2020年2月14日 · This Five Minute Sono video is a detailed guide on using ultrasound to diagnose appendicitis, covering probe selection, patient positioning, and specific techniques for locating the appendix and identifying appendicitis.

• Ultrasound (US) should be the first imaging modality for diagnosing acute appendicitis (AA). • Primary US for AA diagnosis will decrease ionizing radiation and cost. • Sensitivity of US to diagnose AA is lower than of CT/MRI. • Non-visualization of the …

2021年11月22日 · Appendicitis is difficult to diagnose due to the early nonspecific generalized symptoms (anorexia, generalized pain, nausea, diarrhea or constipation). We can use point of care ultrasound (POCUS) to help evaluate your differential diagnosis.
