Twenty dogs with pre- and postcontrast CT exams and cytological/histological diagnosis of ovarian neoplasia were included. Five dogs presented with bilateral tumors, for a total of 25 neoplasms: 15 carcinomas (4 bilateral), 4 granulosa cell tumors, 2 poorly differentiated malignant neoplasia (bilateral), 2 luteomas, 1 teratoma, 1 dysgerminoma. In two dogs, the tumor developed from an ovarian remnant. Ovarian tumors showed variable size, lobulated shape, and precontrast heterogenous appearance. Mineral foci and/or fat components were rare, observed in teratoma, granulosa cell tumors (2), and ovarian carcinoma. Tumor type was not found to be associated with any CT features. Larger masses were more likely located in the central abdomen ventral to the ipsilateral kidney, demonstrated signs of tumor rupture, and were associated with abdominal or sternal lymphadenopathy and peritoneal effusion. A tortuous ovarian artery was constantly detectable, associated with an enlarged gonadal vein (12 cases). Related cavitary changes were peritoneal effusion (14 dogs) and sternal lymphadenopathy (7 dogs). Presumed or confirmed metastasis was reported in 9 of 20 cases, with CT evidence of transcoelomic (serosal thickening, peritoneal nodules, omental cake, implant lesions to the liver, spleen, and diaphragm), lymphatic and hematogenous spread (lungs, liver, bone, muscles, and spleen). In conclusion, the present study reports the CT features of different canine ovarian neoplasia. A tortuous ovarian artery may be useful to consistently recognize the ovarian origin of a large abdominal mass.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 1","pages":"e13476"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11649852/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142839609","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}

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.

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.

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.

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}
