CT Scan

A CT scan — also called computerized tomography, Cat Scan, or just CT — combines a series of X-ray views taken from many different angles to produce cross-sectional images of the bones and soft tissues inside the body. The resulting images can be compared to a loaf of sliced bread. The doctor will be able to look at each of these slices individually or perform additional visualization to make 3-D images. CT scan images provide much more information than do plain X-rays. – the Mayo Clinic

 

 

CT (or Cat) Scans are a diagnostic tool used to create precise images of tissues, from bone to nerve roots. Computerized Tomography is similar to having a series of radiographs taken from various angles and then used to create a 3D cross-sectional internal image. Cat Scans are a non-invasive and non-painful means to provide more accurate diagnostics which aid the surgeon in creating a surgical plan. The scan can be done in less than one minute making scans extremely safe for your pet. Your pet will placed under anesthesia to ensure precise imaging. Once the best position has been determined, the table will move into the “Gantry”, or tubular opening in the Scanner, and xrays will be emitted from the xray tube as it spins 360° around the affected area.

 

Clinical Indications for CT:

Nasal/Sinus Disease
Helps differentiate Neoplasia from Rhinitis and guides biopsy

– Musculoskeletal Soft Tissue Tumors
Accurately shows the tumor margins for surgical and radiation planning

– Middle/Inner Ear Evaluation
determines the need for bulla osteotomy

– Skull Trauma
increased sensitivity for fracture identification and brain
hemorrhage

– Elbows
allows diagnosis of MCP fragments

– Lumbosacral Disease

– Intravertebral Disc Herniation
without the need for a Myelogram

– Thoracic Met Checks
more sensitive than radiographs

 Evaluate mediastinal and lung masses
enhances surgical planning by evaluating the extent of vascular invasion and screens for hilar metastasis

– Evaluate for Pituitary Macroadenomas
present in ~10% of pituitary dependent hyperadrenocorticism
cases

– Brain Scans
allows visualization of most brain tumors

– Ureter Evaluation
diagnosis of ectopic ureters and ureteral stones

– Orbit
differentiates between orbital wall disease processes and retrobulbar disease processes
