Single-Use Trays and Bowls in Veterinary Scintigraphy: Where They Fit

A university team told VOLKOS that it was satisfied with the quality and durability of our litter trays and food bowls, and highlighted their usefulness in work involving scintigraphy and radioactive waste. The institution is not identified here. This is qualitative customer feedback, not an independently verified clinical study or a radiation-safety endorsement. It raises a useful question for other veterinary hospitals: where can single-use patient equipment fit in a nuclear-medicine service?

Scintigraphy changes the equipment pathway

Nuclear scintigraphy uses a radiopharmaceutical and a gamma camera to examine the distribution of a tracer in the body. UC Davis describes veterinary applications including assessment of bone, thyroid disease and kidney function. Unlike ordinary radiography, the radioactive source is administered to the patient; the service therefore needs controls for patient care and potentially contaminated supplies, not just the imaging equipment.

Virginia Tech's nuclear-medicine safety programme explicitly covers its veterinary teaching hospital and equine medical centre. It describes technetium-99m imaging in dogs, cats and horses and tells staff to consider equipment and supplies contacting the patient contaminated. For a small-animal service, litter trays, bowls and other husbandry items therefore need an agreed pathway before admission. Whether an individual item is contaminated, and how it can leave that pathway, is determined by the facility's radiation-safety procedures.

Diagnostic imaging is not radioiodine therapy

Diagnostic technetium-99m scintigraphy and iodine-131 treatment for feline hyperthyroidism are different procedures. Virginia Tech describes different safety precautions for these radionuclides. The university feedback supplied to VOLKOS does not identify an isotope, species or treatment, so we do not infer that the team performs radioiodine therapy.

This distinction matters when evaluating trays and bowls. Cornell's feline radioiodine guidance specifically identifies urine as a route of litter contamination and saliva as a route of bowl contamination. Those observations support attention to patient-contact equipment in I-131 care; they are not a description of every scintigraphy procedure. Neither hospital's local patient-release or waste-storage timings should be transferred to another service.

What single-use changes — and what it does not

A single-use tray or bowl designated for disposal does not have to be returned to the ward's reusable-equipment wash-up loop. That is the practical design difference: the hospital can allocate the item to a patient and then route it through its approved waste system rather than reprocess it for another patient. It does not make the item non-radioactive, and it does not eliminate handling during care, collection or storage.

• Patient allocation: identify which supplies belong to the patient or enclosure and keep clean replacement stock outside the contaminated return pathway.
• Waste routing: agree in advance whether trays, litter, bowls and remaining liquids need separate streams. Do not assume every item from an enclosure can go into one bag.
• Containment: use the facility's approved collection containers and any required secondary containment. A litter tray or water bowl is not automatically an approved radioactive-waste package.
• Staff responsibilities: specify who may handle, survey, store and release equipment or waste under the radiation-safety programme.

There is no VOLKOS-specific evidence presented here that single-use products reduce staff radiation dose, contamination incidents or infection rates. They also create disposable solid material: replacing reusable equipment may increase the amount requiring storage. A hospital should compare the entire pathway, not assume that disposable means less waste.

Durability matters, but fit comes first

The university feedback praised the bowls' ability to hold water. That is useful experience from a customer, not a quantified water-retention test or proof of suitability for containing radioactive liquids. The hospital should assess liquid-contact performance over its intended use period, stability in the enclosure and compatibility with its collection system.

The same feedback suggested changes to the tray entrance, a rim 2–3 cm higher to limit litter scatter, and larger sizes for large cats. These are suggestions, not announced product changes. They highlight a real procurement question: can this patient enter, turn and use the tray comfortably, and does the setup keep litter contained? A higher rim and easier access can pull in opposite directions, so patient mobility and enclosure space need to be assessed together.

Questions for a supervised equipment trial

Before introducing a new consumable, the clinical team and radiation safety officer should decide what would make it suitable for their service. A small, approved evaluation can record practical observations without claiming clinical or radiological benefits that have not been measured.

• Does the tray fit the enclosure and the intended patient population, including larger or less mobile cats?
• Do the bowls remain stable and retain their contents for the intended feeding and drinking period?
• Can used equipment be collected without conflicting with the approved segregation and liquid-waste rules?
• What quantity and volume of additional solid waste would the service need to store or transfer?
• Which observations will be recorded, and who has authority to approve the equipment and its waste pathway?

Paper is a material choice, not radioactive clearance

VOLKOS supplies paper-based trays and bowls. Their material composition does not authorise recycling, ordinary disposal, composting, burial or burning after radioactive contamination. Potentially contaminated products must remain in the facility's authorised radioactive-waste system until released under its applicable procedures, or transferred through another authorised radioactive-waste route. Any subsequent disposal must also satisfy other waste and environmental requirements.

For procurement teams, the next step is to review the current product dimensions and intended use with the clinical service and radiation safety officer, then request samples or pricing for an approved evaluation. The useful lesson from the university feedback is a potential workflow fit worth investigating — not a shortcut around nuclear-medicine controls.
