MRItechnologie
MRI technology uses a strong static magnetic field, gradient fields, and radiofrequency pulses to generate detailed images of internal structures. Hydrogen nuclei align with the magnetic field and, when perturbed by RF pulses, emit signals that are spatially encoded and reconstructed into cross-sectional images by a computer. The method provides high soft-tissue contrast without ionizing radiation, making it especially valuable for the brain, spine, joints, and many abdominal organs.
Key components are a superconducting magnet, gradient coils, RF transmit/receive coils, and a computing system. Field
Advantages include excellent soft-tissue detail and no ionizing radiation; limitations include longer scan times, sensitivity to
Applications span neurology and neurosurgery, musculoskeletal imaging, oncology, cardiology, and abdominal imaging. The technology originated in
