Magnetic Resonance (MRI)

Magnetic Resonance (MRI)

The Medical Centers provide patients with 6 state-of-the-art MRI machines.

Magnetic Resonance (MRI) is a state-of-the-art imaging technique that uses a strong magnetic field and radio waves to provide high-resolution images of selected regions of the human body, providing anatomical detail and the relevant pathology or lesion with accuracy and precision.

The technique does not use ionizing radiation (X-rays) and is considered safe for the patient, especially for people who require multiple serial examinations to monitor their conditions. The equipment used in our centers is a new generation, offering high-resolution images.

Our equipment is considered top equipment in the class of nuclear magnetic resonance devices – being equipped with the latest investigative software, which allows high-fidelity examination of all anatomical regions of the body in an extremely short time. All organs can be studied by MRI, but it is of choice in neurological/neurosurgical pathology (central nervous system, spine), gynecological/urological (uterus, ovaries, prostate), musculoskeletal (knees, coxofemoral joints, etc.), but also in pathology vascular through the non-invasive visualization (with or without contrast substance) of the circulatory tree.

Compared to the CT examination, it has the advantage of the possibility of a direct multiplanar acquisition, but also of three-dimensional reconstructions that allow the appreciation of complex structures or lesions.

The GE Signa Explorer system, through the READY Brain option, offers the highest quality images in neurological studies. Regarding the spine, the possibility of scanning an extended area and the movement correction techniques allow the acquisition of clear images, resistant to artifacts caused by the patient’s movement and the flow of cerebrospinal fluid.

 The equipment is equipped with IDEAL software, created especially for scanning difficult regions, such as the neck and spine, where classic scanning techniques fail due to inhomogeneous magnetic fields.

SIGNA Creator

Built with the DNA of SIGNA, the pioneer of magnetic resonance systems, SIGNA Creator (Riverside 1 and Riverside 2 clinics) offers exceptional image quality and ensures detailed clinical information, using advanced software such as motion artifact correction.

An MRI scan is a painless technique that has the advantage of avoiding the use of X-rays and radiation exposure. There are no known side effects of an MRI scan. The benefits of an MRI scan refer to the accuracy in detecting structural, compositional, and functional abnormalities of the body and to the fact that it can be repeated as often as needed without contraindications.

Magnetic Resonance (MRI) imaging allows the visualization of the smallest details in the human body, without the use of X-rays.
MRI advantages:

  • It does not pose a danger to the human body;
  • It detects very small lesions – 1mm, allowing a highly accurate diagnosis.
  • The equipment used in our centers is top in the class of nuclear magnetic resonance devices – being equipped with the latest investigative software, which allows high-fidelity examination of all anatomical regions of the body in an extremely short time.

Information about magnetic resonance (MRI)

The MRI exam does not require special preparation. Normally, a special diet is not necessary before the investigation. You can carry out your usual activity and you are advised to take the current medication prescribed by your doctor. For the abdominal MRI, you may be asked not to eat 2-3 hours before the examination.

Before the examination, you are asked to fill out a questionnaire with information related to the reason for the examination and possible contraindications for MRI. You may be asked for recent blood tests, especially urea and creatinine, indicators of kidney function; depending on their values, the injection of paramagnetic contrast substance iv is allowed or not. Metal objects (watches, keys, coins, jewelry) are strongly attracted to the magnet, they can injure you and are prohibited in the MRI examination room. Their presence can compromise the quality of the images. The MRI machine can damage any card with a magnetic strip such as a credit card, or electronic or mechanical devices (mobile phone, watch, etc.). Jewelry can conduct electromagnetic waves and heat up. Additionally, please don’t wear clothes with metal inserts. Please do not wear clothes with metallic details.

The most important information is related to absolute or relative contraindications for the examination.

  • People with pacemakers, artificial limbs, metal rods or any other kind of metal objects fixed in the body (shrapnel, etc., e.g. eyepieces), heart valves, intracranial devices (clips on aneurysms), magnetic pumps for chemotherapy, etc., cannot perform an MRI;
  • some metal prostheses/stents or implants may be MRI compatible, but it is necessary for the doctor requesting the MRI examination to specify this;
  • inform the doctor if you have undergone a recent surgical intervention;
  • intrauterine devices installed 10-15 years ago are not MRI-compatible;
  • inform the doctor if you have allergies to medicines or other substances; for MRI, it is not an absolute contraindication to the administration of contrast, and the administration of an anti-allergic beforehand reduces the risk of adverse reactions;
  • claustrophobia (fear of narrow spaces) is a relative contraindication; our staff will be at your disposal for familiarization with the device and overcoming it;
  • inform the doctor if you suffer from diabetes or renal dysfunction/insufficiency (these may contraindicate the administration of contrast).

The patient is seated on a mobile table that is to be introduced into an examination field, open at both ends. The ”antenna” used to receive a signal from your body is placed around the region of interest. Then the table is introduced into the examination field, ventilated, with its light source, so that the region of interest is located in the center of the magnet.

You will be asked to stay still/collaborate during the examination to obtain the best possible quality images, depending on the examination, while being able to take the first breathing commands. All MRI machines produce noise during the examination; this may create slight discomfort, but it is a normal technical aspect. During the examination, an operating physician constantly monitors you. You will receive an emergency rubber pump that you can press in case of emergency so that the examination can be stopped at any time at your request.

  • preparing for the exam and completing the questionnaire can take about 15 minutes;
  • a usual MRI investigation lasts 20-40 minutes for one part of the body, but can be extended if necessary (eg: administration of contrast substance) up to an hour;
  • it is not always possible to anticipate the need for intravenous contrast administration; this decision can only be taken by the specialist radiologist during the investigation, depending on the revealed lesions; the contrast allows additional characterization of the lesion and a more specific diagnosis.

IMPORTANT:

  • you can continue your daily activities immediately after the examination; the MRI investigation is painless (completely atraumatic).
  • paramagnetic contrast substance administered intravenously can very rarely have adverse effects;
  • these are much rarer than for the iodinated contrast used in computed tomography;
  • inform the doctor if you are pregnant; the MRI exam can sometimes be performed in the 2nd or 3rd trimester of pregnancy in special situations;
  • contrast administration is not recommended during pregnancy or breastfeeding.
