ABSTRACT Feline hyperthyroidism is an endocrine disorder that is common in senior cat populations . Advances in diagnostics and treatment modalities have extended the range of treatment options available to owners of a hyperthyroid cat .
Radioactive iodine therapy ( RAIT ) is an increasingly popular choice . However , this treatment must be delivered with caution to minimise the risk of radiation exposure to veterinary personnel and the public .
There is increasing recognition of the need for safe procedures when working with radiation in veterinary settings , considering the broader range of radiationrelated services available for veterinary patients .
Part 1 of this two-part series focuses on RAIT . It will outline the benefits and risks of the treatment , the terminology used to describe radiation doses and how they are measured , and radiation safety principles , including examples of their implementation at a dedicated RAIT clinic in Melbourne , Australia .
Part 2 ( p . 41 – 46 ) will look at the process of treating cats at the abovementioned RAIT clinic , including referral and hospitalisation . It will also briefly outline recommendations for post-treatment monitoring and advice for owners on caring for the patient at home .
