A 1.5T MRI (Magnetic Resonance Imaging) is a type of MRI scanner with a magnetic field strength of 1.5 Tesla. This mid-range strength offers high-quality images for diagnosing a wide range of conditions, including neurological, musculoskeletal, and cardiovascular issues. It provides excellent resolution and is commonly used in hospitals for routine imaging due to its balance of performance and cost.

A 3T MRI (Magnetic Resonance Imaging) scanner operates with a magnetic field strength of 3 Tesla, offering higher resolution and more detailed images than a 1.5T MRI. This increased strength is ideal for imaging soft tissues, brain, spine, and joint conditions. 3T MRI systems provide faster scans and improved sensitivity, making them suitable for advanced diagnostics and research. However, they may be more expensive and less widely available compared to 1.5T systems.
