Unluer et al compared bedside ultrasound and radiology ultrasound to clinical course and surgical findings.  174 patients. Bedside and radiology ultrasound were found to have similar test characteristics and both exceeded plain film radiography.

Ultrasonography by emergency medicine and radiology residents for the diagnosis of small bowel obstruction. Unlüer EE, Yava?i O, Ero?lu O, Yilmaz C, Akarca FK. Eur J Emerg Med. 2010 Oct;17(5):260-4. doi: 10.1097/MEJ.0b013e328336c736. PMID: 20216422

Jang et al found that bedside ultrasound outperformed plain films using ct as gold standard in 76 patients.

Bedside ultrasonography for the detection of small bowel obstruction in the emergency department. Jang TB, Schindler D, Kaji AH. Emerg Med J. 2011 Aug;28(8):676-8. doi: 10.1136/emj.2010.095729. Epub 2010 Aug 22. PMID: 20732861



This radiology study meta-analysis of 630 ultrasound patients and 684 ct patients found US test characteristics to be non-inferior to CT.

Graded compression ultrasonography and computed tomography in acute colonic diverticulitis: meta-analysis of test accuracy. Laméris W, van Randen A, Bipat S, Bossuyt PM, Boermeester MA, Stoker J. Eur Radiol. 2008 Nov;18(11):2498-511. PMID: 18523784


Fox compared bedside ultrasound in 126 patients to either path report for those that underwent appendectomy or telephone follow up if they didn’t. They achieved excellent  specificity 90% – but mediocre sensitivity – only 65%. This is one way we use very commonly use ultrasound, though – as a rule in only modality.

Prospective evaluation of emergency physician performed bedside ultrasound to detect acute appendicitis. Fox JC, Solley M, Anderson CL, Zlidenny A, Lahham S, Maasumi K. Eur J Emerg Med. 2008 Apr;15(2):80-5. doi: 10.1097/MEJ.0b013e328270361a. PMID: 18446069

Jim Tsung’s 2014 study found 100% sensitivity with a strict technique – their protocol required the appendix to be fully visualized from tip to cecum in long view and then transversely throughout the same course. This resulted in a higher number of equivocal studies, but no false negative laparotomies.  Having no false negative laparotomies builds real trust with your pediatric surgeons.

The effect of point-of-care ultrasonography on emergency department length of stay and computed tomography utilization in children with suspected appendicitis. Elikashvili I, Tay ET, Tsung JW. Acad Emerg Med. 2014 Feb;21(2):163-70. doi: 10.1111/acem.12319. PMID: 24673672



Summers and Fox found test characteristics in BUS noninferior to RUS.

A prospective evaluation of emergency department bedside ultrasonography for the detection of acute cholecystitis. Summers SM, Scruggs W, Menchine MD, Lahham S, Anderson C, Amr O, Lotfipour S, Cusick SS, Fox JC. Ann Emerg Med. 2010 Aug;56(2):114-22. doi: 10.1016/j.annemergmed.2010.01.014. PMID: 20138397

Villar’s and Fox’s study – looked at data from a prior study comparing gallstones along vs. stones + secondary signs for the diagnosis of cholecystitis with Radiology ultrasound or pathology report as the gold standard. They found that absence of gallstones ruled out cholecystitsi with a sensitivity of 100%..

Studies like these make my life so easy.
