How is magnetic field strength measured in MRI?

Magnetic field strength in MRI is measured in Tesla (T). The Tesla is a unit of measurement in the International System of Units (SI) that quantifies the strength of a magnetic field. Magnetic resonance imaging relies on powerful magnets to create a strong magnetic field, which is essential for aligning the protons in the body’s hydrogen atoms. The higher the field strength measured in Teslas, the greater the sensitivity and resolution of the imaging, allowing for clearer and more precise images. MRI systems typically operate at field strengths ranging from 1.5 T to 3.0 T, with some advanced systems even reaching higher levels. This measurement is critical for understanding how effectively the MRI system can capture detailed images of the internal structures of the body.
