Magnetic resonance (MR) imaging demonstrates superior accuracy compared to sonography for diagnosing acute appendicitis. MR imaging can serve as a valuable tool when sonography results are inconclusive for suspected appendicitis.

Area of Science:

  • Radiology
  • Medical Imaging
  • Gastrointestinal Imaging

Background:

  • Acute appendicitis is a frequent cause of emergency abdominal surgery.
  • Diagnostic imaging plays a crucial role in identifying appendicitis, with sonography being a common modality.
  • Comparative studies on the diagnostic performance of MR imaging versus sonography for appendicitis are limited.

Purpose of the Study:

  • To compare the diagnostic accuracy of MR imaging and sonography in detecting acute appendicitis.
  • To evaluate the advantages and limitations of both imaging modalities in the context of suspected appendicitis.

Main Methods:

  • A prospective study involving 60 patients with suspected appendicitis.
  • All patients underwent both abdominal sonography and MR imaging.

  • Imaging findings were correlated with surgical, histopathologic, and clinical outcomes.

    • Main Results:

    • MR imaging showed statistically significant higher sensitivity, accuracy, and negative predictive values compared to sonography (p < .05).
    • No significant difference was observed between MR imaging and sonography in terms of specificity and positive predictive value.
    • Appendicitis was confirmed in 34 patients, while 26 did not have the condition.

    Conclusions:

    • MR imaging is more accurate than sonography for diagnosing suspected acute appendicitis.
    • MR imaging can be a useful alternative or complementary tool following non-diagnostic or suboptimal sonography.
    • Despite some limitations, MR imaging offers superior diagnostic performance for acute appendicitis.
