Stomach pain in children is common, but it can be challenging to determine the cause without proper diagnostic tools. An Abdomen and pelvis scan is a non-invasive and effective way to evaluate the underlying reasons for abdominal discomfort.
It uses sound waves to create detailed images of the internal organs, helping doctors identify conditions like appendicitis, gastrointestinal issues, urinary problems, and more.
Common Causes of Abdominal Pain in Children

It’s important to be aware that abdominal pain in children can sometimes be related to conditions that require ultrasound imaging. Common causes include:
- Appendicitis: Inflammation of the appendix, causing severe pain, nausea, and vomiting.
- Gastrointestinal Issues: Constipation, gas, indigestion, or infections leading to stomach pain.
- Urinary Tract Infections (UTIs): Causing discomfort or pain in the lower abdomen.
- Intestinal Obstruction: Blockage in the intestines leading to cramps, vomiting, and bloating.
- Hernias: Causing localized pain and swelling.
In some cases, a pediatric abdomen ultrasound is recommended to diagnose these conditions accurately.

How Ultrasound Identifies Appendicitis in Real-Time
Ultrasound is an effective tool for diagnosing appendicitis in children because it provides real-time imaging of the abdomen. It helps in:
- Visualizing the Appendix: An enlarged, swollen, or inflamed appendix is clearly visible on the scan.
- Detecting Fluid Accumulation: Fluid or abscess around the appendix can indicate infection.
- Assessing Blood Flow: Doppler ultrasound assesses blood flow to the appendix, helping to identify inflammation or reduced blood supply.
This non-invasive method is safe for children and provides quick, accurate diagnosis without radiation exposure.
Detecting Gastrointestinal Issues with Ultrasound
Ultrasound is also used to identify various gastrointestinal issues in children, including:
- Intussusception: A condition where a portion of the intestine folds into another section, causing blockage.
- Pyloric Stenosis: Thickening of the pyloric muscle, leading to vomiting and feeding difficulties in infants.
- Gallstones or Kidney Stones: Causing abdominal or flank pain.
- Bowel Obstructions: Identifying areas of blockage or inflammation.
Ultrasound is particularly useful for pediatric patients as it is non-invasive, quick, and painless.

When to Take Your Child for an Abdomen Ultrasound

Consider an abdomen ultrasound for your child if they experience:
- Persistent or severe abdominal pain.
- Vomiting, diarrhea, or constipation lasting more than a few days.
- Unexplained swelling or bloating.
- Blood in stool or urine.
- Pain during urination or signs of a urinary tract infection.
A pediatrician will recommend an ultrasound if needed to ensure accurate diagnosis and appropriate treatment.
Understanding the Results of Your Child’s Ultrasound Scan
After the ultrasound, a radiologist analyzes the images and prepares a report. The results can help:
- Confirm or rule out conditions like appendicitis, intussusception, or bowel obstructions.
- Detect abnormalities such as cysts, tumors, or fluid accumulation.
- Guide further testing or treatment, if necessary.
Your doctor will discuss the findings with you and provide the next steps based on the results.
