Further assessment with CT or MR is indicated if the tip is not seen on US

This article reviews various CT protocols for appendicitis, identifies key CT findings for diagnosing appendicitis, discusses unusual manifestations such as chronic and recurrent appendicitis, and profiles imaging features that differentiate appendicitis from other inflammatory and neoplastic ileocecal conditions.

2024年6月2日 · Acute appendicitis is a common indication for abdominal computed tomography (CT) in younger patients presenting with fever, right lower quadrant pain and elevated white blood cell count. Acute appendicitis is also an important diagnosis to consider in older patients, although it is less common in this group.

2020年10月1日 · This analysis demonstrates that CT is a good screening test (sensitivity = 95%; 95% CI, 72% to 100%) and a good confirmatory test (specificity = 94%; 95% CI, 50% to 100%).

2024年2月20日 · 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. Usually performed with IV contrast (no oral contrast required). In one study, the sensitivity and specificity of MRI for the diagnosis of acute appendicitis are 96% and 96%, respectively.

When using CT to diagnose appendicitis, there are 2 main options: the standard abdominal and pelvic scan and the appendiceal scan with rectal contrast. The former displays classic patterns such as concentric, thickened appendiceal walls; an appendicolith, fat …

A CT scan for appendicitis is a valuable tool for diagnosing this potentially life-threatening condition. Its high accuracy, speed, and detailed imaging capabilities can significantly aid doctors in making prompt treatment decisions.

Classically, the diagnosis of appendicitis is made using the appendicular outer-to-outer wall diameter. In this study, we examined the sensitivity and specificity of computed tomography (CT) scans for diagnosing acute appendicitis using wall thickness and …

This article reviews various CT protocols for appendicitis, identifies key CT findings for diagnosing appendicitis, discusses unusual manifestations such as chronic and re-current appendicitis, and profiles imaging features that differentiate appendicitis from other in-flammatory and neoplastic ileocecal conditions.

2005年1月1日 · An inflamed appendix revealed on a CT scan is larger than 6 mm in diameter, and has appendiceal wall thickening and wall enhancement after contrast media infusion. 32, 33 CT scans also can reveal...
