Nuclear medicine (diagnostics and therapy)

Scintigraphy is a medical imaging technique that uses radioactive substances (isotopes) and is used when traditional medical imaging (X-rays, CT, ultrasound) does not provide sufficient information about an animal's problem or disorder.

The substances are harmless for your animal and the radiation load is minimal. The radioactive particle loses its radiation after a period of time. This is called half-life.
The technique is very sensitive so it can visualize problems at a very early stage. Another advantage of this technique is that it can often give an image of the entire animal which is not that obvious with other techniques. The results in scintigraphy are often combined with other medical imaging techniques to come to a correct diagnosis.

Scintigraphy is recommended for:

• hyperthyroidism in cats: cats often have an overactive thyroid gland at a middle or advanced age that produces too many thyroid hormones. Often benign tumours cause hyperthyroidism, but the cat's general health suffers from the surplus of hormones. Although there are different medical treatments, treatment with radioactive iodine (which is also carried out in humans) is considered the best for hyperthyroidism.
• hypothyroidism in dogs - when the thyroid gland functions too slowly (when blood examination doesn't provide a correct diagnosis).
• thyroid tumours. Some patients also benefit from treatment with radioactive iodine. This is a therapy that is carried out in our clinic.
• limping
• tracing a portosystemic shunt (abnormal blood vessel in the liver).
• visualizing the activity of each kidney separately.
