Invasive placental disorders: a prospective US and MRI comparative analysis

Area of Science:

• Obstetrics and Gynecology
• Diagnostic Imaging
• Radiology

Background:

• Invasive placental disorders pose significant life-threatening risks.
• Accurate diagnosis and assessment of invasiveness are critical for surgical and treatment planning.

Purpose of the Study:

• To compare imaging modalities for evaluating invasive placental disorders.
• To assess the validity of specific imaging signs in predicting placental invasiveness.

Main Methods:

• Twenty-two high-risk patients underwent Doppler sonography and MRI.
• Evaluation of placental invasiveness using established Doppler sonography and MRI signs.
• Correlation of imaging findings with surgical and pathological outcomes.

Main Results:

• MRI correctly identified 8 out of 9 invasive placental cases (89% sensitivity).
• Doppler sonography correctly identified all 9 invasive placental cases (100% sensitivity).
• MRI demonstrated higher accuracy in predicting bladder invasion (5/6 cases).

Conclusions:

• Both MRI and Doppler sonography are valuable tools for detecting invasive placental disorders.
• MRI offers superior performance in predicting bladder invasion associated with these disorders.
