Slice-shape artifact changes with precession angle in rapid MR imaging.
One possible method of measuring T1 in rapidly acquired magnetic resonance images using variants of the FLASH technique is by the manipulation of the magnetization precession angle. It is suggested here that this method is as prone to slice-shape artifacts as many other approaches.
