Fetal MRI is less dependent on variables like amniotic fluid volume and fetus position compared to sonography, making it a more reliable method for detecting cleft lip and palate. Soft palate defects can also be visualized on fetal MRI, which is essential for predicting potential complications after birth.

A new CT-based classification system has been proposed to improve surgical planning and outcomes for patients with acetabular fractures. The system can clearly define the type of fracture, location, and position of principal fragments, enabling preoperative surgical planning that leads to shorter operating times and recovery periods.
A new study found that D-dimer tests can eliminate the need for CT angiograms of the lungs in 60% of cases, where the result is negative. The test measures the amount of D-dimer in blood, a breakdown product of fibrin, which forms blood clots.
A study of 273 family physicians and obstetricians found that many doctors overestimated the risk of major fetal malformations from X-rays and CT scans. Most diagnostic imaging exams result in less than 50 mGy of radiation exposure to the fetus, dispelling a misconception that can lead to unnecessary anxiety and terminations.
