Objectives: After studying the article entitled “Prenatal Diagnosis of Placental Invasion: A Systematic Review and Meta-analysis on Accuracy of Ultrasonography and MRI in Diagnosis of Placental Invasion,” you will be able to:
Define placenta accreta, placenta increta, and placenta percreta
Compare the diagnostic accuracy of sonography and MRI to diagnose placental invasion
Understand the importance of diagnosing placental invasion prenatally
What is the estimated prevalence of placental adherence defects? 1:250 1:500 1:2500 1:30,000
Which database was used to locate the latest or current systematic reviews? MEDLINE EMBASETM LILACS PROSPERO
What DOR value specifies that the test has no discriminative power? 0 1 2 3
According to Figure 1, how many studies were included in the final review? 7 17 299 1155
What was the sensitivity of MRI for detecting placental invasion? 89% 95% 97% 99%
What was the sensitivity of ultrasound for detecting placental invasion? 66% 73% 89% 95%
What was the combined sensitivity for the prospective studies for ultrasound? 0.75% 0.81% 0.92% 0.95%
Placental invasion into the myometrium but not beyond is termed? Placenta accreta Placenta vera Placenta increta Placenta percreta
Based on the systematic review and meta-analysis, what was the specificity of ultrasound in detecting placental invasion? 66% 73% 84% 89%
According to the study by Mar et al., what was the most sensitive marker with the highest positive predictive value for placental accreta? Loss of bladder wall echogenicity Loss of retroplacental clear space Increased intraplacental vascularity Placental lacunae
