The sensitivity of sonography to predict accreta has been reported as higher than 90%. However, most studies are from single expert investigators. Our objective was to analyze interobserver variability of sonography for prediction of placenta accreta.

To evaluate the accuracy of ultrasound in the diagnosis of placenta accreta and its variants, and to assess the impact of prenatal diagnosis in our population.

Placenta Accreta Spectrum: Prenatal Diagnosis and Management.

Imaging of Placenta Accreta Spectrum

The goal of this article is to discuss the common clinical presentation and risk factors for placenta accreta spectrum, and to review in detail the ultrasound features/markers of PAS in each trimester.

Introducing an efficient model for the prediction of placenta accreta spectrum using the MCP regression approach based on sonography indexes: how efficient is sonography in diagnosing accreta?

Using the introduced model based on three factors of abnormal lacuna structures, bladder wall interruption and utero-vesical vascularity, 100% of all cases of PASs are diagnosable.

Sonographic Detection of Placenta Accreta in The Second and third Trimesters of Pregnancy

US still the most sensitive and frequently utilized scanning modality for the placental accreta diagnosing as it is precise, cheap, and noninvasive and save time.

Morbidly adherent placenta: the need for standardization

Problems with lack of uniformity and the need for standardized nomenclature for the diagnosis, treatment and research ofMorbidly adherent placenta are identified and potential solutions are suggested.

Placenta Accreta: A Spectrum of Predictable Risk, Diagnosis, and Morbidity.

As the depth of invasion decreases, clinical risk factors and sonographic evaluation are less reliable in the antenatal prediction of placenta accreta, and the potential for unanticipated morbidity underscores the need for improved diagnostic tools for placentasaccreta spectrum.

Value of Crystal Vue technique in detecting the placenta accreta spectrum located in c-section scar area.

Combining the Crystal Vue technique with 2D ultrasound can improve the diagnostic accuracy of ultrasound for detecting all types of placenta accreta spectrum located in C-section scar area.

Utility of diffusion-weighted MR imaging in the diagnosis of placenta accreta spectrum abnormality

With the current imaging technique, addition of DWI sequence to the traditional T2W images cannot be shown to significantly increase the accuracy or reader confidence for diagnosis of placenta accreta spectrum abnormality, however, DWI does improve identification of abnormalities in the placental–myometrial interface.



Evaluation of sonographic diagnostic criteria for placenta accreta

To compare the diagnostic value of reported sonographic criteria for placenta accreta and to develop a composite score system for antenatal evaluation.

Objective  The aim of this study was to evaluate the efficacy of transabdominal color Doppler ultrasound in diagnosing placenta previa accreta.

Antenatal diagnosis of placenta previa accreta in patients with previous cesarean scar

Aim:  To determine the accuracy of transabdominal and transvaginal gray‐scale and color Doppler in diagnosing placenta previa accreta in patients with previous cesarean sections.

The Sonographic Appearance of Placenta Accreta

In this study, findings in six cases are reported, four of which were accurately diagnosed sonographically as placenta accreta, one which resulted in a false-positive diagnosis, and one which results in afalse-negative diagnosis.

Positive sonographic results suggest presence of numerous intraplacental vascular lacunae appears to be an additional risk criterion for placenta accreta, separate from the other criteria listed above.

Accuracy of Ultrasonography and Magnetic Resonance Imaging in the Diagnosis of Placenta Accreta

Ultrasound imaging is the mainstay of screening for placenta accreta and MRI appears to be complementary to ultrasonography, especially when there are few ultrasound signs.

Optimal management strategies for placenta accreta

To determine which interventions for managing placenta accreta were associated with reduced maternal morbidity, a large number of patients were randomly assigned to receive either a vaginal or laparoscopic Caesarean section.
