A total of 27 cases, 16 meningioma and 11 glioma, were included. Post-contrast T1-weighted images were provided to five blinded image evaluators in two separate randomized sessions separated by a 6-week washout period. Evaluators were asked to rate cases as \"positive,\" \"negative,\" or \"indeterminate\" for the DTS. All dogs with meningioma were rated positive for the DTS by a majority of evaluators in each session. The sensitivity and specificity for the DTS for the first session were 95% and 89.1%, respectively. Interobserver agreement for identifying the DTS was substantial (κ = 0.74), and intraobserver agreement across the two sessions was almost perfect (κ = 0.84). These findings indicate that, whereas not perfect, the DTS is accurate and reliable in the MRI differentiation of canine meningioma from glioma.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70169"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13094398/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147723830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In people receiving radiation for head and neck tumors, existing dental disease is a predisposing factor for radiation-induced oral complications that can lead to worsening periodontal disease long-term. Periodontal disease is widespread amongst the population of senior dogs typically undergoing radiotherapy, and the aim of this retrospective cohort study was to determine if there is evidence of increased alveolar bone loss in these patients. Computed tomography scans from canine patients undergoing definitive intent radiotherapy for sinonasal tumors at a veterinary teaching hospital from 2013 to 2022 were utilized to assess alveolar bone loss in the maxillary and mandibular premolars and molars at multiple follow-up time points. As the radiation dose delivered was concentrated to the maxilla, the mandibular teeth served as a control for the expected degree of alveolar bone loss. Analysis indicated that there is an increase in alveolar bone loss over time, but that there is no difference between the mandible and maxilla. This finding provides evidence that the risk of radiotherapy worsening alveolar bone loss is low in canine patients and is the first study evaluating the relationship between alveolar bone loss and radiation-induced side effects in dogs. Continued long-term follow-up, along with similar investigations for tumors more directly affecting the oral cavity, is essential to appropriately guide patient risk assessment and prophylaxis.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70173"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13094393/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147723855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging (MRI) of the lumbar spine revealed a well-demarcated, extradural-extramedullary left lateralized mass extending from L6 to L7 vertebrae, displacing and compressing the conus medullaris and the cauda equina, including the left sciatic nerve roots. The mass was T1-weighted hypointense, T2-weighted, and STIR homogeneously hyperintense, with partial contrast enhancement. Most likely diagnosis was a malignant neoplastic process, in particular sarcoma, without excluding an inflammatory process. Surgical decompression with a dorsal laminectomy was performed, and histopathology confirmed a diagnosis of hemangiosarcoma. Thoracic and abdominal computed tomography (CT) subsequently identified pulmonary nodules, with many exhibiting well-defined margins, a peripheral ground-glass halo sign, and feeding vessel signs, features highly characteristic of metastatic hemangiosarcoma. Additional hepatic and subcutaneous nodules further supported systemic metastasis. To our knowledge, this is only the second report of an extradural-extramedullary lumbar hemangiosarcoma in a dog and the first to include complete metastatic staging using CT. In this case, associating MRI and CT was particularly informative: MRI provided detailed characterization of the spinal mass, whereas CT revealed a metastatic pattern highly consistent with hemangiosarcoma. This integration of modalities demonstrates how a common tumor may present differently in an uncommon location and how advanced multimodal imaging influenced diagnostic and staging. These findings underscore the need to consider hemangiosarcoma among differential diagnoses for extradural spinal masses and highlight the clinical value of comprehensive imaging when evaluating potentially malignant spinal lesions.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70166"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147723790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even small positioning errors may result in serious normal tissue toxicity or underdosing the tumor. Respiratory motion (resulting in tumor motion) represents a significant challenge to the delivery of SRT in some tumor types. A retrospective study of pet dogs receiving a rocuronium-sugammadex combination (ROC-SUG) as a means of inducing apnea was performed. The study included 14 pet dogs (43 treatments; 1-5 treatments per patient) undergoing SRT. A bolus of ROC was effective in preventing spontaneous breathing during treatment in 3/11 (27%) treatments and in 28/32 (88%) treatments when an ROC constant rate infusion (CRI) was given throughout treatment delivery, following the initial bolus. The median duration of apnea per treatment session was 6 min (range 4-7 min). The longest period of apnea during any treatment without interruption was 7 min. Adverse effects encountered during treatment include hypercapnia, bradycardia, and hypotension. Hypercapnia was observed in 34/43 treatments (79%). However, only 1/43 treatments (2%) resulted in bradycardia and hypotension, which were rapidly reversed. All dogs recovered rapidly following SUG with complete neuromuscular blockade reversal in a median of 1 min (range: 1-2 min), and there was no evidence of recurarization in any patient. The ROC-SUG combination, particularly when used with an ROC CRI, facilitated the induction of apnea without significant adverse effects. Future studies should use a uniform treatment protocol to confirm efficacy and patient safety.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70171"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147843546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This multicenter retrospective study aimed to characterize thoracic radiographic changes in dogs with L-R, right-to-left (R-L), and bidirectional (BID) PDA. All dogs had an echocardiographic diagnosis of PDA and underwent thoracic radiography. Qualitative radiographic evaluations assessed left heart enlargement (LHE), right heart enlargement (RHE), main pulmonary artery dilation (MPAD), aortic dilation (AD), and lung patterns. Quantitative radiographic assessments included measurements of the vertebral heart score (VHS) and vertebral left atrial size (VLAS). A total of 22 dogs were included in the study (13 L-R, 6 R-L, and 3 BID). L-R and BID shunts demonstrated a significantly higher prevalence of LHE (p = 0.002) and lower prevalence of MPAD (p = 0.002) compared to R-L shunts, consistent with echocardiographic findings. All L-R cases exhibited RHE on radiography, although echocardiography only revealed LHE. R-L shunts were associated with a higher incidence of normal lung appearance compared to L-R and BID shunts (p = 0.018) and showed only RHE on radiographic evaluation. Finally, L-R PDA displayed significantly higher VHS and VLAS compared to R-L (p = 0.01 and 0.03, respectively).

Reference values for PVV have been previously established in healthy, non-sedated dogs with reported ranges of 14.7 ± 2.5 and 18.1 ± 7.6 cm/s. PVV may be influenced by physiological and pathological factors; for example, a correlation between body weight and PVV has been documented; however, the effect of other factors is unknown. The primary aims of this prospective comparative study were to investigate the effect of standardized intravenous sedation protocol of medetomidine (2-3 µg/kg) and butorphanol (0.3 mg/kg) on PVV and to determine whether post-sedation PVV results would fall below the portal hypertension threshold of 10 cm/s. Six triplex-Doppler PVV measurements were obtained pre- and post-sedation on 15 client-owned dogs undergoing abdominal ultrasonography for conditions unrelated to primary liver disease. The mean PVV pre-sedation was 14.9 ± 3.98 cm/s and 3-min post-sedation was 10.4 ± 3.73 cm/s, representing a statistically significant reduction in PVV (p < 0.001). The mean PVV was below 10 cm/s in 3/15 (20%) dogs pre-sedation and below 10 cm/s in 9/15 (60%) dogs post-sedation. There was no effect of age, sex, or weight on PVV before and/or after sedation. Sedation with medetomidine and butorphanol caused a significant reduction in PVV at 3-min post-administration. This finding should be considered when evaluating hepatic and portal hemodynamics in dogs, as 60% (9/15) of the sedated cases with presumed normal hepatic function exhibited post-sedation PVV at levels seen with portal hypertension.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70175"},"PeriodicalIF":1.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13094395/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147723776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
