Nevertheless, ultrasound has limitations.
Gas within the intestines, the patient’s anatomy, and the location of an abnormality can affect what is visible.
An inconclusive ultrasound does not necessarily mean that nothing is wrong.
Computed tomography, commonly called a CT scan, creates detailed cross-sectional images of the body.
CT imaging can help identify certain masses, obstructions, inflammatory processes, and other abnormalities.
However, it exposes patients to ionizing radiation, so doctors carefully consider its benefits and risks, especially for children and adolescents.
Magnetic resonance imaging, or MRI, may provide an alternative for some conditions without using ionizing radiation.
The National Institute of Diabetes and Digestive and Kidney Diseases describes ultrasound, CT, and MRI as tools clinicians may use when evaluating abdominal conditions such as appendicitis, with the choice influenced by patient characteristics and clinical needs.

The central lesson is that imaging should answer a specific medical question.
An investigation is most useful when doctors understand what they are looking for and how the result will affect treatment.
