Question 2

Which of the following describes the primary mechanism by which computed tomography (CT) produces images?

Accepted Answer

Generation of images by passing a narrow beam of X-rays through the patient from multiple angles and reconstructing cross-sectional slices.

Answer

Detection of radiofrequency signals emitted from hydrogen protons after exposure to a strong magnetic field.

Answer

Measurement of sound wave reflection from tissue interfaces.

Answer

Visualization of metabolic activity and perfusion using radioactive tracers.

Question 3

A 4-year-old female intact Maine Coon cat presents with a chronic history of intermittent vomiting and weight loss. Abdominal radiographs show generalized small intestinal distention with plication, and a linear foreign body is suspected. Which of the following diagnostic imaging modalities would be most sensitive for confirming the presence and extent of a linear foreign body and associated intestinal damage?

Accepted Answer

Abdominal ultrasonography

Answer

Plain abdominal radiography (lateral and ventrodorsal views)

Answer

Upper gastrointestinal (GI) barium contrast study

Answer

Computed tomography (CT) of the abdomen

Question 4

Regarding histopathology, what is the primary purpose of performing a biopsy of a mass rather than a fine needle aspirate (FNA)?

Accepted Answer

To provide architectural information of the tissue, which is crucial for tumor grading and determining invasiveness.

Answer

To obtain a larger sample size, allowing for more comprehensive immunohistochemical staining.

Answer

To reduce the risk of tumor cell seeding compared to FNA.

Answer

To allow for immediate intraoperative diagnosis.

Question 5

Which imaging modality is most suitable for evaluating dynamic joint function, such as patellar luxation or joint instability, in real-time?

Accepted Answer

Fluoroscopy

Answer

Magnetic Resonance Imaging (MRI)

Answer

Computed Tomography (CT)

Answer

Scintigraphy

Question 6

A pathologist observes numerous multinucleated giant cells, epithelioid macrophages, and central caseous necrosis within a lymph node biopsy from a goat. Which of the following pathological processes is most strongly indicated by these findings?

Accepted Answer
