Ultrasound assessment of the fetal biophysical profile: what does an radiologist need to know?
Proposed by Frank Manning about 26 years ago, fetal biophysical profile has been incorporated to the propaedeutics of non-invasive fetal well being assessment in high-risk gestations. Despite the existence of other methods for assessing fetal vitality, as Doppler flowmetry, the biophysical profile continues to be important in estimating the risk of hypoxia and perinatal morbimortality for those fetuses. In the present article, the authors review the regulatory mechanisms of fetal biophysical activities, as well as physiological and pathological factors that interfere with them. The main objective of the study is to discuss the present and important aspects of the method, and the practical applications and interpretation of its findings, in order to help radiologists improve their knowledge in this specific area of fetal ultrasonography.
