Don't be thrown for a loop: a review of internal hernias for the abdominal imager.

Internal hernias are herniations of abdominal viscera, usually small bowel, through congenital or acquired openings of the peritoneum or mesentery. Congenital hernias may involve anatomic fossae such as the epiploic foramen as well as those related to abnormal peritoneal or mesenteric defects; these include left and right paraduodenal, transomental, transmesenteric, pericecal and broad ligament hernias. Acquired hernias are due to defects in the mesentery or peritoneum, usually resulting from prior surgeries, and include those associated with Roux-en-Y surgery as well as colorectal cancer resections. Internal hernias account for 5.8% of small obstructions. Obstructed internal hernias are considered surgical emergencies due to the high risk of bowel strangulation. This review summarizes the various types of congenital and acquired internal hernias, their relevant anatomy, embryology, associated surgical history and imaging appearance. We will also discuss a location-based approach to identifying internal hernias on CT, as well as complications and relevant signs, of which abdominal imagers should be vigilant.

Training the New Radiologists: Approaches for Education.

The field of Radiology is continually changing, requiring corresponding evolution in both medical student and resident training to adequately prepare the next generation of radiologists. With advancements in adult education theory and a deeper understanding of perception in imaging interpretation, expert educators are reshaping the training landscape by introducing innovative teaching methods to align with increased workload demands and emerging technologies. These include the use of peer and interdisciplinary teaching, gamification, case repositories, flipped-classroom models, social media, and drawing and comics. This publication aims to investigate these novel approaches and offer persuasive evidence supporting their incorporation into the updated Radiology curriculum.

Nontraumatic Vascular Emergencies of the Neck.

Nontraumatic vascular emergencies of the head and neck are uncommon, but can occur in patients with central venous catheters, head and neck infections, and in patients with head and neck cancer. Recognizing the imaging findings of vascular complications in these patient populations is critically important to ensure expeditious treatment to avoid significant morbidity and mortality.
