In addition, the appendix cannot always be displayed successfully with ultrasonography (US). In this study, we aimed to investigate the effects of age, sex, and body mass index (BMI) on the detection of a normally vermiform appendix by US. The study included 173 patients who applied for routine US examinations with no clinical findings of appendicitis. Age, BMI (only in adult patients), and gender were recorded. We searched for the appendix in each patientusing both tissue harmonic imaging (THI) and conventional US after the routine US examinations. When the appendix was found, localisation and diameter were recorded. The two methods were compared in all patients, and the relation between the rate of visualisation and BMI was determined. The appendix was found in 59% of the patients: 50% of women, 41% of men, and 93% of children. Statistically, the detection rate was significantly higher in children. The ratios of visualisation in patients with BMIs <25 were 55% in females and 56% in males. In patients with higher BMIs, the ratios were 46% and 29%, respectively. Considering male and female patients together, the ratios were 55% in patients with BMIs <25 and 40% in patients with higher BMIs. There was a significant difference in the appendix detection rate between observers using the two imaging techniques. There are differences between observers when detecting the appendix, and there is a significant correlation between appendix visualisation and BMI. THI visualises the appendix better than conventional US does. THI and conventional US are more successful in children than in adults, and in detecting pathological appendices than normal appendices in all groups.}, number={1}, publisher={Osman Nuri DİLEK}
