Take care when sterilizing coils to ensure a long lifespan for this critical equipment.

Hussey, of ScanMed, advises using a medical-grade hard surface disinfectant that’s non-corrosive.

For those who need to move fast and expand clinical capabilities -- and would love new equipment -- the uCT 550 Advance offers a new fully configured 80-slice CT in up to 2 weeks with routine maintenance and parts and Software Upgrades for Life™ included.

“We wipe, we don’t spray,” Hussey said. “Spraying can make parts vulnerable.”

Electrical components are especially sensitive. Make sure to avoid exposing the electrical contacts to cleaners.

“While following the suggested guidelines, make sure not to allow any cleaning or disinfecting solution to get inside any of the coils, especially around electronic parts, and make sure the coils are completely dry before returning them to service,” McClellan said.

Take steps to mitigate damage if contact with the electrical components does occur.

“If a disinfectant does come in contact with electrical contacts, it is recommended that those areas be flushed with alcohol,” Brownley said. “Some OEMs specifically deter the use of chemicals containing amines, strong alkalis, esters, iodine, aromatic or chlorinated hydrocarbons or ketones. Under no condition, should an MR coil be placed in an autoclave or industrial washer that are common means of cleaning, disinfection and sterilization in healthcare facilities.”

Most importantly, the experts stressed that when in doubt, follow the OEM’s guidelines.

Brownley stressed that it’s important that facilities chose a cleaner or disinfectant that is approved by the coil manufacturer and that the recommended processes be followed.

“A percentage of mechanical failures on MR coils can be attributed to either facilities not using an approved chemical or using an approved chemical improperly,” Brownley said.
