Aims and objectives

Identify anomalies of placental implantation, including the various forms of placenta previa and placenta accreta. Discuss the added value of crosssectional imaging in the evaluation of invasive placental processes, including placenta accreta and gestational trophoblastic disease.

Methods and materials

Clinical series descriptive study with a retrospective examination ofwomens with placental abnormality.US were performed in all patientsand Magnetic resonance imaging (MRI) in 5 cases. Of our 20 womens, placenta previawas found in 6 cases,placenta accreta in 5 cases, gestational trophoblastic disease in 6 cases (4 cases ofHydatidiformMole, 1 case of invasive mole, 1 case of choriocarcinoma), vasa previa in one case of and chorioangioma in 2 cases.

Results

Imaging modality of the placenta Sonography remains the imaging modality of choice for evaluation of the placenta, but MRI is more benefit in advanced gestational age, obese women, and posterior placental location (1). MRI is advantageous due to the larger field of view and its multiplanar capabilities. MRI can be of added diagnostic value when further characterization is required, particularly in the setting of invasive placental processes such as placenta accreta and gestational trophoblastic disease (1, 5). Placental MRI has become an important complementary method...

Conclusion

The placenta is often overlooked in the routine evaluation of a normal gestation, receiving attention only when an abnormality is detected. Sonography remains the imaging modality of choice for evaluation of the placenta. MRI can be of added diagnostic value when further characterization is required
