Purpose: To directly compare of diagnostic accuracy and confidence of ultrasonography with MDCT for acute appendicitis with/without complication in same patients and to analyze affecting factors to diagnostic performance.
Learning Objects: To understand different characteristics between ultrasonography and MDCT for evaluation of appendiceal abnormalities. To analyze the false negative results of MDCT in acute appendicitis despite correct ultrasonographic diagnoses. To evaluate added values of color Doppler exams for diagnosis of acute appendicitis and complication. To help with choosing the first diagnostic modality between ultrasonography and MDCT. To consider surgeons’ views of diagnostic modalities.
Conclusion: Though MDCT is accurate and surgeons’ preference, ultrasonographic exam must be considered the first diagnostic modality in patients with acute appendicitis.
