While the scan is excellent for detecting inguinal and femoral hernias, some hernias, like hiatal hernias (occurring in the upper abdomen), may not be visible on this scan and require different diagnostic methods, such as a barium swallow test or endoscopy.

Fasting is usually recommended for the abdominal portion of the scan to improve image clarity. However, no fasting is required for the inguinal region scan alone. Your healthcare provider will give specific instructions based on your case.

No, the scan is non-invasive and painless. You may feel slight pressure when the sonographer moves the probe over the abdomen or inguinal region, but it should not cause discomfort.

If a hernia is detected, your healthcare provider may recommend further evaluation or surgical consultation, depending on the size and severity of the hernia and the symptoms you are experiencing.
