Introduction

  • Diagnostic imaging is essential in the work-up of cats with abdominal disease.
  • Traditionally, abdominal imaging work-up was done with survey and upper GI Barium contrast radiography or ultrasound.
  • Computed tomography allows complete assessment of the abdominal and pelvic cavity, as well as thorax and other body parts within a few minutes.
  • Computed tomography uses ionizing radiation, therefore particular health and safety measures apply.

Uses

  • Acute abdominal pain Acute abdomen: investigation.
  • Investigation of palpated abdominal mass lesion.
  • Hemoabdomen, uroabdomen, ascites.
  • Hypoglycemia.
  • Polyuria and polydipsia.
  • Elevated bile acids.
  • Jaundice.
  • Staging for metastatic disease.

Common conditions in the abdomen diagnosable with CT

Advantages

  • Detailed assessment of the entire abdomen and pelvic cavity.
  • Not as operator dependent as ultrasound.
  • Gastrointestinal gas does not interfere with diagnosis as in ultrasound.
  • Can be done under sedation only or even without sedation in a restraining device with modern CT units.

Disadvantages

  • Expensive equipment that requires 3-phase power supply, dedicated room.
  • Emits ionizing radiation, patients cannot be handheld by personnel.
  • Patients need to be safely constrained, usually requires at least sedation. Restraining devices are ideal but are currently not widely available.
