A retrospective study was undertaken to determine the prevalence of different diseases in cats referred for investigation chronic nasal disease, identify historical, clinical and diagnostic features which may assist making a diagnosis, provide information pertaining outcome these cats. Diagnoses included neoplasia (30 cases), rhinitis (27), foreign body (8), nasopharyngeal stenosis (5), Actinomyces infection (2), polyps stenotic nares subsequent trauma (1). The most common lymphosarcoma (21...

Elastography is a simple, expedient and noninvasive technique that may be used to assess the elasticity or stiffness of tissue, in conjunction with traditional B‐mode ultrasonography. Quantitative assessment tissue can made which involves measurement shear wave velocity within interest. The goal this study was feasibility elastography for clinical use abdomen conscious small animals investigate factors affect measurement. performed on liver, spleen, kidneys 15 dogs at predefined depths...

The prevalence of polycystic kidney disease was assessed in 132 Persian cats, 46 them referred for the investigation and treatment medical or surgical conditions, 86 apparently healthy cats specifically to be screened disease. Cats renomegaly renal failure were excluded, under 10 months old only included if they had been examined postmortem. One hundred twenty‐six ultrasonographically with a 7.5 MHz sector scanner, other six Forty‐nine screening (57.0 per cent) 16 clinical reasons (34.8...

Polycystic kidney disease (PKD) is the most prevalent inherited genetic in cats with Persian and Persian-related breeds predominantly affected. Diagnosis of PKD relied on ultrasound scanning until recent development gene test. However, testing has limitations as it will only identify autosomal dominant form not other forms cystic disease. Ultrasound also advantage being able to assess severity progression affected cats. The aim this study was demonstrate repeatability detection over time....

O bjectives : To make an objective assessment of the usefulness magnetic resonance imaging in diagnosis meniscal damage and cranial cruciate ligament disease canine stifle by comparing findings with surgical findings. M ethods Magnetic images 18 stifles from dogs which had undergone for investigation were reviewed. For every stifle, menisci ligaments assessed according to predetermined criteria. The compared reported sensitivity, specificity, positive negative predictive values (PPV NPV)...

This article describes the MRI features of a middle ear cholesteatoma in an 8 yr old flat-coated retriever. Physical examination revealed pain on opening jaw, and otoscopic showed tympanic membrane rupture associated with hyperplastic tissue at entrance ear. Standard sequences allowed for identification severely expanded bulla containing material that was isointense to brain T1-weighted images mixed intensity T2-weighted fluid-attenuated inversion recovery sequences. No postcontrast...

Mineralization of paraprostatic cysts is reported to be uncommon. This retrospective study was performed review the imaging findings eight histologically confirmed canine cysts. Radiographic patterns mineralization seen are described. Four dogs had mineralized on radiography not consistently ultrasonography, probably due lack acoustic shadowing artefact from small depth tissue. It thus concluded that more common than implied in literature, and superior ultrasonography identifying its presence.

Abstract An experimental and theoretical investigation of the unsteady‐state operation a pilot‐scale packed gas absorption column was made. Carbon dioxide removed from an air‐carbon mixture into aqueous monoethanalamine solution by accompanied chemical reaction. A numerical simulation contactor response to variations in feed flowrates compositions based on method characteristics, successfully predicted experimentally determined responses within range repeatability experiments.

To evaluate inter- and intraobserver reliability of the assessment computed tomography features commonly used in identification classification medial coronoid process disease to assess variability percentage ulna sclerosis from single transverse images.Eight observers, on two occasions, reviewed 84 standardised images acquired at level apex process. Observers assessed: disease, fragmentation, osteophytes, grade delineation with normal bone defined using a sclerometer. Cohen's kappa...

To describe the CT appearance of anal sac adenocarcinoma lesions in a population dogs including relations between primary tumour, and locoregional distant metastasis.Retrospective review with confirmed available images thorax, abdomen pelvis.A 70 were included study. No association was found mass size presence or absence iliosacral lymph node enlargement. The prevalence local metastatic disease characterised by lymphadenomegaly this study 71%, pulmonary metastases identified 11% cases. There...

A ismonth‐old bitch was presented for investigation of a two‐month history dysuria. Clinical signs had developed within one day routine ovariohysterectomy. rounded mass palpable in the caudal abdomen which shown radiographically to displace and compress urinary bladder. On ultrasonography, composed primarily pockets hypoechoic fluid divided by hyperechoic septae; blood obtained on fine‐needle aspiration. The surgically removed dog regained normal function few days. Histopathological...

Previous lymphangiographic studies have investigated the use of computed tomography (CT) for characterizing thoracic duct and its tributaries in dogs. However, there is limited published information on appearance canine cisterna chyli using CT. The objective this retrospective study was to describe features pre- post-contrast abdominal CT studies. presence, location, shape, maximum width, size compared with aortic diameter (Ao:cisterna ratio) mean attenuation were recorded from archived...

DIAGNOSTIC information provided by plain radiographs of the gastrointestinal tract is often limited due to relatively poor contrast between structures. The anatomically comprises oesophagus, stomach, small and large intestines, pancreas, mesentery associated lymph nodes. Contrast radiography less useful for investigation For animal practitioner, its value lies in ability provide about size, shape, position mucosal surfaces stomach aid detection many structural lesions; addition, it allows a...

Objectives The aim of the present study was to investigate whether diagnostic assessment methods used on radiographs in humans with slipped capital femoral epiphysis (SCFE) can be cats. Methods ventrodorsal (VD) extended-leg and VD frog-leg pelvic 20 cats SCFE without fully displaced epiphyses (FCE), eight FCE five control normal anatomy were assessed by observers two separate occasions 3 months apart. Klein’s line modified each radiograph, S-sign radiograph. Results Excluding cases FCE,...

The superficial supramammary lymph nodes of 54 lactating dairy cows were examined ultrasonographically with a 7.5 MHz linear transducer; each node was measured in two planes within 24 hours recording the milk somatic cell count. In most cows, well demarcated from surrounding tissue. parenchyma ranged hypoechoic to anechoic, central bright hyperechoic area, and thin line surrounded nodes. size varied, but their internal architecture remained relatively consistent. Their mean length 7.4 cm...

Abstract OBJECTIVE This study aimed to document the radiographic appearance of femoral nutrient foramina and variation this in dogs undergoing total hip replacement (THR). Our hypothesis was that foramen would be consistent with previously described anatomy, some variations. ANIMALS 89 client-owned dogs. METHODS Preoperative radiographs were retrospectively analyzed for THR at a single referral center. The signalment all recorded. Radiographs examined describe number, direction, appearance,...

The paper presents some experimental results from scheduling analysis of a task set on commercial real-time operating system using complex modeling and framework. Simple models, used in traditional techniques, are only concerned with task's execution time. Complex models examine shared resource contention varying priorities, resulting an enhanced view behavior. A series experiments VxWorks(R) generates for the tasks executing system, predicts behavior, explores limits current techniques.

The authors describe a toolset for performance-based design and analysis of distributed real-time systems. is based on their methodology, denoted pipeline scheduling, that provides set rules an engineer can follow to near-optimal, systems with fully predictable, end-to-end performance properties. methodology (1) models capturing the application, resource, system specifications; (2) algorithm figures merit evaluating design; (3) allocation scheduling algorithms navigating space find...
