Evaluation of Diagnostic Accuracy of Ultrasonography and Low Dose Computed Tomography in Acute Appendicitis
Keywords:USG, Computed tomography, acute appendicitis, LDCT.
In acute appendicitis, abdominal Ultrasonography (USG) to reach a stable diagnosis and use of Low Dose
Computed Tomography (LDCT) in the diagnosis of acute appendicitis is crucial. This study aimed at
assessing of the accuracy of imaging modalities (USG and LDCT) in the diagnosis of children and adults
with acute appendicitis to minimize the rate of negative appendectomyA total of 42 patients, children and
adults were examined, were included in this research (16 females and 26 males) ages was ranged from 5 to
45 years. All patients were examined byUSG and LDCT to diagnosis acute appendicitis . The sensitivity
of low dose a LDCT scan was used to diagnose acute appendicitis (96.0%) that means LDCT was able to
diagnosed (96.0%) Correctly diagnose acute appendicitis patients. The specificity of LDCT in the diagnosis
of acute appendicitis was (50.0%) that mean LDCT was able to diagnosed half of those with diagnosis other
than acute appendicitis correctly, But the sensitivity of USG in diagnosis of acute appendicitis was (54.1%)
that mean ultrasound was able to diagnosed (54.1%) of patients diagnosed by CT scan as acute appendicitis
correctly.The use of low-dose computerized tomography (LDCT) provides significantly higher diagnostic
accuracy compared to ultrasound for the detection of acute appendicitis.
