Article Synopsis
- The study evaluated the effectiveness of CT scans in identifying the locations of liver masses in dogs, finding an overall accuracy of 74.3% for lobes and 88% for divisions of the liver.
- It also noted differences in accuracy among various liver lobes, with the left lateral lobe showing the highest accuracy, while the quadrate and right lateral lobes had significantly lower accuracy rates.
- Lastly, the agreement among radiologists was generally good to excellent for divisions, but more variable for lobe localization, indicating that division-based localization is more reliable.

Article Synopsis
- This study analyzes the accuracy of four convolutional neural networks (CNNs) in evaluating canine thoracic radiographs compared to 13 veterinary radiologists, using a set of 50 radiographic studies as a reference.
- The research established a gold standard through evaluations by three board-certified veterinary radiologists, focusing on 15 specific thoracic labels, and found that the CNNs generally performed similarly, with some variations based on training methods.
- Overall, the veterinary radiologists outperformed the CNNs, showing lower error rates, particularly for five of the 15 labels, though two CNNs did excel in identifying esophageal dilation, prompting further exploration into AI's role in veterinary radiology
Objective: To determine the diagnostic accuracy of optical coherence tomography (OCT) to assess surgical margins of canine soft tissue sarcoma (STS) and determine the influence of observer specialty and training.
Study Design: Blinded clinical prospective study.
Animals: Twenty-five dogs undergoing surgical excision of STS.
Objective: To describe percutaneous microwave ablation (MWA) of presumptive pulmonary metastases and the outcome of two dogs.
Animals: Two dogs with pulmonary lesions after treatment of spontaneously occurring appendicular osteosarcoma.
Study Design: Preliminary prospective clinical study.

Gallbladder mucoceles are potentially fatal in dogs. Multiphase CT angiography was performed to evaluate the canine gallbladder in three conditions: no sludge, sludge occupying ≥25% of the lumen, and mucoceles. Twenty dogs with normal hepatobiliary bloodwork and no-to-minimal gallbladder sludge, 13 dogs with normal bloodwork and ≥25% sludge in the gallbladder lumen, and 18 dogs with histologically confirmed gallbladder mucoceles were enrolled in a prospective, observational diagnostic accuracy study.

In this retrospective, multicenter study, CT images of dogs with histologically confirmed liposarcomas were reviewed for size, location, attenuation, contrast enhancement, border definition, internal homogeneity, local infiltration, and mineralization. A total of 24 dogs with 26 liposarcomas were sampled.
