Ultrasonography for acute appendicitis - the way it looks today
Diagnosing acute appendicitis remains challenging. Ultrasonography (US) is a reliable method, especially for complex cases, while computed tomography (CT) reduces false negatives but involves radiation exposure.
Area of Science:
- Medical Imaging
- Diagnostic Radiology
Background:
- Acute appendicitis diagnosis is challenging, with negative appendectomy rates of 15-30%.
- Ultrasonography (US) has been a reliable diagnostic tool since 1986, aiding in difficult and atypical cases.
- Multidetector computed tomography (CT) reduces false negatives but raises concerns about radiation exposure, particularly in children.
Purpose of the Study:
- To re-evaluate the role of ultrasonography (US) and computed tomography (CT) in diagnosing acute appendicitis.
- To emphasize the importance of proper US technique and judicious CT use.
Main Methods:
- Review of recent publications on imaging modalities for acute appendicitis.
- Comparison of ultrasonography (US) and multidetector computed tomography (CT) efficacy and risks.
Main Results:
- Ultrasonography (US) remains a valuable tool, especially for atypical presentations.
- Computed tomography (CT) offers high sensitivity but carries risks of radiation exposure.
- Inadequate US performance can lead to unnecessary CT scans.
Conclusions:
- A renewed focus on the performance and role of ultrasonography (US) in acute appendicitis diagnosis is warranted.
- Judicious application of imaging, prioritizing US, is crucial to balance diagnostic accuracy and patient safety.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
