Veterinary Technician Exam Practice Questions

Answer: A. Computed tomography (CT scan) is the passing of a very thin x-ray beam transaxially through a patient and reconstructing images into cross sectional slices that can be viewed on a monitor. The advantages include improved radiographic contrast, spatial resolution, and cross-sectional anatomical presentation. The first scan is performed without contrast and then followed by a second scan with contrast. Sedation or general anesthesia is required for patient compliance.
