What is Advanced Imaging?

Advanced diagnostic imaging is a term used to refer to imaging modalities such as magnetic resonance imaging (MRI), computed tomography (CT scan), and nuclear medicine imaging procedures (such as proton emission tomography or PET scan). Similar to a loaf of bread cut into 1-3 mm slices, these modalities can provide a higher level of detail of anatomic structures in multiple planes. 3D images are often created from the scans.

Here in Alaska, we have both MRI and CT capabilities. These modalities are frequently recommended, and sometimes required, before pursuing certain surgical procedures. The decision on whether to choose an MRI or CT is multi-factorial and can depend on the anatomical location of interest, the suspected diagnosis, what questions are needing to be answered by the imaging, your pet’s size, breed, and overall health status, accessibility to the imaging facility, and finances. All pets need to be anesthetized, or heavily sedated, during the imaging process to prevent excessive movement. 

A surgeon will often use advanced imaging to help guide the decision on whether surgery is the best answer for your pet. These images can also significantly aid in the surgical planning process, thus improving the overall success of surgery. For oncological cases, details relating to tumor location, margins, invasiveness, and metastasis can guide expectations for overall prognosis and survival time.
