Background: Geographical Information System (GIS) is used in analyzing and displaying referenced information. GIS applications have never been reported in Veterinary Imaging. Aim: To develop a GIS-based vertebral canal (VC) map useful for spatial evaluation of extruded disc herniation (EDH) in dogs. Methods: A GIS software (ArcGIS®) was used to create 2D and 3D maps in which VC surface was divided in polygons by lines representing the latitude and longitude. Depending on dislocation, EDH could be localized in one of the above regions. The actual dislocations of herniated disc material were assessed using a series of CT studies. Choropleth maps were realized based on frequency of EDH dislocation. Results: A cylindrical model of the VC with 78 latitudinal and 8 longitudinal lines dividing 624 polygons was created. Dislocation of EDH was assessed in 142 dogs with 177 EDH. Most of EDHs were located on the transitional regions (cervico-axial; cervico-thoracic; thoraco-lumbar; lumbo-sacral) at level of ventro-cranial and ventro-central polygons. Discussions: choropleth maps highlighted both the distribution and the dislocation pattern of EDH throughout the VC. Conclusion: GIS proved to be a valuable tool in analyzing dog's EDH. Further studies are required for biomechanical analysis of EDH's dislocation pattern.

Abstract
Background: Geographical Information System (GIS) is used in analyzing and displaying referenced information. GIS applications have never been reported in Veterinary Imaging. Aim: To develop a GIS-based vertebral canal (VC) map useful for spatial evaluation of extruded disc herniation (EDH) in dogs. Methods: A GIS software (ArcGIS®) was used to create 2D and 3D maps in which VC surface was divided in polygons by lines representing the latitude and longitude. Depending on dislocation, EDH could be localized in one of the above regions. The actual dislocations of herniated disc material were assessed using a series of CT studies. Choropleth maps were realized based on frequency of EDH dislocation. Results: A cylindrical model of the VC with 78 latitudinal and 8 longitudinal lines dividing 624 polygons was created. Dislocation of EDH was assessed in 142 dogs with 177 EDH. Most of EDHs were located on the transitional regions (cervico-axial; cervico-thoracic; thoraco-lumbar; lumbo-sacral) at level of ventro-cranial and ventro-central polygons.
