Radiographic features associated with 360-GDV in dogs have not been investigated. The aim of this retrospective observational study is to describe radiographic features and clinical variables in dogs affected with 360-GDV and to report agreement rates between different radiologists. We also report the sensitivity and specificity of radiographs to diagnose 360-GDV in dogs. Confirmed 360-GDV cases were retrieved, and the radiographic findings were compared with dogs presenting with gastric dilatation (GD) and 180-GDV. Images were reviewed and graded by three blinded board-certified radiologists. A total of 16 dogs with confirmed 360-GDV were identified. The median age was 10 years old (2-13 years). The sensitivity for detection of 360-GDV ranged between 43.7% and 50%, and the specificity between 84.6% and 92.1%. Interobserver agreement on final diagnosis was substantial (Kappa = 0.623; 0.487-0.760, 95% CI). The highest agreement rate was in cases of 180-GDV (87%), followed by the GD cases (72%) and 360-GDV (46%). Severe esophageal distension and absence of small intestinal dilation were the only radiographic features specifically associated with 360-GDV. A similar pyloric position was found between GD and 360-GDV. Additional radiographic variables that could help differentiate GD from 360-GDV include the degree of gastric distension and the peritoneal serosal contrast. Two cases with 360-GDV were misdiagnosed by the three radiologists as GD. In conclusion, radiographically, 360-GDV cases can reassemble GD and vice versa. Radiologists and clinicians should be aware of the low sensitivity of radiographs for the detection of 360-GDV.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":" ","pages":"e13445"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11617607/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142401472","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 this multicenter, retrospective, secondary analysis, case series study, three veterinary radiologists independently reviewed and recorded imaging characteristics of MRI studies in six dogs with histopathologically confirmed ependymoma (three intracranial and three spinal cord cases). A consensus was reached when there was disagreement on specific features. All intracranial ependymomas had forebrain location, heterogeneous signal intensity in T1-weighted (T1W) and T2-weighted (T2W) images, heterogeneous contrast enhancement, and hyperintensity in T2W images. Two ependymomas had an intraventricular location; one was intra-axial. Other imaging features included intralesional cyst-like structures, intralesional hemorrhage, and perilesional edema. Dogs with spinal cord ependymoma had intramedullary lesions located in the cervical or thoracic spinal cord. Spinal cord ependymomas were isointense and homogeneous in T1W images and hyperintense in T2W images. Lesion location relative to the central canal of the spinal cord was variable. All three spinal cord ependymomas had perilesional T2W hyperintensity and moderate, heterogeneous contrast enhancement. None of the spinal cord ependymomas had intralesional cyst-like structures. One spinal cord ependymoma had evidence of drop metastases (diffuse, leptomeningeal). MRI features of canine ependymomas overlap with those of other diseases of the brain and spinal cord. Ependymoma should be considered a differential diagnosis for dogs with intraventricular, intra-axial forebrain, or intramedullary spinal cord masses.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 1","pages":"e13477"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11649882/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142839728","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}

The sealed-source applicator tip is circular and 8-10 mm in diameter. Larger treatment fields are treated with multiple overlapping fields. The applicator cannot conform to angular extensions of irregularly shaped fields, resulting in unnecessary treatment of normal tissue, and overlapping fields can overdose in some areas. With strontium-90 sources that have high activity and thus a high dose rate, small variations in duration and position of placement can be even more consequential. This prospective investigation used radiochromic film to evaluate the dosimetry of adjacent, static, overlapping fields compared with that of the same target area treated with the applicator in continuous motion intended to achieve the prescribed exposure to all points within the target. The intent was to minimize over- and underdosed areas. Three shapes of target field were used: single 2 cm circle, curvilinear field, and cloverleaf. Application times were calculated to deliver the dose to the surface, and the procedure was repeated by four operators for qualitative evaluation (1 Gy/100 cGy to target) and four operators to generate quantitative data (5 Gy/500 cGy to target). We found significant differences between methods among operators, dependent on the number of fields, and in dose drop-off at the margin of the treated field. In almost every comparison, continuous motion was more homogenous (p ≤ .01 for standard deviation from expected dose). The continuous motion technique can be used for strontium plesiotherapy when the applicator must be held.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 1","pages":"e70004"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11747260/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143012764","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}

B-mode and color Doppler ultrasonographic examination of the PLs and infrapatellar fat pad in both hind limbs and objective gait analyses were performed on the 116 riding and trotting horses included in the study. The association between ultrasonographic findings, horse age, and movement asymmetry during the trot was then investigated. Distinct or diffuse hypoechoic regions were commonly found in the intermediate PL (24/116; 20.7%), especially in the caudal aspect of the mid-third of the ligament. The infrapatellar fat pad had a hypoechoic striated appearance in all horses except one, in which it was hyperechoic. No association was found between ultrasonographic findings in the PLs and infrapatellar fat pad and lameness.

