Magnetic Resonance Imaging (MRI) systems are categorized into two primary configurations: traditional cylindrical systems and those with a more open structure. Cylindrical systems offer a high degree of magnetic field homogeneity, leading to superior image quality and faster scan times. Open configurations, while offering greater patient comfort and reduced claustrophobia, may produce images with slightly lower resolution or require longer scan durations due to variations in magnetic field strength.
The choice between these system types depends on various factors, including patient characteristics (e.g., body size, anxiety level), specific diagnostic needs, and the imaging center’s resources. Open MRI proved a significant advancement for patients who experience claustrophobia or have larger body habitus, making the procedure more accessible. While the closed, cylindrical design remains the gold standard for many diagnostic applications, open designs continue to evolve, narrowing the gap in image quality and scan times.
