CT scan is more accurate than ultrasound in detecting acute appendicitis. [15] However, ultrasound may be preferred as the first imaging test in children and pregnant women because of the risks associated with radiation exposure from CT scans. [4] Although ultrasound may aid in diagnosis, its main role is in identifying important differentials ...
Abdominal ultrasound is commonly used in the setting of abdominal pain or an acute abdomen (sudden and/or severe abdominal pain syndrome in which surgical intervention might be necessary), in which it can diagnose appendicitis or cholecystitis.

In order to diagnose Valentino's syndrome, a CT or ultrasound may be performed, which would reveal a ruptured peptic ulcer and free fluid surrounding the area of the appendix. [6] Diagnosis through laparoscopy can also be done to distinguish between acute appendicitis and Valentino's syndrome. [citation needed]
It is also a useful test to investigate acute abdominal pain (especially of the lower quadrants, whereas ultrasound is the preferred first line investigation for right upper quadrant pain). Renal stones , appendicitis , pancreatitis , diverticulitis , abdominal aortic aneurysm , and bowel obstruction are conditions that are readily diagnosed ...
An ultrasound is the preferred imaging modality in pregnant patients as CT scans expose the fetus to ionizing radiation which may lead to adverse pregnancy outcomes. [3] An abdominal x-ray may show free air in the abdominal cavity due to a perforation in the gastrointestinal tract. However, abdominal x-ray is not recommended as part of the ...
