Magnetic Resonance Imaging (MRI) Systems: Technical Advancements in Magnet Design, Pulse Sequences, and Clinical Applications for High-Resolution Soft-Tissue Diagnosis
Magnetic Resonance Imaging (MRI) systems utilize powerful magnetic fields and radio waves, not ionizing radiation, to create incredibly detailed cross-sectional images of the body’s soft tissues, making it a cornerstone of modern diagnostic medicine. The technology is particularly valuable for imaging the brain, spinal cord, and joints, where its superior soft tissue contrast surpasses that of CT scans. Key technological components include the main magnet, gradient coils, and a sophisticated RF coil system for transmitting and receiving signals.
