When a pet is experiencing vomiting, abdominal pain, weight loss, appetite changes, abnormal bloodwork, or another unexplained illness, an abdominal ultrasound can provide important information about what is happening inside the body.

Desert Forest Animal Hospital offers abdominal ultrasound for dogs and cats in Cave Creek. We can often arrange same-day ultrasound appointments, depending on availability and your pet’s medical needs.

Ultrasound allows our veterinary team to evaluate the size, shape, structure, and movement of abdominal organs in real time. It can help identify inflammation, fluid, organ enlargement, intestinal abnormalities, gallbladder disease, urinary problems, and masses that may not be detected through a physical examination alone.

Call (480) 488-2010 to ask about same-day abdominal ultrasound availability.

What Is a Veterinary Abdominal Ultrasound?

Abdominal ultrasound is a noninvasive diagnostic imaging procedure that uses high-frequency sound waves to create images of your pet’s internal organs.

Unlike an X-ray, ultrasound does not use ionizing radiation. It provides real-time images of soft tissues and allows the veterinarian to examine internal organ structure, movement, blood vessels, and fluid within the abdomen.

An abdominal ultrasound may evaluate the:

• Liver

• Gallbladder and bile ducts

• Spleen

• Stomach

• Small and large intestines

• Pancreas

• Kidneys

• Adrenal glands

• Urinary bladder

• Abdominal lymph nodes

• Reproductive organs

• Prostate gland

• Abdominal blood vessels

• Abdominal cavity for abnormal fluid

Ultrasound and X-rays provide different types of information. In many cases, the two tests are used together to give the veterinarian a more complete understanding of your pet’s condition.

Same-Day Abdominal Ultrasound in Cave Creek

When a pet is ill, waiting several days for diagnostic imaging can be stressful. Desert Forest Animal Hospital can often provide or coordinate a same-day abdominal ultrasound during regular business hours.

Same-day availability depends on:

• The urgency of your pet’s condition

• The ultrasound schedule

• Whether fasting or stabilization is needed

• Whether additional bloodwork or X-rays are recommended

• Whether your pet requires sedation

• Whether specialist interpretation or additional procedures are necessary

Please call before arriving. Our team can review your pet’s symptoms and determine the safest and most appropriate next step.

For rapidly worsening illness, collapse, pale gums, severe pain, repeated vomiting, difficulty breathing, or a swollen abdomen, contact us about urgent veterinary care during business hours.

When Might a Pet Need an Abdominal Ultrasound?

Your veterinarian may recommend an abdominal ultrasound when a pet has symptoms or test results suggesting a problem involving an internal organ.

Common reasons include:

• Persistent or repeated vomiting

• Diarrhea

• Loss of appetite

• Unexplained weight loss

• Abdominal pain

• Abdominal swelling

• Increased thirst or urination

• Difficulty urinating

• Blood in the urine

• Jaundice

• Fever

• Weakness or collapse

• Pale gums

• Abnormal liver or kidney values

• Anemia

• A suspected abdominal mass

• An enlarged organ

• Changes found on an X-ray

• Monitoring a previously diagnosed condition

• Cancer staging

• An abnormal finding during a wellness examination

Ultrasound may also be recommended when bloodwork is abnormal even though a pet is not yet showing obvious symptoms.

Conditions an Abdominal Ultrasound May Help Identify

Abdominal ultrasound can help detect or further evaluate a wide range of conditions in dogs and cats.

Pancreatitis

Pancreatitis is inflammation of the pancreas. Dogs may develop vomiting, abdominal pain, loss of appetite, weakness, diarrhea, or fever. Cats often have less specific signs such as reduced appetite, weight loss, lethargy, dehydration, or occasional vomiting.

Ultrasound may reveal:

• Enlargement or changes in the pancreas

• Inflammation of tissues surrounding the pancreas

• Fluid near the pancreas

• Reduced intestinal movement

• Changes involving the nearby stomach or intestine

Ultrasound findings must be considered together with symptoms, physical examination, bloodwork, and pancreatic laboratory testing. A normal ultrasound does not completely rule out pancreatitis, particularly in cats.

