2025年1月13日 · Acute appendicitis is an acute inflammation of the vermiform appendix. It is a very common condition in general radiology practice and is one of the main reasons for abdominal surgery in young patients. CT is the most sensitive modality to detect 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.

2020年7月5日 · In the diagnosis of appendicitis the most valuable lab findings are WBC (White Bloodcell Count) and CRP (C- Reactive Protein). In early acute appendicitis, the WBC rapidly increases within a few hours and often returns to normal after 12 - 24 hours.

Typically, the high frequency linear array transducer (7-12 MHz) is used to scan and evaluate the appendix. In patients with a larger body habitus the lower frequency probes (curvilinear or phased-array) allow for deeper penetration albeit sacrificing some of the image resolution.

2016年2月16日 · • 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.

2005年1月1日 · When the diagnosis of appendicitis is uncertain, computed tomography (CT) and ultrasonography may reduce the rate of perforation. The diagnostic accuracy of ultrasonography for acute appendicitis...

2024年6月14日 · Ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) have high diagnostic accuracy in the diagnosis of acute appendicitis. Nowadays imaging is part of the diagnostic algorithm of appendicitis and the advantages are demonstrated by the reduced negative appendectomies rates.

2024年2月20日 · In one meta-analysis, ultrasound has sensitivity and specificity of 69% and 81%, respectively, for the diagnosis of acute appendicitis. 1. CT is highly sensitive (94-98%) and specific (up to 97%) for the diagnosis of acute appendicitis and allows other causes of abdominal pain to be diagnosed.

2023年10月5日 · In this review of 8555 ultrasound examinations at our institution, we demonstrate gold-standard accuracy of ultrasound in the diagnosis of paediatric acute appendicitis.

Main Messages • 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.
