MRIvizsgálat

MRIvizsgálat, or Magnetic Resonance Imaging examination, is a non-invasive medical imaging technique used to visualize internal body structures. It utilizes a strong magnetic field and radio waves to create detailed cross-sectional images of organs, soft tissues, bone, and virtually all other internal body structures. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it a safer option for certain patients and examinations.

The process typically involves the patient lying on a movable table that slides into a large, tube-shaped magnet. The magnetic field aligns the protons in the body's water molecules. Radiofrequency pulses are then applied, which temporarily knock these protons out of alignment. As the protons realign, they emit radio signals that are detected by the MRI scanner. Different tissues emit different signals, allowing the computer to construct detailed images.

MRIvizsgálat is highly effective in diagnosing a wide range of conditions, including tumors, injuries to the brain and spinal cord, abnormalities of internal organs, and musculoskeletal disorders. It can provide exceptional detail of soft tissues, which is crucial for evaluating conditions like ligament tears or herniated discs. Before the examination, patients are screened for metallic implants, as these can interfere with the magnetic field and pose a safety risk. The procedure itself is painless, though some patients may experience claustrophobia due to the confined space of the scanner. An MRIvizsgálat usually takes between 30 to 60 minutes, depending on the area being examined.