Intestinal Disease

Ultrasound allows the veterinarian to evaluate the thickness and layering of the stomach and intestinal walls.

It may help identify changes associated with:

• Inflammatory bowel disease

• Chronic enteropathy

• Severe gastroenteritis

• Intestinal obstruction

• Foreign material

• Intestinal masses

• Abnormal intestinal movement

• Intestinal perforation

• Intussusception

• Enlarged abdominal lymph nodes

Some inflammatory and cancerous intestinal diseases can look similar on ultrasound. Additional testing, such as needle sampling, endoscopy, or surgical biopsy, may be necessary to determine the exact cause.

Lymphoma

Lymphoma is a cancer of lymphocytes, a type of white blood cell. It can affect the intestinal tract, liver, spleen, kidneys, or abdominal lymph nodes.

Ultrasound may detect:

• Thickening or loss of normal intestinal wall layers

• Enlarged abdominal lymph nodes

• Changes in the liver or spleen

• Kidney enlargement or abnormal kidney structure

• Abdominal masses

• Abnormal fluid

Ultrasound can raise concern for lymphoma and help identify an appropriate area for sampling, but imaging alone generally cannot confirm the diagnosis. Cytology, biopsy, or other laboratory testing is often needed.

Splenic Masses and Tumors

The spleen is a common site of masses in older dogs. Some splenic masses are benign, while others are malignant tumors such as hemangiosarcoma.

Ultrasound can help evaluate:

• The size and structure of the spleen

• One or more splenic masses

• Nodules within the spleen

• Evidence of abdominal bleeding

• Changes in the liver or other organs

• Enlarged lymph nodes

• Findings that may affect surgical planning

Ultrasound cannot reliably determine whether every splenic mass is benign or malignant. Surgical removal and microscopic examination may be needed for a definitive diagnosis.

A ruptured splenic mass can cause internal bleeding. Collapse, weakness, pale gums, rapid breathing, or a suddenly enlarged abdomen requires immediate veterinary attention.

Gallbladder Mucocele

A gallbladder mucocele occurs when thickened mucus and bile accumulate inside the gallbladder. As the condition progresses, it can obstruct bile flow, damage the gallbladder wall, or lead to rupture and life-threatening bile leakage into the abdomen.

An ultrasound may reveal the characteristic organized material within the gallbladder and can assess:

• Gallbladder contents

• Gallbladder-wall integrity

• Bile-duct dilation

• Surrounding inflammation

• Evidence of leakage or rupture

• Changes in the liver

Possible symptoms include vomiting, reduced appetite, abdominal pain, lethargy, jaundice, fever, diarrhea, or abdominal swelling. Some gallbladder mucoceles are discovered before severe symptoms develop.

Prompt diagnosis is important because some dogs require surgery to remove the gallbladder.

Liver Disease and Liver Masses

An abdominal ultrasound can evaluate the liver’s size, texture, edges, blood vessels, and internal structure.

It may help identify:

• Liver enlargement

• Liver nodules or masses

• Cysts

• Changes associated with inflammation

• Bile-duct obstruction

• Gallbladder disease

• Abnormal blood vessels

• Evidence of cancer

• Changes associated with chronic liver disease

Ultrasound abnormalities do not always reveal the exact cause of liver disease. Blood testing and tissue sampling may be recommended.

Kidney and Urinary Tract Disease

Ultrasound provides detailed images of the kidneys and urinary bladder.

It may help evaluate:

• Kidney stones

• Bladder stones

• Kidney or bladder masses

• Urinary obstruction

• Kidney infection

• Structural kidney changes

• Cysts

• Congenital abnormalities

• Bladder-wall thickening

• Blood clots

• Sediment within the bladder

• Changes associated with chronic kidney disease

An ultrasound is often combined with bloodwork and urinalysis to evaluate urinary and kidney concerns.

