However, limited research exists on the CE patterns of the tympanic bulla in cats with bulla effusion. This retrospective study aimed to investigate the prevalence and patterns of CE in the tympanic bulla based on the presence and severity of bulla effusion in cats. Feline head CT or brain MRI images from six institutions were analyzed. Transverse pre- and postcontrast CT and MRI images were reviewed to assess the presence and severity of bulla effusion, along with the presence, pattern, and location of tympanic bulla CE. A total of 644 tympanic bullae from 322 cats were included. Bulla effusion was detected in 105 of 644 bullae, while CE was observed in 73 of 644 bullae: 5 of 539 bullae without effusion and 68 of 105 bullae with effusion. CE was significantly more common in cats with bulla effusion, with the incidence increasing as effusion severity progressed. Focal rim enhancement, predominantly localized to the dorsal aspect of the tympanic bulla, was the most frequent enhancement pattern. In cases with mild or moderate bulla effusion, only focal dorsal enhancement was observed. However, in cats with severe bulla effusion, additional patterns, including focal ventral or lateral, complete rim, and internal enhancement, emerged. These findings suggest that both the incidence and patterns of CE evolve with the progression of bulla effusion in cats and that focal dorsal enhancement may be an early indicator.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70021"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11911501/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143650996","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}

Through abdominal radiographs, the composition of mineral radiopaque uroliths can be determined by considering many different factors; this can be complex and, as such, tailor-made for the use of artificial intelligence (AI). The Minnesota Urolith Center partnered with Hill's Pet Nutrition to develop a deep learning AI algorithm (CALCurad) within a smartphone application called the MN Urolith Application that allows for the preliminary assessment of urolith composition. The algorithm provides the probability of a urolith being composed of struvite from an image taken of an abdominal radiograph. This pilot study evaluates the accuracy of the CALCurad in the context of clinical practice. A sample population of 139 dogs was considered, and the results obtained by the CALCurad were compared with the results obtained by infrared spectroscopy analysis. Agreement between the application and quantitative analyses was 81.3%. These results suggest that the CALCurad can effectively be used to predict urolith composition in dogs, helping the clinician to decide between medical and surgical management of the patient. The use of the CALCurad is an example of the usefulness of AI in helping veterinarians make clinical decisions in patient care.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70012"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143597336","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 study describes the size and characteristics of the thyroid gland on ultrasound (US) and CT examinations in the guinea pig (Cavia porcellus) without evidence of thyroid pathology and examines the possible use of US as a routine examination for thyroid diseases. This prospective and anatomical study included 20 guinea pigs that underwent CT for dental pathologies and US for thyroid gland (TG) examination. Based on US and CT images, this study evaluated the thyroid lobe dimensions (length, height, and width) and shape. Echogenicity and homogeneity were assessed on US images, and attenuation values (HU) and homogeneity were evaluated on CT images. All animals underwent CT and US examinations under anesthesia. Thyroid lobes appeared more frequently as fusiform on CT (65%) and oval on US scans (67.5%). The attenuation values on CT scans were homogeneous. On the US scans, the TG was more frequently hypoechoic. No statistically significant differences were found between the size of the right and left thyroid lobes, both with CT and US. A statistically significant difference was found between the length values on CT and US. The US and CT thyroid gland dimensions, shape, and appearance were described. Both CT and US are useful techniques for evaluating the TG in guinea pigs.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":" ","pages":"e13455"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142476004","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}

The purpose of this prospective study was (1) to evaluate the feasibility and technique of systematic ultrasonographic evaluation of the ICJ and CCJ and (2) to describe its ultrasonographic features. Abdominal ultrasound was performed in 102 fasted dogs, free of digestive signs. The time required to identify the ICJ using a standardized method was recorded for each operator and compared among four experienced ultrasonographers (ECVDI certified and associated member ECVDI) and two previously trained ECVDI residents to evaluate the feasibility of the technique. Measurements were obtained for the ICJ wall thickness. Evaluation of the contents and peristalsis of the ICJ was recorded for descriptive purposes. The easiest way to identify the ICJ was to follow the colon proximally from the urinary bladder to the ICJ. The probe was then rotated anticlockwise and shifted slightly laterally while increasing the pressure to obtain a longitudinal section of the ICJ. The ICJ was identified in less than 2 min in 98% of cases by experienced ultrasonographers and in 86% of cases by ECVDI residents. The canine ICJ appears as a short invagination of the ileum into the colon, whereas the CCJ appears as a small opening of the colon within the cecum. This study suggests that it is possible to nearly systematically identify the ICCJ with ultrasound in dogs using the described method and provides reference values for its ultrasonographic measurements.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":" ","pages":"e13452"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142476005","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}
