This must be balanced against the negative appendicectomy rate, which is higher in pre-menopausal females compared to males due to acute gynaecological conditions, Evidence suggests that preoperative imaging of suspected appendicitis is associated with a significantly lower rate of negative appendicectomies, without delaying the time-to-surgery, or the perioperative complication rate. In surgery performed for suspected appendicitis, the pre-operative diagnosis is correct in only about 50% of cases[1].

In suspected acute appendicitis, imaging can significantly reduce the negative appendicectomy rate but must not delay treatment, Both ultrasound and CT are accurate for the diagnosis of appendicitis, Ultrasound is generally preferable as the first investigation in young patients because, It can detect gynaecological causes of acute pain in young female patients, Has a sensitivity and specificity of approximately 75-90% and 78-100% respectively for the diagnosis of acute appendicitis, Performed using the graded compression technique, which involves applying anterior compression to reduce the depth of the abdominal cavity between the appendix and the transducer, Features of appendicitis on ultrasound include, An outer appendix diameter of 6mm or larger, Echogenic periappendiceal inflammatory fat change, Non-invasive and involves no exposure to ionizing radiation, Can diagnosis an alternate cause for abdominal pain, If necessary can be used with transvaginal ultrasound to provide information regarding the uterus, adnexa and ovaries in young women with right lower quadrant / pelvic pain, Lower sensitivity and specificity for perforated appendicitis, Less accurate with obese patients and those with a retrocaecal appendix, Tubo-ovarian pathology and ectopic pregnancy in females, Pelvic inflammatory disease (salpingitis, tubo-ovarian abscess), Ovarian cyst accident (ruptured ovarian cyst, haemorrhage, ovarian or fallopian tube torsion), Has a sensitivity and specificity of approximately 76-100% and 83-97% respectively for the diagnosis of acute appendicitis, The scanning technique has varied between studies with some using no contrast agents and others using one or more of oral, intravenous and rectal contrast.
