Therefore, the present study was planned with the objective of establishing baseline echocardiographic reference values for aortic cusp diameters in healthy dogs and to evaluate cusp remodeling associated with SH. Echocardiographic measurements were performed in 46 healthy dogs (26 large breed, 20 small-medium breed) and 80 clinically ill dogs, classified according to systolic blood pressure (BP) as normotensive (≤139 mmHg), prehypertensive (140-159 mmHg), hypertensive (160-179 mmHg), or severely hypertensive (≥180 mmHg), with 20 animals in each group. Two-dimensional echocardiography was used to assess left (LAC-d), right (RAC-d), and noncoronary cusp diameters (NCC-d); mean cusp diameter; and aortic root dimensions (diameters at aortic annulus, sinus of Valsalva, sino-tubular junction, and proximal ascending aorta). Cusp asymmetry was determined using an asymmetry index (≥10% variation) and subjective variation (≥2 mm). Hypertensive dogs demonstrated enlargement of all cusps compared with controls, with cusp diameters correlating positively with systolic BP (LAC-d: r = 0.39; RAC-d: r = 0.37; NCC-d: r = 0.33; p < 0.001). The LAC-d and RAC-d exhibited the best diagnostic performance (sensitivity 80%-82.5%, specificity 76.9%-78.6%). Hypertensive dogs also had increased cusp asymmetry, particularly RAC asymmetry in severe hypertension (40% vs. 10.9% in healthy dogs; p = 0.004). Sinus of Valsalva diameter was the strongest predictor of cusp enlargement. Echocardiographic measurement of aortic cusps provides novel reference values for healthy dogs and demonstrates hypertension-associated cusp remodeling. The LAC-d and RAC-d are reliable markers for identifying and monitoring hypertensive cardiac changes.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70165"},"PeriodicalIF":1.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147663208","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}

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":1.2,"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":1.2,"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}

Anecdotal observation at the authors' institution suggests that patients receiving maropitant citrate occasionally display sonographic and radiographic signs of diffuse functional ileus. The goals of this prospective one-group pretest, posttest study were to determine if administration of maropitant citrate caused changes in ultrasonographic wall thickness and peristaltic rate at the pylorus, duodenum, or jejunum and/or a radiographic change in intestinal diameter or appearance. Twenty-one healthy adult dogs (ages 1-8 years) were recruited. After overnight fasting, abdominal radiographs and a brief gastrointestinal ultrasound were performed at time 0 (baseline), followed by a 1 mg/kg subcutaneous dose of maropitant citrate. Imaging was then repeated 1 and 3 h post maropitant administration. Peristatic contractions and wall thickness at the pylorus, duodenum, and jejunum were measured with ultrasound, and radiographs were assessed for signs of functional ileus (mild diffuse dilation of the small intestine or mild increase in overall small intestinal gas content). Significant decrease in rate of peristalsis of the pylorus (p < 0.001, hp2 = 0.48) between 0 and 1 h and between 0 and 3 h and jejunum (p < 0.02, hp2 = 0.48) between 0 and 1 h was found after administration of maropitant citrate.

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). In conclusion, this study provides a detailed characterization of the thoracic radiographic alterations associated with PDA, highlighting differences based on the type of shunt and their correlation with echocardiographic findings.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"67 3","pages":"e70164"},"PeriodicalIF":1.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147723770","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}
