Video clip WB71 showing a classic positive for free intra-abdominal fluid at the HR view.  Note the black triangulation in between loops of small intestine. The HR view is called the “Home Run View” because it completes the AFAST exam and in higher fluid scoring dogs and cats will be the site for abdominocentesis because ultrasound cannot characterize the type of free fluid (only fluid sampling and testing can).  From experience, it is uncommon for the HR view to be the only positive site during AFAST.  The most common low-scoring sites are in fact the DH and CC views.
