Radiology
MRI uses strong magnetic fields to align atomic nuclei (usually hydrogen protons) within body tissues, then uses a radio signal to disturb the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline states. The radio signals are collected by small antennae, called coils, placed near the area of interest. An advantage of MRI is its ability to produce images in axial, coronal, sagittal and multiple oblique planes with equal ease. MRI scans give the best soft tissue contrast of all the imaging modalities. With advances in scanning speed and spatial resolution, and improvements in computer 3D algorithms and hardware, MRI has become an important tool in musculoskeletal radiology and neuroradiology.
Siemens Healthineers
The first magnetic resonance imaging (MRI) scanner, Siemens’ MAGNETOM system, came to the market in 1983. With the aid of powerful magnetic fields, MRI scanners produce high-quality cross-sectional images without exposing patients to radiation. The sectional images displayed tissues and organs more clearly than ever before.
