Magnetic resonance imaging

Magnetic resonance imaging

Magnetic resonance imaging” (MRI) is an advanced medical imaging technique that uses magnetic fields and radio waves to produce detailed images of various parts of the body, including soft tissues, joints, the brain, the spinal cord, and many other internal organs.

During a magnetic resonance imaging scan, the patient is positioned inside a strong magnetic field generated by a superconducting magnet.

The hydrogen atoms in the patient’s body are aligned with the magnetic field and are then exposed to pulses of radio waves at specific frequencies. These pulses cause the hydrogen atoms to emit signals that are detected by a detection coil, generating data that is then processed by a computer to produce three-dimensional images of the body.

How is magnetic resonance imaging performed?

  • Patient preparation: Before the examination, the patient may be asked to remove any metallic objects, such as jewelry, watches, dentures, and medical devices. It is important to inform the medical staff of any prior surgeries, implants, or implanted medical devices, as they may interfere with the MRI scan.
  • Patient positioning: The patient is positioned on the movable bed of the MRI machine and pushed into the magnet. The radiologic technologist ensures that the patient is comfortable and that the body part to be examined is positioned correctly inside the MRI machine.
  • MRI scan: During the scan, the MRI magnet creates a strong magnetic field around the patient, and a series of radiofrequency pulses are sent through the body. These pulses cause hydrogen atoms in the body tissues to produce signals, which are detected by a detection coil placed around the body part being examined. These signals are then processed by a computer to produce detailed images of the internal structures.
  • Examination duration: The duration of an MRI exam can vary depending on the type of scan and the part of the body being examined, but it typically lasts from 20 to 60 minutes.
  • Images and interpretation: Once the scan is completed, the MRI images are displayed on a monitor and interpreted by a specialized radiologist. The radiologist evaluates the images to diagnose any medical conditions and sends a report to the attending physician.

Useful information

Magnetic resonance imaging is used to diagnose a wide range of medical conditions, including traumatic injuries, vascular diseases, tumors, structural abnormalities, neurological disorders, and much more. The high-resolution images produced by magnetic resonance imaging allow doctors to accurately visualize anatomical structures and identify any abnormalities or pathological changes.

How to prepare?
Preparation for a magnetic resonance imaging (MRI) exam mainly depends on the part of the body being examined and specific instructions from the medical center. However, here are some general guidelines for preparing for an MRI exam:

  1. Communicate any medical conditions or allergies.
  2. Follow instructions regarding diet and fasting.
  3. Remove metallic objects.
  4. Dress appropriately.
  5. Communicate any medications being taken.
  6. Follow the instructions of the medical staff.
