In cases for which ultrasound images showing the donor's and the recipient's part of the placenta were available, echogenicity for both twins was quantified by image processing. MCA-PSV Doppler values of both fetuses were correlated to their respective placental echogenicity. Placental thickness of both twins was also measured.RESULTS: Of 756 cases with MCA-PSV measurements identified from the database, 36 (4.8%) had TAPS; of these, 23 had TAPS combined with twin-twin transfusion syndrome and 13 showed isolated TAPS. Placental echogenicity could be quantified in 28 pregnancies. Mean ± SD placental echogenicity of donor twins was significantly higher than that of recipients (138.7 ± 22.8 vs 77.9 ± 37.0; P < 0.0001). Furthermore, a significant positive correlation was found between placental echogenicity and MCA-PSV MoM (R = 0.67, P < 0.0001). Mean placental thickness of donor twins (n = 20) was significantly higher than that of recipients (49.3 mm ± 13.4 vs 25.4 mm ± 10.1; P < 0.0001).CONCLUSIONS: Echogenicity of the placental share in recipient and donor twins with TAPS correlates with MCA-PSV values. Quantification of sonographic placental echogenicity may help to determine the severity of TAPS in monochorionic twins. Copyright {\textcopyright} 2017 ISUOG. Published by John Wiley & Sons Ltd.",
