Summary
Magnetic resonance imaging (MRI) aids in diagnosing unexplained third-trimester bleeding when ultrasound is inconclusive. MRI identified placenta previa and intrauterine hematomas, offering valuable insights for patient management.
Area of Science:
- Obstetrics and Gynecology
- Radiology
- Maternal-Fetal Medicine
Background:
- Third-trimester bleeding presents diagnostic challenges.
- Transabdominal ultrasound may fail to identify the source of bleeding.
- Accurate diagnosis is crucial for maternal and fetal well-being.
Purpose of the Study:
- To evaluate the utility of magnetic resonance imaging (MRI) in diagnosing unexplained third-trimester bleeding.
- To compare MRI findings with delivery outcomes.
Main Methods:
- Fifteen patients with third-trimester bleeding and inconclusive ultrasound underwent MRI.
- MRI findings were correlated with placental location, hematomas, and cervical blood.
Main Results:
- MRI correctly identified placenta previa in three patients.
- Intrauterine hematomas were detected in four patients, with associations to previa, abruptions, or cord insertion issues.
- MRI revealed cervical blood in two patients with previa.
Conclusions:
- Magnetic resonance imaging is a valuable tool for evaluating unexplained third-trimester bleeding.
- MRI can identify placenta previa, intrauterine hematomas, and cervical blood, improving diagnostic accuracy.
