“…Thereby, left-sided masses could be over-represented in the present study. Nevertheless, our reported mass distribution approximates those in previous studies and on necropsy (Patnaik et al 1980, Wormser et al 2016.…”

“…In contrast, ultrasound remains heavily utilised for preoperative planning in veterinary medicine. A prior report has demonstrated that ultrasound has relatively high specificity and poor sensitivity for localising hepatic masses, and that mass location influences accuracy of localisation (Wormser et al 2016). Also, it was shown that masses arising from the left or right division were more likely to be correctly localised than those arising from the central division.…”

Objectives To estimate the sensitivity and specificity of ultrasound and CT for localising solitary hepatic masses to particular liver divisions. Materials and Methods Dogs diagnosed with a solitary liver mass by ultrasound and/or CT, with surgical or necropsy confirmation within 1 month of imaging. Ultrasound reports were reviewed for mass location. CT scans were reviewed by two radiologists and mass location was determined by consensus agreement. Sensitivity and specificity were calculated for ultrasound and CT for each liver division. Results Fourteen of 71 dogs had CT only, 27 of 71 had ultrasound only and 30 of 71 had both. Location was correctly predicted in 42 of 57 dogs (74%) by ultrasound and in 37 of 44 dogs (84%) by CT. Both CT and ultrasound had high specificity for localising masses in all divisions. Sensitivity varied among divisions and was highest for left division masses. Clinical Significance The results suggest that either imaging modality is appropriate for presurgical planning. Prospective studies are recommended to help identify additional factors that may aid in determination of hepatic mass location.

“…The right and central divisional lobes are typically fused to some degree near the hilus . The right lateral and right medial liver lobes are adhered to portions of the caudal vena cava, which increases the risk of intraoperative hemorrhage during resection . The central divisional lobes (right medial and quadrate) often must be removed en bloc because of the fact that they share closely associated vasculature, and failure to do so may result in necrosis of the remaining lobe .…”

By comparison, the left divisional lobes are largely separate from each other and more mobile than the other liver lobes, with less parenchyma adjacent to the hilus, making left divisional lobectomies more surgically feasible .…”

Objective To determine the efficacy of contrast peritoneography in delineating liver lobe fissures by using computed tomography (CT). Study design Prospective cross‐sectional study. Animals Canine cadavers (n = 10). Methods An abdominal CT image of each cadaver was obtained under three conditions: without peritoneal contrast (precontrast), after insufflation of the peritoneal cavity with CO2 (negative contrast), and after intraperitoneal administration of iohexol (positive contrast). Images were reconstructed in three planes. Three reviewers independently scored each plane/contrast combination. Observers measured the length of each fissure in each plane. The measurable length of fissures was compared between techniques but was not compared with the actual length on cadavers. Results When assessment of all fissures was combined, measurements were obtained in 96 to 108 of 120 (80%‐90%) positive contrast studies, 56 to 96 of 120 (47%‐80%) negative contrast studies, and 12 to 32 of 120 (10%‐27%) precontrast CT images. All observers measured fissures in all planes that were approximately two times longer on positive compared with negative contrast studies and two times longer on negative contrast studies compared with CT images without contrast. Measurable fissure lengths were greater on positive contrast CT images (P < .0001) than on other CT images. Conclusion Positive contrast CT peritoneography improved the delineation of hepatic interlobar fissures in normal canine cadavers. Clinical significance These results justify further studies to determine the ability to locate large hepatic masses in dogs with positive CT. Positive contrast CT peritoneography may assist treatment planning in dogs with large hepatic tumors.

“…Preoperative assessment of hepatic mass lesions usually involves ultrasonography or CT, although there are few reports of the results of these studies in dogs. In a recent study of 137 dogs, ultrasonography correctly determined the site (division) of a hepatic mass in only 52% cases (Wormser et al 2016). CT enabled localisation of a hepatic mass in the right lateral lobe and facilitated complete surgical resection in a dog with hepatocellular carcinoma (Kneissl et al 1997a).…”
