1. Understanding Pet Scans: An Overview
Pet scans, also known as veterinary diagnostic imaging, are non-invasive procedures that allow veterinarians to visualize the internal structures of an animal’s body. These scans are essential for diagnosing a wide range of conditions, from detecting tumors to assessing organ function and identifying injuries. Like human medicine, veterinary medicine benefits greatly from advancements in imaging technology. The decision of which scan is most appropriate depends on the pet’s symptoms, medical history, and the specific information the veterinarian needs to gather.
1.1 Why Are Pet Scans Necessary?
Pet scans are valuable tools for several reasons:
- Early Detection of Diseases: They can detect diseases in their early stages, often before any outward symptoms appear.
- Accurate Diagnosis: They provide detailed images of internal organs and tissues, helping veterinarians make accurate diagnoses.
- Treatment Planning: They assist in planning surgeries, radiation therapy, and other medical interventions.
- Monitoring Disease Progression: They help monitor the effectiveness of treatments and track the progression of diseases over time.
- Identifying Injuries: They can reveal fractures, dislocations, and other injuries that may not be visible on a physical exam.
1.2 General Preparation for Pet Scans
Before undergoing a pet scan, it’s important to follow your veterinarian’s instructions carefully. Here are some general guidelines:
- Fasting: Your pet may need to fast for a certain period before the scan, typically 8-12 hours, to ensure clear images.
- Sedation: In many cases, pets need to be sedated or anesthetized to remain still during the scan. This is to prevent movement that can blur the images.
- Hydration: Ensuring your pet is well-hydrated can help improve image quality, especially for scans involving contrast dyes.
- Medication: Discuss any medications your pet is taking with your veterinarian, as some may need to be adjusted or temporarily discontinued.
- Comfort: Make sure your pet is comfortable and relaxed before the scan. Bring a favorite blanket or toy to help ease anxiety.
1.3 Potential Risks and Side Effects
While pet scans are generally safe, there are some potential risks and side effects to be aware of:
- Anesthesia Risks: Anesthesia always carries some risk, but modern anesthetics and monitoring equipment have made it much safer.
- Allergic Reactions: Some pets may have allergic reactions to contrast dyes used in certain scans.
- Radiation Exposure: Scans like X-rays and CT scans involve exposure to radiation, but the doses are typically low and considered safe.
- Discomfort: Some pets may experience mild discomfort after the scan, especially if they were sedated.
If you have any concerns about the risks and side effects of a particular pet scan, discuss them with your veterinarian. They can provide you with more information and help you make an informed decision about your pet’s care.
2. Types of Pet Scans: A Detailed Examination
2.1 X-Rays (Radiography)
X-rays, also known as radiographs, are one of the most common and widely used types of pet scans. They use electromagnetic radiation to create images of the internal structures of an animal’s body. X-rays are particularly useful for visualizing bones, detecting foreign objects, and assessing the size and shape of organs.
- How It Works: X-rays pass through the body and are absorbed differently by different tissues. Dense tissues like bone absorb more radiation and appear white on the image, while less dense tissues like lungs appear darker.
- Common Uses:
- Diagnosing fractures and dislocations
- Detecting foreign objects in the digestive tract
- Assessing the size and shape of the heart and lungs
- Identifying signs of arthritis or other joint problems
- Benefits:
- Relatively inexpensive compared to other imaging techniques
- Quick and easy to perform
- Widely available at most veterinary clinics
- Limitations:
- Provides limited information about soft tissues
- Involves exposure to radiation, although the doses are typically low
- Preparation: Usually, no special preparation is needed for X-rays. However, your pet may need to be sedated to remain still during the procedure.
2.2 Ultrasound
Ultrasound uses high-frequency sound waves to create real-time images of the body’s internal structures. It’s a non-invasive technique that’s particularly useful for visualizing soft tissues, such as organs, blood vessels, and muscles.
- How It Works: A transducer emits sound waves that bounce off internal structures. The transducer then detects these echoes and converts them into an image.
- Common Uses:
- Evaluating abdominal organs like the liver, kidneys, spleen, and pancreas
- Assessing the heart’s structure and function (echocardiography)
- Detecting pregnancies
- Guiding biopsies and other procedures
- Benefits:
- Non-invasive and does not involve radiation
- Provides real-time images
- Can differentiate between fluid-filled and solid structures
- Limitations:
- Image quality can be affected by gas or bone
- Requires a skilled operator to interpret the images accurately
- Preparation: Your pet may need to have their fur shaved in the area being scanned. Fasting may also be required for abdominal ultrasounds.
2.3 Computed Tomography (CT) Scans
CT scans use X-rays to create detailed cross-sectional images of the body. They provide more detailed information than traditional X-rays and are useful for visualizing both bone and soft tissues.
- How It Works: A CT scanner rotates around the patient, taking multiple X-ray images from different angles. A computer then combines these images to create detailed cross-sectional views.
- Common Uses:
- Detecting tumors and assessing their size and location
- Evaluating injuries to the head, chest, and abdomen
- Planning surgeries
- Diagnosing vascular abnormalities
- Benefits:
- Provides highly detailed images
- Can visualize both bone and soft tissues

- Limitations:
- Involves exposure to higher doses of radiation than traditional X-rays
- May require anesthesia to keep the pet still
- Preparation: Your pet will need to fast for several hours before the scan. Anesthesia is usually required.
2.4 Magnetic Resonance Imaging (MRI)
MRI uses radio waves and a powerful magnetic field to create detailed images of the body’s internal structures. It’s particularly useful for visualizing soft tissues, such as the brain, spinal cord, and joints.
