The importance of the cerebroplacental ratio in the evaluation of fetal well-being in SGA and AGA fetuses  Greggory R. DeVore, MD  American Journal of Obstetrics & Gynecology  Volume 213, Issue 1, Pages 5-15 (July 2015) DOI: 10.1016/j.ajog.2015.05.024 Copyright © 2015 Elsevier Inc. Terms and Conditions

Figure 1 Recordings from a fetus whose mother was a late registrant for prenatal care These recordings are from a fetus whose mother was a late registrant for prenatal care. There was a 14 day difference between the menstrual age and the mean ultrasound gestational age. The abnormal cerebroplacental ratio suggested that fetal growth restriction was the correct diagnosis. How to acquire the images and make the measurements is illustrated in the Video available at ajog.org. DeVore. Cerebroplacental ratio in fetal well-being in SGA and AGA fetuses. Am J Obstet Gynecol 2015. American Journal of Obstetrics & Gynecology 2015 213, 5-15DOI: (10.1016/j.ajog.2015.05.024) Copyright © 2015 Elsevier Inc. Terms and Conditions

Figure 2 Fetus with several abnormalities This is an example of a fetus with A, a high but normal PI of the umbilical artery, B, low but normal PI of the middle cerebral artery, and C, an abnormal cerebroplacental ratio below the fifth centile (red). Each graph illustrates the raw data for the mean (dots) and 95th and fifth centiles (solid lines). The dotted line is the mean of the regression line. The reference ranges are from a study by Baschat and Gembruch.9 CPR, abnormal cerebroplacental ratio. DeVore. Cerebroplacental ratio in fetal well-being in SGA and AGA fetuses.

Figure 3 Fetus with other abnormalities This is an example of a fetus with A, a normal PI of the umbilical artery, B, abnormal low PI of the middle cerebral artery, and C, an abnormal CPR below the fifth centile (red). Each graph illustrates the raw data for the mean (dots) and 95th and fifth centiles (solid lines). The dotted line is the mean of the regression line. The reference ranges are from a study by Baschat and Gembruch.9 CPR, cerebroplacental ratio; SGA, small for gestational age; PI, pulsatility index. DeVore.

Figure 4 Fetus with an elevated PI of the UA, low PI of the MCA, and an abnormal CPR This is an example of a fetus with A, an elevated PI of the umbilical artery, B, low PI of the middle cerebral artery, and C, an abnormal CPR below the fifth centile (red). Each graph illustrates the raw data for the mean (dots) and 95th and fifth centiles (solid lines). The dotted line is the mean of the regression line. The reference ranges are from a study by Baschat and Gembruch.9 CPR, cerebroplacental ratio; MCA, middle cerebral artery; PI, pulsatility index; SGA, small for gestational age; UA, umbilical artery.
