Study: Emergency patients get duplicate x-ray, CT exams

By Brian Casey

If Domino's can track pizzas from order through delivery, why can't we keep better track of patients?

Decision model cuts unnecessary wrist x-rays by 22%

By Kate Madden Yee

Using a clinical decision model developed by Dutch researchers for pediatric wrist trauma could cut unnecessary emergency x-ray imaging for the condition by 22% -- thereby reducing children's radiation exposure and healthcare costs, according to a study published online in Pediatric Radiology.

From coins to knives: Foreign bodies run the gamut

By Kate Madden Yee

A patient presenting with a foreign body -- an object that has been swallowed, breathed in, or inserted -- is a common scene in the emergency room (ER).

Patients with CIN after CT show poor 1-year outcomes

By Eric Barnes

Patients who develop contrast-induced nephropathy (CIN) are at high risk of major adverse events one year after imaging with contrast-enhanced CT, according to a new study in the September Annals of Emergency Medicine. The experience in more than 600 patients who underwent contrast CT suggests the problem is both serious and underrecognized.

Cardiovascular emergencies such as acute aortic syndromes need to be diagnosed quickly. Fortunately, mobile devices such as the iPhone can be used for on-the-go diagnosis and triage of patients with these life-threatening conditions, according to an article published online August 3 in the Journal of Cardiovascular Computed Tomography.

ACR 2015: Bedside US may not capture whole picture in ER

By Erik L. Ridley

Emergency room (ER) physicians often perform bedside obstetric ultrasound studies on first-trimester patients in the ER, but these patients should also receive radiology ultrasound scans to avoid potentially dangerous missed diagnoses, according to research from Santa Barbara Cottage Hospital in California.

Point-of-care ultrasound can assess soft-tissue neck masses

By Erik L. Ridley

Point-of-care ultrasound is a valuable tool for pediatric emergency medicine physicians evaluating soft-tissue masses in the neck, outperforming clinical assessment, according to a pilot study from Maimonides Medical Center in New York City.

Bedside ultrasound can diagnose acute shoulder dislocation

By Erik L. Ridley

Patients presenting to the emergency department with acute shoulder pain typically receive an x-ray exam. However, ultrasound can provide equivalent performance -- often in less time and without the ionizing radiation -- for diagnosing shoulder dislocation, according to researchers from the University of California, Irvine.

Teleradiology prompts shift in use of after-hours ultrasound

By Brian Casey

Researchers in France found that concerns over who would perform after-hours emergency ultrasound scans shouldn't be a roadblock for hospitals that want to implement an overnight teleradiology service. They found that all but 14% of scans could either be replaced or postponed.
