Ep 222 Imaging Decisions in Emergency Medicine

When to image, when to wait, and what to do when the ideal test isn’t available are often far more nuanced than they appear. In this EM Cases episode, Dr. Amit Shah joins Anton to tackle some of the toughest everyday imaging decisions: How much should cumulative radiation exposure influence our decision to order another CT? In suspected appendicitis, when is it safe to wait for ultrasound rather than obtain CT overnight? Can the emerging traumatic brain injury biomarkers GFAP and UCH-L1 help avoid CT, particularly in rural and remote settings? And in suspected cauda equina syndrome, how can PVR and CT lumbar spine be combined to risk-stratify patients when MRI isn’t immediately available—and when should a reassuring PVR or CT not reassure us?

Episode 1: Occult Fractures and Dislocations

Dr. Arun Sayal and Dr. Natalie Mamen discuss the key diagnostic considerations in commonly missed occult fractures and dislocations. They review the indications and controversies for the use of Bone Scan, CT and MRI in occult fractures and dislocations and give you some great clinical pearls to use on your next shift. Missed occult fractures and dislocations, in general, may result in significant morbidity for the patient and law suites for you. Six cases are presented in this episode, ranging from common scaphoid fractures to rarer dislocations. Dr. Sayal & Dr. Mamen answer questions such as: Which fractures can mimic ankle sprains and how do you avoid missing them? What are the most reliable signs of scaphoid fracture? In which occult orthopaedic injuries should we anticipate limb threatening ischemia? Which is better to diagnose occult fractures - MRI or CT? Which calcaneus fractures require surgery and which ones can be managed conservatively? and many more......
