Quality assurance (QA) and safety are important components of obstetric imaging. Quality involves accreditation of the imaging unit as well as equipment inspection for function and image quality. The personnel working in the unit must demonstrate qualifications to perform, evaluate, and interpret the studies. Standardizing the required elements of the examination helps assure that a quality examination has been performed. QA and safety as well as physician requirements and equipment QA programs in ultrasound, computed tomography, and magnetic resonance will be discussed with an in depth look at ultrasound due to its more frequent use in pregnancy.