Adrenal Gland Disease

The adrenal glands are small organs located near the kidneys. They produce hormones that influence metabolism, blood pressure, stress responses, and electrolyte balance.

Ultrasound may reveal:

• Adrenal enlargement

• An adrenal mass

• Differences between the two glands

• Invasion into nearby blood vessels

• Changes that may be associated with Cushing’s disease, Addison’s disease, or an adrenal tumor

Hormone testing and other diagnostics are usually needed to determine whether an adrenal abnormality is producing excess or insufficient hormones.

Abdominal Fluid and Internal Bleeding

Ultrasound is highly useful for identifying fluid within the abdominal cavity.

Possible causes include:

• Internal bleeding

• A ruptured splenic or liver mass

• Trauma

• Severe inflammation

• Heart disease

• Low blood protein

• Urine leakage

• Bile leakage

• Infection

• Cancer

The appearance and location of the fluid can provide important clues, but sampling and laboratory analysis may be necessary to determine what the fluid contains.

Reproductive and Prostate Conditions

Ultrasound may also help evaluate:

• Uterine infection, including pyometra

• Ovarian abnormalities

• Pregnancy

• Testicular or retained-testicular abnormalities

• Prostate enlargement

• Prostatic cysts

• Prostate inflammation

• Reproductive-organ masses

Pyometra is a potentially life-threatening uterine infection and often requires emergency surgery.

Ultrasound Compared With X-Rays

X-rays and ultrasound are complementary rather than interchangeable.

X-rays are especially useful for evaluating:

• Bones and joints

• Fractures

• Chest and lungs

• Heart size

• Some bladder stones

• Intestinal gas patterns

• Certain foreign objects

• Overall organ size and position

Ultrasound is especially useful for evaluating:

• Internal organ structure

• Soft tissues

• The layers of the intestinal wall

• Fluid within or around organs

• Gallbladder contents

• Pancreatic changes

• Abdominal lymph nodes

• Masses and nodules

• Blood flow when Doppler imaging is used

• Real-time organ movement

Your veterinarian may recommend digital veterinary X-rays, ultrasound, or both depending on your pet’s symptoms.

What to Expect During Your Pet’s Ultrasound

An abdominal ultrasound is generally painless and noninvasive.

Before the Examination

You may be asked to withhold food for approximately 8 to 12 hours before the appointment. Food and gas within the stomach and intestines can interfere with ultrasound images.

Do not fast:

• A diabetic pet

• A very young puppy or kitten

• A medically fragile animal

• A pet receiving medication that must be given with food

unless our veterinary team specifically instructs you to do so.

Water is often allowed, but follow the instructions provided for your pet.

Hair Clipping

For the ultrasound probe to make clear contact with the skin, the hair on your pet’s abdomen will usually need to be clipped.

A small amount of alcohol and ultrasound gel may be applied to the skin. The gel allows sound waves to pass between the probe and the body without interference from air.

Positioning

Most pets lie on their back or side on a padded surface. A veterinary team member may gently hold and reassure your pet during the examination.

Dr. Quinn Bauer is a Fear Free Certified veterinarian, and our team uses gentle, low-stress handling techniques whenever appropriate.

Sedation

Many dogs and cats can have an ultrasound while awake.

Light sedation may be recommended when a pet is:

• Very anxious

• Painful

• Unable to remain still

• Experiencing breathing difficulty

• At risk of injuring themselves or the team

• Having a needle sample collected

Sedation decisions are individualized based on the pet’s health, stress level, and the procedures being considered.

Will Ultrasound Provide a Final Diagnosis?

Sometimes an ultrasound reveals a condition with a highly characteristic appearance. In other cases, it identifies an abnormality but cannot determine the precise cause.

For example:

• An intestinal wall may be thickened because of inflammation or lymphoma.

• A splenic mass may be benign or malignant.

• A liver nodule may represent inflammation, regeneration, or cancer.

