Trimester‐specific diagnostic accuracy of ultrasound for detection of placenta accreta spectrum: systematic review and meta‐analysis

This is the authors' abstract. We don't add key points for this paper.

First-trimester ultrasound examination has similar accuracy to second- and third-trimester ultrasound examinations for the diagnosis of PAS. Routine first-trimester ultrasound screening for patients at high risk of PAS may improve detection rates and allow earlier referral to tertiary care centers for pregnancy management.
