This module of the vet-Anatomy veterinary atlas concerns the abdomen and pelvis of the dog in CT.
CT images are from a healthy 6-year-old castrated male dog.
In this module of the animal atlas vet-Anatomy is displayed the cross-sectional labeled anatomy of the canine abdominal cavity and the pelvis on a Computed Tomography (CT) and on 3D images of the abdomen of the dog.
CT images are available in 3 different planes (transverse, sagittal and dorsal) with two kinds of contrast (soft tissues/vessels and bones). Additional 3D anatomical images are available on the end of module, for a better understanding of gross anatomy of the dog, displaying 3D volume rendering of bones, splanchnology (liver, spleen, pancreas, digestive tract), urogenital system, arteries, systemic venous system (mainly caudal vena cava and its branches), portal venous system, muscles, and surface anatomy.
834 anatomical parts have been labelled, available in different sections (filters):
This computed tomography with injection of iodinated contrast agent was performed on a healthy 6-year-old castrated male dog (Labrador Retriever) by Dr. Susanne AEB Boroffka, dipl. ECVDI, PhD (Utrecht, Netherland).
3D Volume Rendering images were created from the same CT dicom data by the Dr. Antoine Micheau, on a GE ADW.
Images displaying, anatomical labelling and anatomical definitions were created by Dr. Antoine Micheau, Radiologist (Montpellier, France) and Dr. Denis Hoa, Radiologist (Montpellier, France).
Terms are labelled using the Latin terms defined in the Nomina Anatomica Veterinaria (Sixth edition - 2018 by ICVGAN). They were translated from latin to english and french by Antoine Micheau - MD, Imaios.
Anatomical notes form the authors :
In dogs the segmentation of the liver is described with four lobes and four sublobes as well as two processes, based on anatomical consideration. This is the nomenclature used on the NAV.
For some authors, the use of a vascular anatomy of canine hepatic venous system based on the analogies between Couinaud’s segmentation of the human liver and the vascular anatomy of canine liver, could be less confounding and, therefore, more useful for the surgical (and also radiological) approach to this organ.
In vet-Anatomy, we used the publication of L. Mari and F. Acocella to provide an hepatic segmentation of the dog: the canine liver lobes and human liver segments appear comparable so we use the terminology adapted from the human terminologia anatomica :
|Section||Division||Lobe||Conventional nomenclature in the NAV||Proposed segment numbering||Proposed nomenclature||Equivalent segment in human|
|Left||Left||Left lateral||Lobus hepatis sinister lateralis||
|Segment II – Left lateral hepatic lobe||
Left posterior lateral segment; Segment II
|Left medial||Lobus hepatis sinister medialis||III||Segment III – Left medial hepatic lobe||
Left anterior lateral segment; Segment III
|Central||Quadrate||Lobus quadratus||IV||Segment IV – Quadrate lobe||
Left medial segment; Segment IV
|Right medial||Lobus hepatis dexter medialis||V||Segment V – Right medial hepatic lobe||Anterior medial segment; Segment V|
|Papillary process of caudate lobe||Processus papillaris||I||Segment I – Papillary process||
Posterior segment; Caudate lobe; Segment I
|Right||Right||Right lateral||Lobus hepatis dexter lateralis||
|Segment VI – Right lateral hepatic lobe||
Anterior lateral segment; Segment VI
|Caudate process of caudate lobe||
|VII||Segment VII – Caudate process||
Posterior lateral segment; Segment VII
No segment VIII in dog
Posterior medial segment; Segment VIII
