The impact of field strength on image quality in MRI

WebHigh Field MRI utilizes a cylindrical tube in which the magnet is enclosed. Patients are placed in the unit lying down, either head first or feet first. Since this configuration produces optimum magnetic field strength, the signal and images produced are of the highest quality. High Field MRI exams usually take 20 – 30 minutes. 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.
