Contributor(s): Vetstream Ltd, Anna Meredith, David Perpinan

Introduction

Uses

  • For use in the investigation of:
    • Liver:
      • Jaundice.
      • Unexplained raised liver enzymes. 
      • Abnormal appearance of liver on ultrasonographic examination.
      • Diffuse liver disease Liver: disease (inflammatory, infiltrative, neoplastic). 
      • Mass lesions.
    • Kidney disease Kidney: disease:
    • Intestine: mass lesions.
    • Thorax: mass lesions of chest wall, mediastinum or lung.
    • Lymph nodes: lymphadenopathy.

Advantages

  • Low cost. 
  • Minimally-invasive. 
  • Rapid. 
  • Straight forward in hands of experienced operator. 
  • Short time requirement.

Disadvantages

  • Requires patient's coat to be clipped.
