Zusammenfassung
Ultraschall ist immer noch die Standardmethode der Plazentauntersuchung, aber die Magnetresonanztomographie bietet Vorteile. Bei fortgeschrittenem Gestationsalter, adipösen Patientinnen und bei einer Hinterwandplazenta sind diese das größere Blickfenster und die multiplanaren Darstellungsmöglichkeiten des MRI. Auch sind einige Pathologien, wie Plazentainfarkte und Plazentainvasionsstörungen besser im MRI darstellbar. Die weitere Entwicklung geht hin zur funktionellen Bildgebung. Das Plazenta-MRI hat sich zu einer wichtigen komplementären Untersuchungsmethode entwickelt, die zur Evaluation der Plazentaanatomie und plazentaren Pathologien als Ursache für fetale Probleme wie z. B. der intrauterinen Wachstumsretardierung beitragen kann.
Summary
While ultrasound is still the gold standard method of placental investigation, magnetic resonance imaging (MRI) has certain benefits. In advanced gestational age, obese women, and posterior placental location, MRI is advantageous due to the larger field of view and its multiplanar capabilities. Some pathologies are seen more clearly in MRI, such as infarctions and placental invasive disorders. The future development is towards functional placental MRI. Placental MRI has become an important complementary method for evaluation of placental anatomy and pathologies contributing to fetal problems such as intrauterine growth restriction.
