Angle of fetal head progression measured using transperineal ultrasound as a predictive factor of vacuum extraction failure.
To evaluate the predictive value of angle of progression (AoP) of the fetal head for a failed vacuum delivery. ⋯ AoP is a predictive factor of failed vacuum extraction, especially among nulliparous women whose risk of failure is high. AoP measurement may help in choosing between forceps and vacuum extraction. Copyright © 2015 ISUOG. Published by John Wiley & Sons Ltd.

Interpreting the real-time dynamic 'sliding sign' and predicting pouch of Douglas obliteration: an interobserver, intraobserver, diagnostic-accuracy and learning-curve study.
To determine inter- and intraobserver agreement, diagnostic accuracy and the learning curve required for interpreting the 'sliding sign' and predicting pouch of Douglas (POD) obliteration. ⋯ Performance of a minimum number of gynecological ultrasound examinations is necessary for interpreting offline videos of the real-time dynamic sliding sign and predicting POD obliteration. Non-specialist observers with prior experience of 200 or more gynecological scans were more consistent in interpreting the sliding sign at the retrocervix vs PUF. Copyright © 2015 ISUOG.

To evaluate the diagnostic yield of postmortem magnetic resonance imaging (PM-MRI) compared with conventional autopsy in fetuses of early gestational age and low body weight. ⋯ PM-MRI is highly likely to provide adequate diagnostic images for fetuses with a body weight > 500 g. Below this weight, the diagnostic yield of standard 1.5-T PM-MRI decreases significantly. These data should help inform parents and clinicians on the suitability of performing PM-MRI in fetuses with low body weight. Copyright © 2015 ISUOG. Published by John Wiley & Sons Ltd.
