Objective To explore the value of prenatal color Doppler ultrasound and magnetic resonance imaging (MRI) in the diagnosis of invasive placenta previa. Methods Eighty patients with invasive placenta previa who were admitted to our hospital between January 2024 and January 2025 were selected and divided into two groups based on different diagnostic methods. The control group was diagnosed with prenatal ultrasound, while the observation group was diagnosed with MRI. The diagnostic efficacy of the two groups was compared. Results There was no significant difference in sensitivity, specificity, missed diagnosis rate, misdiagnosis rate, and diagnostic accuracy between the two groups (P>0.05). Conclusion In the prenatal diagnosis of dangerous placenta previa, both color ultrasound and MRI have shown significant diagnostic efficacy. They are not only economical, safe and reliable, but also have many advantages such as non invasiveness, easy operation, and repeatable examination. For patients who require further clarification of their placental implantation status, they may be arranged to undergo in-depth MRI examination at their discretion.