However, differentiation of perianal tumors based on CT findings remains challenging because perianal tumors can show overlapping CT characteristics. Therefore, this retrospective, multi-institutional study aimed to identify the CT findings that can differentiate between tumors originating from the anal sacs and perianal glands in canines. Twenty dogs were included, with nine apocrine gland anal sac adenocarcinomas (AGASACAs), six perianal gland adenomas, three perianal gland carcinomas, and two perianal gland epitheliomas. The tumor CT features included the tumor growth pattern, tumor shape, cystic changes within the tumor, contrast enhancement pattern, displacement of the anus, and identification of the anal sacs. The prevalences of suspected metastatic lymphadenopathy of the iliosacral lymph centers and lung metastases were evaluated. The tumor volumes and values normalized to body weight were also assessed. The tumor growth patterns differed significantly between AGASACAs and perianal gland tumors. AGASACAs mostly showed unilateral growth, whereas perianal gland tumors mostly exhibited bilateral growth. CT features, except for the tumor growth pattern, failed to show significant differences between tumors arising from the anal sacs and those arising from the perianal glands. Although histopathological diagnosis remains the gold standard, this study's findings suggest that CT analysis of tumor growth patterns may help differentiate AGASACAs from perianal gland tumors.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":" ","pages":"e13453"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142475999","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 prospective, descriptive study was to describe radiographic, computed tomographic, and histologic characteristics of bone for a group of clinically normal laying hens housed in conditions comparable to those of backyard flocks. Sixteen 60-week-old Lohmann Brown laying hens were included. Hens were housed in a free-range unit with outdoor access at a university research and teaching farm. Hens were defined as clinically normal by the farm manager and a veterinary researcher in laying hen behavior and welfare. Findings from the horizontal beam, left lateral, sternal radiographs (n = 16), postmortem, and whole-body CT scans (n = 4) were recorded by a veterinary radiologist and a research technician. Histologic findings for sternal, femoral, and tibiotarsal bone samples (n = 5) were recorded by a veterinary pathologist. The most frequent radiographic findings for the sternal carina (keel bone) were smoothly marginated concave deviations of the ventral margin and caudal section fractures. Multiple punctate mineral opacities (PMOs) were present in radiographs and CT images for all hens and were involved in the sternal carina and multiple other bones in the axial and appendicular skeleton. No bone abnormalities were identified in any histologic sections where PMOs were radiographically detected. Authors propose that PMOs are normal radiographic and CT findings in the bones of mature, laying hens and may represent temporary calcium reservoirs formed during osteoclastic activities.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":" ","pages":"e13443"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11617609/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366717","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}

Radiographs are performed to measure the tibial plateau angle (TPA) for planning tibial plateau leveling osteotomy (TPLO) surgery. Concomitant damage to other intra-articular structures, for which clinical detection is unreliable, may occur and potentially affect the surgical outcome. Joint assessment during TPLO through instrumented inspection is therefore advised, though it increases the risk of complications. Magnetic resonance imaging offers a noninvasive alternative, adds information about intra- and periarticular structures, and could potentially be used for TPA measurements. This prospective study aimed to (1) assess the correlation between the TPA measured with the standard presurgical radiographs and with a single sagittal intermediate-weighted fat-saturated MRI sequence and (2) compare the surgical findings with the information obtained by the MRI sequence. Twenty-one stifles were included; TPA correlation using radiographs-MRI was available for 17 stifles, and surgery-MRI comparison was available for 18 stifles. A strong significant correlation was identified between the TPA measurements on radiographs-MRI (Pearson correlation coefficient 0.923; p-value <.0001). The sensitivity and specificity of MRI to detect surgically confirmed complete versus partial CCL rupture were 85.7% and 75%, respectively; MRI identified 7 of 8 surgically confirmed injured menisci and detected abnormal signal intensity in 8 of 10 medial menisci and nine caudal cruciate ligaments reported as normal intra-operatively. The MRI additionally identified abnormal subchondral bone signals in nine stifles and muscular hyperintensity in six cases. This presurgical MRI sequence might replace standard radiographs for TPA measurements and can provide information about concomitant joint injuries with potential prognostic impact.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 1","pages":"e70005"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142955512","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}
