WebDec 21, 2024 · As such, Gibbs artifact in the sagittal plane might be less apparent on axial imaging, whereas true cord pathologies will persist . Awareness of Gibbs artifact and reviewing both sagittal and axial imaging enables pain physicians to distinguish between DCM and Gibbs artifact and ensure safe conduct of CILESIs. WebOct 10, 2024 · A data truncation artifact may occur when the interface between high and low signal intensities is encountered in one imaging plane. The 2D-FT techniques transform the MR signal to spatial intensity image data with frequency and phase information encoding each axis in the plane of the scan. This artifact is found in both frequency and phase …
