[Display omitted] •Effects of using SPF, PPF, and radial scan methods on image quality were compared.•Radial scan is a series of B-scans separated at regular angular intervals.•Radial scan method has lower image quality loss and shorter imaging time than others.•Radial scan reduces the imaging time with no changes in effective slice thickness.•Radial scan method causes minimal loss in in-plane resolution. This study aimed to investigate the effect of using slice partial Fourier (SPF), phase partial Fourier (PPF), and radial scan (Elliptical scanning) methods on image quality. Changes in signal-to-noise ratio (SNR), effective slice thickness, and in-plane resolution were measured in 3D-gradient echo when SPF, PPF, and radial scan were used. Effective slice thickness increased and SNR increased when SPF was used; in-plane resolution decreased and SNR decreased when PPF was used; effective slice thickness did not change, in-plane resolution decreased, and SNR increased when the radial scan method was used. The radial scan method reduces image quality and imaging time compared to those in the SPF and PPF methods.
