This retrospective study assesses the imaging characteristics and clinical outcomes of seven cats diagnosed with this disease. Radiography, echolaryngography, and endoscopy identified laryngeal masses or thickening in all cases. Echolaryngography, utilizing an 18 MHz high-frequency probe and spatial compounding, revealed abnormalities in shape, margination, echogenicity, echotexture, and laryngeal immobility, closely aligning with endoscopic findings. Histopathology revealed neutrophilic, lymphocytic, and lymphoplasmacytic inflammation, alongside granulation tissue formation. Disease-related mortality occurred between 19 and 90 days, while long-term survivors were followed for up to 801 days. The study highlights the difficulty in differentiating inflammatory and neoplastic lesions based on imaging alone, stressing the importance of biopsy for definitive diagnosis. Echolaryngography proved to be a valuable noninvasive diagnostic tool, providing detailed insights into laryngeal structure and function. These findings support its integration into routine diagnostic protocols for feline laryngeal disease while emphasizing the critical role of histopathological confirmation. Further research is warranted to refine imaging techniques and improve diagnostic accuracy, particularly in distinguishing between inflammatory and neoplastic conditions.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70014"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143442031","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}

Quantitative comparison was performed by measuring signal-to-noise (SNR) and contrast-to-noise ratios (CNR) on the same T2-weighted (T2W), T2-FLAIR, and Gradient Echo (GRE) MR brain images in each patient (native images and after denoising) in identical regions of interest. Qualitative comparisons were then conducted: three experienced veterinary radiologists independently evaluated each patient's T2W, T2-FLAIR, and GRE image series. Native and denoised images were evaluated separately, with observers blinded to the type of images they were assessing. For each image type (native and denoised) and pulse sequence type image, they assigned a subjective grade of coarseness, contrast, and overall quality. For all image series tested (T2W, T2-FLAIR, and GRE), the SNRs of cortical gray matter, subcortical white matter, deep gray matter, and internal capsule were statistically significantly higher on images treated with DL denoising algorithm than native images. Similarly, for all image series types tested, the CNRs between cortical gray and white matter and between deep gray matter and internal capsule were significantly higher on DL algorithm-treated images than native images. The qualitative analysis confirmed these results, with generally better coarseness, contrast, and overall quality scores for the images treated with the DL denoising algorithm. In this study, this DICOM-based DL denoising algorithm reduced noise in 1.5T MRI canine and feline brain images, and radiologists' perceived image quality improved.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70015"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11822732/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143411102","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}

Preoperative diagnosis allows for more precise prognostication and surgical planning, potentially associated with improved surgical outcomes. This prospective, descriptive, anatomical study aimed to describe the anatomy of the equine CFTS using noncontrast and contrast CT in clinically normal cadaver limbs. Ten pairs of equine forelimbs free of gross external abnormalities were examined from mid-antebrachium to distal metacarpus. Specimens initially underwent noncontrast CT examination using 135 kVp, dynamic mAs, and 1 mm slice thickness. Contrast media (iohexol) diluted in saline (total 60 mL, final concentration 75 mg/mL) was injected into the CFTS from a lateral approach before the CT examination was repeated. Tenoscopy was then performed using the conventional lateral approach. Dissection was used to compare the gross, tenoscopic, and imaging findings. The combined noncontrast CT and contrast CT examinations provided excellent anatomical detail of intrathecal and extrathecal structures. Detailed anatomy of the previously undescribed proximal mesotenon and manica of the common mesotenon were also identified. The distal termination of the CFTS was beyond the mid-metacarpus in most specimens, which is significantly more distal than previously reported. This is an important consideration when administering local anesthesia in orthopedic examinations to prevent potential iatrogenic CFTS penetration, which may induce sepsis if the aseptic technique is not followed. Noncontrast and contrast CT can be used to accurately identify CFTS anatomy. Documentation of new intrathecal structures provides a greater understanding of CFTS anatomy.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70019"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11891470/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587298","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}

For part one, a single-center retrospective observational study was performed to determine the prevalence of ARSAs in a population of 1000 dogs undergoing contrast-enhanced CT for various reasons. For part two, further canine ARSA cases were collected to characterize their imaging features further and determine whether any imaging findings were more frequent in dogs with clinical signs attributed to a VRA. The prevalence of ARSA was 1.2% (12/1000). For part two, out of a total of 37 dogs with ARSA, this finding was thought to be incidental in 28 cases (75.6%), clinically relevant in 1 case (2.7%), and potentially relevant in 8 cases (21.6%). Cranial esophageal dilation with gas and fluid and esophageal compression at the site of the ARSA crossing the esophagus was found in the case where the ARSA was considered relevant. Esophageal dilation with esophageal compression by the ARSA was also more frequent in the potentially relevant group. Our study shows that an ARSA is more likely to be an incidental finding; however, due to the low number of cases where the ARSA was considered relevant, no specific imaging findings were found that could help determine their clinical relevance.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 2","pages":"e70011"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11808225/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143383321","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 horses, a renal ultrasound can be performed through the abdominal wall (TA) or transrectally (TR), being an important tool for the evaluation of the kidneys. Besides renal morphology, resistivity (RI) and pulsatility indexes (PI) may be early tools to detect renal injury as they reflect arterial compliance. Twenty-nine healthy adult horses were sonographically evaluated by TA and TR approaches, measuring RI and PI on both kidneys. The mean values from the TA for RI and PI in the right kidney were, respectively, 0.577 ± 0.072 and 0.950 ± 0.182, and 0.553 ± 0.077 and 0.884 ± 0.163 in the left kidney.

No differences (two-way ANOVA) were observed between the left and right kidneys [RI (p = .31) and PI (p = .24)] nor between techniques for both RI and PI, being relevant to state that data on the right kidney by the TR technique did not allow a reliable statistical evaluation. Obtaining good quality TR images in larger horses and satisfactory TA images in obese horses were important differences for each examination technique.

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}
