Ultrasound Scans

During an ultrasound, a sonographer or ultrasound technologist uses a device called a transducer or probe. You are typically asked to lie on an exam table. 

The sonographer may:

• Apply a layer of water-based gel on your skin.
• Place the transducer onto the gel at of the area or organ of interest. The gel allows the ultrasound waves to be transmitted from the transducer into your body. 
• Ask you to hold in a deep breath or change positions throughout the test to allow visualization of different structures.

Ultrasound waves bounce off organs and structures inside your body and back to the transducer. The waves are then converted by the machine into real-time images or videos, which are displayed on the computer screen. 

• Diagnosing diseases: Ultrasound can help diagnose a wide range of symptoms and conditions such as pain and swelling.
• Accessing organ function: Ultrasound images various organs/structures, including the abdominal aorta, pancreas, liver, gallbladder, kidneys, urinary bladder, spleen, thyroid, testicles, uterus and ovaries.
• Intracavity imaging: Intracavity ultrasounds are used for imaging the uterus and ovaries. Transvaginal imaging allows a more detailed image of the pelvic organs.
• Procedure planning: When abnormalities are recognized on ultrasound, physicians can plan biopsies and other treatments. Ultrasound can also be used to follow up on various conditions to see how a disease is progressing.
• Procedures: Ultrasound guidance may be used for procedures, including biopsies and fluid drainages called a paracentesis or thoracentesis.

• Non-radiation: Ultrasound does not use radiation. Research shows ultrasound to be safe with no known harmful side effects.
• Cost-Effective: In some cases, ultrasounds can be a more cost-effective test to gather information than more invasive procedures like surgery. Ultrasounds can also help avoid unnecessary procedures by providing clear and accurate diagnostic information.
• Fast results: Most ultrasound exams are completed within 30 minutes or less, with results usually within 24 hours.
• Supports treatment planning: Helps doctors make informed decisions about your care.
• Non-invasive: Most ultrasound exams, excluding procedures and intracavity exams, are non-invasive.

Discomfort or pain.

• Lying still: You will need to lie still on the scanning table, which may be uncomfortable if you have pain or a recent injury.
• Pressure: You may experience pressure during the exam due to the transducer placement required to obtain the imaging.

Interference with scan accuracy.

Certain factors can affect the clarity and accuracy of your Ultrasound scan results. Here’s what to keep in mind:

• Movement during the scan: Staying still is essential. Any movement—even small shifts—can blur the images and make it harder for doctors to interpret them. If you have a condition that makes it difficult to lie still, let your care team know so they can help.
• Recent food or drink: For scans that require fasting, eating or drinking too close to your appointment may affect image quality. Follow all prep instructions carefully.
• Medications: Some medications such as blood thinners—might need to be stopped before and after your Ultrasound-guided procedure. Your doctor will let you know what’s best for you.
• Anxiety or discomfort: Feeling anxious or uncomfortable can make it harder to stay still. If you’re concerned, talk to your provider.
