A basic pet ultrasound is a quick, focused scan your vet uses to answer one question, such as whether the bladder holds stones or the belly holds fluid, usually during the same visit as the exam. Petfolk Veterinary & Urgent Care - Ballantyne is a vet clinic on Ballantyne Commons Parkway in Charlotte, North Carolina, that offers basic ultrasound for dogs and cats alongside the exam, lab work and x-rays.
Ultrasound uses sound waves, not radiation. A probe on the skin sends out sound, and the echoes build a live picture on a screen. All Petfolk care centers offer basic ultrasound; advanced services vary by location. Call (980) 300-6982 or book online.
What is ultrasound used for most at Petfolk Ballantyne?
At Petfolk Ballantyne, 81% of ultrasounds were used to guide a needle into the bladder for a sterile urine sample, a procedure called cystocentesis, from October 2025 to September 2026. An ultrasound was part of 17% of the clinic's visits for urinary problems in that period.
Across Petfolk's Charlotte-area clinics in the same 12 months, 63% of ultrasound services guided a urine sample, and 19% were quick FAST scans, short focused looks at the belly or chest for free fluid.
What can a basic scan show?
A focused scan answers a specific question the vet has after examining your pet.
The bladder. How full it is, bladder stones or sludge, and a thickened wall that fits with inflammation. This is common in cats and dogs straining to pee.
A clean urine sample. Ultrasound guides a fine needle into the bladder through the belly wall. That sterile sample makes a urine culture (a test that grows bacteria to name them) more accurate than a sample caught from the floor.
Free fluid in the belly or chest. Fluid where it should not be has a short list of causes, and finding it narrows the next test.
Pregnancy. A scan can confirm pregnancy and show heartbeats, earlier than an x-ray.
A guided needle sample. For some lumps or fluid pockets, ultrasound helps the vet place a needle exactly.

What a basic scan does not replace
A basic scan does not replace a full abdominal ultrasound, where every organ is measured and examined in detail, or an echocardiogram (an ultrasound of the heart). Both take specialist training and equipment. If blood work or an x-ray raises a question that needs that level of detail, the Petfolk Ballantyne vet will explain the referral and send your records ahead, so your pet gets the right test the first time.
How do I get my pet ready for an ultrasound?
Preparing for a scan takes four small steps.
Ask about food. For a belly scan, the vet may ask you to hold breakfast, since a full stomach and gas blur the picture.
Ask about the last pee. If the bladder is being checked, the vet may ask you not to let your dog pee right before the visit. A full bladder is easier to see.
Expect a shaved patch. Fur traps air, which blocks sound waves. A small area of the belly is clipped, and it grows back.
Tell the team about nerves. Most pets lie on their back or side on a padded surface. Fear-free handling is standard at every Petfolk clinic, with treats and padding to keep things calm.
You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit. The vet explains what the results mean at the same visit when possible.
Where ultrasound fits with x-rays and blood work
Ultrasound rarely works alone. A pet with vomiting might have an exam, then blood work, then x-rays, and then a scan of the stomach and bladder, and each test answers a different question. If you are coming from Stallings or another town further out, bring any past test results so the vet can compare.
Signs to skip the scan and go to a 24-hour hospital
Go to a 24-hour emergency hospital now if your pet collapses, has a swollen and tight belly or pale gums, or is straining to pee with nothing coming out, especially a male cat. A blocked bladder can become life-threatening within a day. Petfolk Ballantyne does not provide overnight care.