• Pancreatic changes may support pancreatitis but must be interpreted with other findings.

Additional testing may include:

• Blood work

• Urinalysis

• Fine-needle aspiration

• Cytology

• Biopsy

• Endoscopy

• Surgery

• Repeat ultrasound

• CT imaging

• Specialist consultation

If tissue or fluid sampling is recommended, we will explain the reason, expected benefits, risks, and available options before proceeding.

Ultrasound-Guided Sampling

Ultrasound may be used to guide a needle toward an abnormal organ, mass, lymph node, or fluid pocket.

Possible procedures include:

• Fine-needle aspiration

• Fluid collection

• Cyst sampling

• Tissue biopsy

Sampling may provide cells or tissue for laboratory examination. However, not every abnormality can or should be sampled, and some patients may need sedation, blood-clotting tests, referral, or surgical biopsy.

Your veterinarian will determine whether sampling is appropriate for your pet.

After the Ultrasound

Most pets can return home shortly after a nonsedated examination.

If sedation was used, your pet may be sleepy or unsteady for several hours. Follow all discharge instructions and prevent climbing, jumping, or unsupervised outdoor activity until the sedation has fully worn off.

Your veterinarian will discuss:

• The ultrasound findings

• What the findings may mean

• Any immediate concerns

• Additional testing

• Medication or dietary recommendations

• Monitoring instructions

• Whether surgery or specialist care is advised

• When a recheck is needed

We will explain the findings in clear language and answer your questions before developing the next step in your pet’s care.

Frequently Asked Questions

Can my pet have an ultrasound the same day?

Often, yes. Same-day ultrasound availability depends on the schedule, your pet’s condition, preparation requirements, and whether stabilization or other testing is needed. Call (480) 488-2010 as early as possible.

Does an abdominal ultrasound hurt?

The examination itself is not generally painful. The veterinarian gently moves a probe over the clipped abdomen. Pets that already have abdominal pain may be sensitive when positioned or examined, so comfort and handling are adjusted accordingly.

Does my pet need anesthesia?

Most pets do not need general anesthesia. Some may benefit from light sedation when they are anxious, painful, unable to remain still, or undergoing a guided sample.

Why does my pet’s abdomen need to be shaved?

Ultrasound waves do not travel clearly through air trapped between the probe, fur, and skin. Clipping allows the probe and gel to make direct contact with the skin and produce higher-quality images.

Should my pet fast before an ultrasound?

Fasting is commonly recommended because food and intestinal gas can limit visibility. Follow the instructions from our team, and never fast a diabetic, very young, ill, or medically fragile pet unless specifically directed.

Can ultrasound diagnose pancreatitis?

Ultrasound can reveal changes supportive of pancreatitis, but it does not identify every case and should not be interpreted alone. Symptoms, examination findings, bloodwork, pancreatic testing, and imaging are considered together.

Can ultrasound tell whether a splenic mass is cancer?

Not reliably. Ultrasound can identify and characterize a splenic mass and look for abdominal bleeding or other abnormalities, but microscopic examination of cells or tissue is generally required to determine the tumor type.

Can ultrasound diagnose lymphoma?

Ultrasound may detect findings that raise suspicion for lymphoma and can help guide sampling. Cytology or biopsy is usually necessary to confirm the diagnosis.

What is a gallbladder mucocele?

A gallbladder mucocele is an abnormal accumulation of thick mucus and bile within the gallbladder. It can obstruct bile flow or lead to gallbladder rupture. Ultrasound is an important diagnostic tool for identifying and monitoring this condition.

How long does an ultrasound take?

The examination time varies according to your pet’s condition and the complexity of the findings. Our team will provide an estimated timeline when the appointment is scheduled.

Are ultrasound and X-rays the same?

No. X-rays are excellent for evaluating bones, the chest, gas patterns, and certain foreign objects. Ultrasound provides more detailed information about soft tissue and internal organ structure. Your veterinarian may recommend one or both.
