Diagnosing appendicitis is challenging. High-resolution ultrasonography (US) demonstrated high accuracy (0.92) in detecting appendicitis in patients with suspected cases, aiding clinical decisions.

Area of Science:

  • Medical Imaging
  • Gastroenterology
  • Surgical Diagnostics

Background:

  • Appendicitis diagnosis is often difficult, leading to imprecise surgical indications.
  • Improved diagnostic methods are needed to detect inflammatory changes in the appendix accurately.

Purpose of the Study:

  • To evaluate the diagnostic performance of high-resolution ultrasonography (US) in patients with clinically suspected appendicitis.

Main Methods:

  • High-resolution ultrasonography (US) was performed on 37 patients over eight months.
  • US findings were validated through surgical confirmation, pathology, and clinical follow-up.

Main Results:

  • High-resolution US achieved a sensitivity of 0.87.
  • The modality showed a specificity of 0.95 and an overall accuracy of 0.92.

Conclusions:

  • High-resolution ultrasonography (US) is a valuable tool for evaluating suspected appendicitis.
  • US improves diagnostic accuracy, supporting clinical decision-making in appendicitis cases.