- How It Works: An MRI scanner uses a strong magnetic field to align the protons in the body’s tissues. Radio waves are then emitted, causing these protons to produce signals that are detected by the scanner and converted into an image.
- Common Uses:
- Diagnosing brain and spinal cord disorders
- Evaluating joint problems, such as ligament tears and cartilage damage
- Detecting tumors in soft tissues
- Benefits:
- Provides highly detailed images of soft tissues
- Does not involve radiation
- Limitations:
- Expensive compared to other imaging techniques
- Requires anesthesia to keep the pet still
- Not suitable for pets with metal implants
- Preparation: Your pet will need to fast for several hours before the scan. Anesthesia is required.
2.5 Nuclear Medicine Scans (e.g., Bone Scans, Thyroid Scans)
Nuclear medicine scans use radioactive materials to visualize specific organs or tissues in the body. These scans are particularly useful for detecting abnormalities in bone, thyroid, and other organs.
- How It Works: A small amount of radioactive material (a tracer) is injected into the pet’s bloodstream. The tracer travels to the organ or tissue being studied, where it emits gamma rays that are detected by a special camera.
- Common Uses:
- Detecting bone tumors, infections, and fractures
- Evaluating thyroid function
- Identifying sources of inflammation
- Benefits:
- Can detect abnormalities that may not be visible on other imaging techniques
- Provides information about organ function
- Limitations:
- Involves exposure to radiation
- May require special facilities and equipment
- Preparation: Specific preparation depends on the type of scan being performed. Your veterinarian will provide detailed instructions.
2.6 Positron Emission Tomography (PET) Scans
PET scans use radioactive tracers to detect metabolic activity in the body’s cells. They’re often combined with CT scans to provide detailed anatomical and functional information.
- How It Works: A radioactive tracer is injected into the pet’s bloodstream. This tracer emits positrons, which interact with electrons in the body to produce gamma rays. These gamma rays are detected by the PET scanner, which creates an image of metabolic activity.
- Common Uses:
- Detecting and staging cancer
- Evaluating brain function
- Assessing heart function
- Benefits:
- Can detect early signs of disease
- Provides information about metabolic activity
- Limitations:
- Expensive and not widely available
- Involves exposure to radiation
- Requires special facilities and equipment
- Preparation: Your pet will need to fast for several hours before the scan. Specific preparation depends on the type of tracer being used.
3. Specific PET Scan Types and Their Applications
3.1 Ga-68 Dotatate PET Scan
This newer SRS test uses a radioactive tracer called Ga-68 dotatate to bind to a tumor’s somatostatin receptors. It clearly shows NETs anywhere in the body following the injection of Ga-68 dotatate.
3.2 Copper Cu 64 Dotatate PET Scan
In 2020, the U.S. Food and Drug Administration approved a copper Cu 64 dotatate injection for use in positron emission tomography (PET) scans for certain kinds of neuroendocrine tumors (NETs). Diagnostic tracers like Cu 64 dotatate are used with PET scans and other functional imaging scans to improve how NETs are detected and staged.
- DetectnetTM: The copper Cu 64 dotatate agent, available under the commercial name DetectnetTM, is a radiopharmaceutical tracer agent used in the localization of somatostatin receptor positive NETs in adults.
- Development: Developed by RadioMedix Inc. and its commercial partner Curium, Detectnet is the first commercially available Cu 64 diagnostic agent on the U.S market.
- Clinical Sensitivity: According to phase 3 trials, Detectnet demonstrated clinical sensitivity to allow clinicians to develop more precise treatment approaches for their patients who have NETs.
- Adverse Reactions: In clinical trials, less than 2% of study participants experienced adverse reactions to the agent, which typically included nausea, vomiting, and flushing.
- Availability: After FDA approval, the CU 64 dotatate injection was immediately made available through nuclear pharmacies. Its 12.7-hour half-life allows Detectnet to be shipped throughout the US.
3.3 FDG-PET Scan (Fluorodeoxyglucose-Positron Emission Tomography Scan)
FDG-PET can find fast-growing neuroendocrine cancer cells for aggressive tumors. A small amount of FDG, a type of radioactive glucose (sugar), is injected into a vein.
- Process: The PET scanner rotates around the body and makes a picture of where the body is using glucose.
- Cancer Cell Detection: Cancer cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
- Tumor Detection: FDG is most commonly used to detect tumors that are high grade and/or poorly differentiated.
3.4 MIBG Scan
An MIBG scan is used to find certain neuroendocrine tumors, such as pheochromocytoma and paraganglioma.
- Process: A very small amount of a radioactive substance called MIBG is injected into a vein and travels through the bloodstream.
- Neuroendocrine Tumor Cell Detection: The scan detects neuroendocrine tumor cells that take up MIBG.
- Scan Duration: Scans may be taken over 1-3 days.
4. Endoscopic Procedures for Pet Diagnostics
4.1 Endoscopy
Endoscopy is a medical procedure that uses an endoscope to view the lining of multiple organs and tracts of the body.
- Endoscope: An endoscope is a flexible or rigid tube that has imaging capabilities and can enable small surgical procedures.
- Visualization: Endoscopy can be used to visualize tumors in the lungs and gastrointestinal tract (stomach, small and large intestine and rectum).
- Endoscopic Ultrasound (EUS): Sometimes an ultrasound probe is put on the end of the endoscope to perform what is called an endoscopic ultrasound (EUS), which can be particularly useful for looking at gut-adjacent organs like the pancreas.
4.2 Bronchoscopy
Bronchoscopy is a procedure to look inside the trachea and large airways in the lung for abnormal areas.
- Bronchoscope: A bronchoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples to be checked under a microscope for signs of cancer.
- Procedure: A physician inserts a bronchoscope through the nose or mouth into the trachea and lungs.
