Effect of radiographic positioning on the heart shadow in dogs
Abstract:
Dorsoventral thoracic radiographs of 9 dogs were taken from 0 degree to 20 degrees to the right and to the left of a vertical line from mid-sternum to the mid-thoracic vertebrae. Certain measurements indicated that angles greater than 5 degrees from the vertical introduced significant distortions of the heart shadow and thoracic wall in some instances. A method is proposed for determining from a DV thoracic radiograph when improper positioning has produced an angulation greater than 5 degrees.
