Veterinary Ultrasound with The Clarius C7 Wireless Handheld Ultrasound Scanner (Part2)

Articles Tuesday, October 11, 2016

Normal parenchyma of organs, as visualized through ultrasound, compare as follows:

Marked alteration of these relationships suggests an abnormality in one or more of these organs.

Importantly: When comparing the echogenicities of the above organs, it is very important to not change gain settings or depth (or any other instrument settings), in order to obtain accurate comparisons.

The organs should be systematically scanned such that the entire organ is covered, from cranial to caudal and medial to lateral. The scanner should be moved so that each section of the organ is visualized. After completely scanning each organ, the comparative images may be taken to make sure that no abnormality is missed.

Example Protocol

A protocol should be set up such that everyone in the facility who is performing ultrasound does so in the same progression. For example:

  1. Liver is scanned first – the hepatic parenchyma, gallbladder, biliary system and vascular structures must be evaluated
  2. Move right to visualize the right kidney
  3. Move over to the spleen
  4. Spleen is interrogated systematically from its head to its tail – Because splenic position is variable the sonographer may follow it either across the midline or along the left ventral abdominal wall.
  5. Left kidney should be visualized, even if it seems unwarranted
  6. Move caudally to the urinary bladder
