摘要: OBJECTIVE. The purpose of our study was to evaluate image quality in a 3D spoiled gradient-recalled echo (SPGR) sequence that modified incorporate respiratory navigation limit the deleterious effects motion and compare it with conventional scanning during breath-holding free breathing.CONCLUSION. Respiratory SPGR sequences is technically feasible, modestly improved over breathing acquisitions using sequences. This may represent promising imaging alternative for patients who cannot hold their breath.
