Questions and Answers

Which imaging modality is quick to obtain the images once in the machine, but slow to prep the patient and obtain a final report from a radiologist?

  • CT (correct)
  • Radiography
  • Ultrasound
  • MRI

What can happen if a dog is put onto its back during imaging?

  • Increased stress due to sedation or restraint
  • Compression of healthy lung leading to possible death
  • Compression of caudovena cava leading to reduced cardiac output (correct)
  • Increased cranial pressure leading to blood pooling in the cranial cavity

Which imaging modality has higher sensitivity and specificity than Ultrasound/radiography for detection of free fluid or gas, as well as organomegaly?

  • Ultrasound
  • Radiography
  • MRI
  • CT (correct)
