing distorted images as a result of movement, does not need to be repeated.

FREQUENTLY ASKED QUESTIONS

What are the usage areas of MR?
It is the preferred examination method for the diagnosis of many parts of the body and diseases that may occur in these areas. In general, it distinguishes diseased and healthy tissues from each other. The most common areas of use are brain, neck, spinal cord, all joints, abdominal organs, breast, blood vessels and heart imaging.

Is MR safe?
The MR device can suddenly move any ferromagnetic objects near it. This can cause harm to people near the device. Therefore, before the examination, the patient is asked to remove metallic objects. The magnetic field can also attract ferrous metals inside the body. It may cause it to overheat. It is important that patients who carry such metals in their bodies inform the radiology technician and doctor before the examination. The magnetic field may disturb hearing aids, pacemakers, insulin pumps, and some other medical devices. In patients with a foreign body after a gunshot injury, the object may cause displacement and heating. Some MR examinations require the use of a contrast agent called gadolinium. However, this contrast medium does not contain iodine like other radiological contrast agents and allergic reaction is extremely rare. It is recommended that patients with advanced kidney disease inform their radiology technician and doctor beforehand.

Substances that can harm your health during MR examination:
Pacemaker or implantable defibrillator Catheter Aneurysm clip in the head External medication pump (pumps insulin or pain relieving medication) Cochlear (inner ear) implant Neurostimulation system

Things to remove before entering the MR room:
Bags, purses, credit cards, magnetic stripe cards. Pagers or cell phone. Hearing aids Metal jewelry, watches Pen, paper clips, keys. Hairpins. Metallic clothing.

Objects that do not cause damage during MRI but cause a decrease in image quality when close to the examined area:
Metallic materials used for all kinds of orthopedic purposes. Piercing Tattoo Eye make-up. Dental fillings.

What are the preliminary preparations required for MR examination?
MR examinations outside the abdominal area do not require any preparation. Abdominal examinations usually require fasting. Before the examination, the patient is warned once more by the radiology technician about the objects that may pose a health risk inside or outside the body.

Claustrophobia:
Disorders related to claustrophobia can be observed during MRI in 5% of the patients. This ratio has decreased due to the shorter tunnel in new devices compared to the old. Claustrophobia can be reduced with sedative drugs before the procedure. In addition, since magnetic resonance has no known harm, it is possible for the patient to be in the MRI room with his friend.

Pregnancy MR:
Although there is no known harm of MRI in pregnant patients, in cases where pregnancy or pregnancy is suspected, the radiology technician or doctor should be warned beforehand. MRI is recommended during pregnancy only in important cases. Examination can be done during breastfeeding. However, if gadolinium was used during the examination, it is recommended to stop breastfeeding for a day.
