Although ultrasound remains the primary imaging modality used in prenatal imaging, fetal magnetic resonance imaging (MRI) is playing an increasing role in further evaluation of fetuses suspected of congenital anomalies. As 3-T MRI scanners become more common due to their improved image signal-to-noise ratio and anatomical detail, the benefits of 3-T MRI must be weighed against potential risks to the fetus that may result from the higher field strength.

A study published in JACC: Cardiovascular Interventions showed that in-hospital and 30-day stroke or death rates were equally low with either a distal filter embolic protection device (F-EPD) or a proximal EPD (P-EPD) to protect patients from blood clots during carotid artery stenting. A small sample size for one device, however, raises questions on the study’s ability to detect potentially meaningful differences in outcomes.

The American Society of Radiologic Technologists (ASRT) has launched new online products to help members improve safety practice and dose reduction techniques for computed tomography (CT) and magnetic resonance imaging (MRI), in line with revised requirements from The Joint Commission.
