Reference Methods Results Notes Costantino et al. 2005 [ 9 ] Accuracy comparison of emergency physician (EP)- performed US vs. CT, MRI, or operative findings. EP-performed US had a sensitivity of 94% and a specificity of 100%. Regression of EP-performed US AAA diameter was strongly correlated ( r 2 ¼ 0.92). More evidence supporting the accuracy of US performed by emergency physicians. Salen et al. 2003 [ 10 ] Prospective observational study of test characteristics of EP-performed bedside US in diagnosis of AAA. If AAA found by EP, radiology US was performed. 125 suspected AAA cases. PPV 75% compared to radiology US, MRI, or laparotomy (6 true positives, 2 false positives by EPs). Gold standard only applied to patients who screened positive for AAA by emergency physicians. 130 Diagnostic ultrasound Abdominal aorta ultrasound

6 Renal and bladder ultrasound Introduction The kidney and bladder are two of the most sonographically accessible organs. The evidence for using ultrasound to make lifesaving diagnoses in this application is not as apparent as it is for cardiac or aortic ultra- sound (except, of course, if flank pain and hydronephrosis are the result of a rapidly expanding AAA – see Chapter 5 ). Indeed, it is accurate to say

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
