A patent ductus venosus (PDV) is an interlobar shunt that arises from the left portal branch and traverses the ligamentum venosum fissure (LVF) between the left lateral liver lobe and the papillary process of the caudate liver lobe. Identifying the LVF may aid in PDV diagnosis during ultrasonography. In this prospective exploratory study, the ultrasonographic appearances of the LVF and adjacent structures were described in 24 dogs without hepatobiliary disease. Four intercostal acoustic windows were used, two on each side of the dog, and detectability of the following structures was recorded: aorta, left portal branch, caudal vena cava, papillary process, LVF, left lateral hepatic lobe, and ligamentum venosum. All structures were found in each dog from at least one window, with varying frequencies of detection per window. At least one window provided dynamic observation of the left lateral liver lobe, LVF, papillary process, and caudal vena cava aligned left to right, craniodorsal to and parallel with the long axis of the left portal branch. Probe placement on the left hypochondriac region (left dorsal to the xiphoid process) provided the best window, followed by the right hypochondriac region. More dorsal windows (costal regions) were less useful, especially on the left. The LVF was visible in all dogs (100%) from the left hypochondriac window and in 19 dogs (79%) from the right hypochondriac window, justifying further investigation in dogs with intrahepatic portosystemic shunts.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70018"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11867981/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143524716","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}

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}

The objective of this retrospective observational study was to describe a series of dogs diagnosed with PFSSCC and report their response to radiation therapy. Medical records of dogs with a diagnosis of PFSSCC were reviewed. Data collected included signalment, presenting complaint, clinicopathologic and diagnostic imaging findings, treatment, therapeutic response, and date of death or last follow-up. Eight cases of PFSSCC in dogs were treated with radiation therapy at the authors' institution. Three of these dogs were treated with coarse-fractionated radiation therapy. One dog was euthanized due to an unrelated cause 36 months after completing the radiation therapy. The second and third dogs survived 18 and 3 months, respectively, from the end of treatment to death due to PFSCC. Five further dogs were treated with a more fractionated protocol (Monday-Wednesday-Friday schedule). The median survival time for all patients was 7.5 months (range 2-36 months). Despite the small number of cases and variation in the radiation protocols used, the treatment outcomes in these eight dogs suggest that radiation therapy is potentially a viable treatment option for dogs with PFSSCC and that coarse fractionation might be an appropriate approach if more finely fractionated protocols are not possible.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 1","pages":"e70000"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11701348/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932676","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}
