WebHigh-Field Strength Magnetic Resonance Imaging High (3 T) and ultra-high (7 T) MRI scanners greatly improve sensitivity for detecting T2 and Gd-enhancing lesions. Cerebral lesion volume also increases with higher field strength ( Bachmann et al., 2006; Sicotte et al., 2003 ), and cortical lesions are easier to detect.
WebThe main characteristics of a magnet are: Type (superconducting or resistive electromagnets, permanent magnets). Strength of the field produced, measured in Tesla (T). In current clinical practice, this varies from 0.2 to 3.0 T. In research, magnets with strengths of 7 T or even 11 T and over are used.
