Quality control of prenatal ultrasound. A role for biometry

摘要

Because of an increasing demand for limited health care resources as well as an increasing impact of legal aspects in ultrasound practice, it has become necessary to ensure that screening procedures are cost-effective and clinically effective and to develop systems that could help sonographists in certifying their practice. Based on the literature, various approaches for quality control are reviewed. Special emphasis is put on the use of fetal biometry and statistical tools to develop quality control systems based on both qualitative and quantitative approach. Besides their potentials for audit and quality control, such tools could also be useful during the process of training.
