Complementary projections make significant contributions to radiographic diagnosis in nasal conchae disorders. This article describes a complementary radiographic projection designed for the evaluation of the conchal sinuses and bullae in horses. Six equine cadaveric heads were used. Specimens were dissected, and openings were created in the ventral and dorsal nasal conchae for the introduction of radiopaque material. The new radiographic projection was named lateral 75° dorsal-lateral ventral oblique view. This projection was obtained with the mandibular rami resting on the imaging plate and the mandible displaced toward the side of interest (partial excursion). The X-ray beam was directed dorsoventrally, slightly angled toward the side of interest (left or right offset mandible dorsoventral view), and centered at an imaginary line connecting the tips of the facial crests. The lateral 75° dorsal-lateral ventral oblique view provided enhanced visualization and allowed correct identification of equine conchal structures. Lateral displacement of the mandible and the 75° angle of inclination to the vertical plane eliminated the superimposition of anatomical structures, facilitating radiographic image interpretation and increasing diagnostic accuracy. This complementary projection is recommended in all cases of sinonasal disorders in horses.","PeriodicalId":23581,"journal":{"name":"Veterinary Radiology & Ultrasound","volume":"66 3","pages":"e70046"},"PeriodicalIF":1.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12081783/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080832","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 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}

To date, there has been no large-scale study on ARSA in dogs and their potential clinical significance. 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}
