Introduction

An abdominal ultrasound scan is a safe imaging test. It uses sound waves to create pictures of organs inside your belly. Doctors often use this test to check for problems in the liver, kidneys, gallbladder, and other organs. Because it is painless and does not use radiation, many people prefer it. In this blog, you will learn about the abdominal ultrasound procedure, why it is done, how to prepare, and what the results mean.

What is an Abdominal Ultrasound Scan?

An abdominal ultrasound scan is a type of medical imaging. It helps doctors see inside your abdomen, which is the area between your chest and hips. The scan uses high-frequency sound waves. These waves bounce off your organs and create images on a screen. Since it does not use X-rays, it is very safe. Doctors use this test to look at organs like the liver, pancreas, spleen, kidneys, and bladder.

Why is it Done?

Doctors order an abdominal ultrasound for many reasons. Sometimes, you may have symptoms that need checking. For example, you might have:

  • Stomach pain or swelling
  • Unexplained weight loss
  • Yellowing of the skin (jaundice)
  • Blood in your urine
  • Kidney stones or gallstones
  • In addition, doctors use this scan to check for:

  • Liver disease
  • Kidney problems
  • Gallbladder issues
  • Abnormal growths or tumors
  • Fluid in the abdomen
  • Because it is quick and safe, doctors often choose this test first when you have belly symptoms.

    How is the Procedure Performed?

    During the abdominal ultrasound procedure, you will lie on your back on a table. A technician, called a sonographer, will help you get comfortable. Next, they will put a warm gel on your skin. This gel helps the sound waves travel better. Then, the sonographer moves a small device, called a transducer, over your belly. The device sends sound waves into your body. These waves bounce back and form images on a screen.

    The scan usually takes 20 to 30 minutes. You may be asked to hold your breath for a few seconds. This helps get clearer pictures. After the scan, the gel is wiped off. You can go home right away. Most people feel no pain during the test.

    Preparation Tips for Patients

    Proper ultrasound scan preparation helps get the best results. Your doctor will give you instructions. However, common tips include:

  • Do not eat or drink for 8 hours before the test, unless told otherwise.
  • Wear loose, comfortable clothing.
  • Arrive on time for your appointment.
  • Bring a list of your medicines.
  • Tell your doctor if you are pregnant.
  • Sometimes, you may need to drink water and hold your urine. This helps see the bladder better. Always follow your doctor’s advice for the best results.

    What Do the Results Mean?

    After the abdominal imaging test, a doctor will review your images. They look for signs of disease or injury. For example, they may check for:

  • Swelling or changes in organ size
  • Stones in the kidney or gallbladder
  • Fluid buildup
  • Unusual growths or tumors
  • Sometimes, the scan shows normal results. Other times, it may find a problem that needs more tests. Your doctor will explain what the results mean for you. If needed, they may suggest more tests or treatment.
