In this study it was aimed to find the most suitable region comparing both the spread of injected material and appropriaty of the region by means of intramuscularly injections which are applied from different regions in veterinary clinics.

In tills study 16 dogs were used under two separate groups.

The dogs in the first group were injected 2 ml. of contrast medium with a 2i2 mm. long needle from the infraspinata, supraspinata, gluteal and fem.oris caudalis regions. Latero-medial radiographs of all the regions were taken and the spread of con/trast medium Was examined, after 5,15, and 30 minuteis of injections.

In the second group the dogs were injected 2 ml. of indian ink to the above mentioned regions with the same length needles.

The dolgs were euthanized after 30 minutes of injection and were kept in a deepfreeze for a day. After the end of this prioed, sections were done on the regions in order to determine the degree of spread of indian ink.

As a result it has been decided that infraspinata and gluteal regions were superior to the other regions from the point of spread of contrast medium and indian ink, and from the anatomical point of view regio infraspinata was superior to other regions.
