Nuclear Scintigraphy

8 Scintigraphy  page

We are equipped with a digital gamma camera for nuclear scintigraphy which allows the functional evaluation of different organs or systems. It is more sensitive to physiological changes compared to diagnostic radiology and sonography and can detect some abnormalities before they become apparent on other imaging modalities.

The most common applications are:

Thyroid Scans: These are used primarily to confirm the presence of hyperfunctional tissue in cats that are suspected to be hyperthyroid and to help evaluate the origin of neck masses in dogs.

Bone scans: Bone scans are used primarily in cases of occult lameness or to localize metastatic bone lesions. Bone scans allow us to evaluate the patient’s entire skeleton in a cost and time-efficient manner.

Less commonly performed studies include:

Portal scintigraphy: These scans offer a minimally-invasive and accurate method for detecting portosystemic shunts but do not allow us to determine the location of the shunt. The procedure consists of depositing a radionuclide (99m-Technetium) into the spleen using ultrasonographic guidance, followed by acquisition of several images over a three-minute period.

Glomerular function rate (GFR) for renal function evaluation: This allows us to accurately determine the function of each individual kidney.
