    Ultrasound (sonography) can help diagnose acute appendicitis, but a standard sector transducer showed lower accuracy (72%) than previous studies. Its reliability is insufficient for widespread use, though it aids in doubtful cases.

    Area of Science:

    • Medical Imaging
    • Diagnostic Ultrasound
    • Surgical Pathology

    Background:

    • Acute appendicitis diagnosis lacks a definitive radiological standard.
    • Previous studies showed high success rates (89%) for ultrasound in detecting appendicitis using specific transducers.

    Purpose of the Study:

    • To evaluate the efficacy of a standard 7.5 MHz sector transducer for diagnosing acute appendicitis.
    • To compare the diagnostic capabilities of sector transducers against linear array transducers in appendicitis detection.

    Main Methods:

    • Utilized a standard 7.5 MHz sector transducer for abdominal ultrasound examinations.
    • Assessed the ability to visualize the inflamed appendix, including retrocaecal positioning.

    Main Results:

    • Sonography correctly diagnosed acute appendicitis in 72% of cases.
    • The larger format sector transducer limited visualization of retrocaecal appendices.

    Conclusions:

    • The reliability of standard sector transducer sonography for acute appendicitis is not sufficient for large-scale application.
    • Ultrasound remains a valuable tool for diagnosing suspected acute appendicitis in ambiguous clinical scenarios.
