A 5-y-old, intact, 2.5-kg female domestic rabbit was presented because of blood spatter on the wall of its cage and thetoenailsof its right hind limb. Physical examination revealed a red, gelatinous mass that spanned the width of the right vertical ear canal. Radiographic images revealed a soft-tissue opacity at the base of the right ear, which was superimposed over the tympanic bulla and extended to the pinna. A CT scan revealed that the soft-tissue mass was within the vertical and horizontal portions of the right external ear canal and extended to the level of the tympanic membrane, with no bony involvement...

REVIEW
Benjamin M Ellingson, Patrick Y Wen, Timothy F Cloughesy
Radiographic endpoints including response and progression are important for the evaluation of new glioblastoma therapies. The current RANO criteria was developed to overcome many of the challenges identified with previous guidelines for response assessment, however, significant challenges and limitations remain. The current recommendations build on the strengths of the current RANO criteria, while addressing many of these limitations. Modifications to the current RANO criteria include suggestions for volumetric response evaluation, use contrast enhanced T1 subtraction maps to increase lesion conspicuity, removal of qualitative non-enhancing tumor assessment requirements, use of the post-radiation time point as the baseline for newly diagnosed glioblastoma response assessment, and "treatment-agnostic" response assessment rubrics for identifying pseudoprogression, pseudoresponse, and a confirmed durable response in newly diagnosed and recurrent glioblastoma trials...

It is difficult for radiologists to classify pneumoconiosis from category 0 to category 3 on chest radiographs. Therefore, we have developed a computer-aided diagnosis (CAD) system based on a three-stage artificial neural network (ANN) method for classification based on four texture features. The image database consists of 36 chest radiographs classified as category 0 to category 3. Regions of interest (ROIs) with a matrix size of 32 × 32 were selected from chest radiographs. We obtained a gray-level histogram, histogram of gray-level difference, gray-level run-length matrix (GLRLM) feature image, and gray-level co-occurrence matrix (GLCOM) feature image in each ROI...

INTRODUCTION: Piezoelectric bone surgery is a relatively new alternative for bone-related procedures in oral and maxillofacial surgery. It represents an innovative technique as it offers the maxillofacial surgeon the opportunity to make precise bone cuts without damaging any soft tissue and providing a blood less surgical field. Correction of facial asymmetries is still a major problem in need of an adequate solution. Neurosensory damage to the inferior alveolar nerve can be an adverse effect of surgical correction of hemimandibular hyperplasia...

The common kestrel ( Falco tinnunculus ) is a common raptor found worldwide. To establish reference intervals for cardiac size by radiography, 14 adult common kestrels were evaluated clinically and with radiographs (lateral and ventrodorsal views). The cardiac width, thoracic width, distance between third and fourth ribs, synsacrum width, coracoid width, and distance between clavicle bones were measured on ventrodorsal radiographs. The ratio between cardiac width and the other 5 indices was calculated. Results showed a significant, positive correlation between the cardiac width and thoracic width and between cardiac width and coracoid width...

A 25-year-old, male mealy Amazon parrot (Amazona farinose) with a history of polycythemia, hepatomegaly, and epistaxis was evaluated for progressive lethargy and anorexia. Clinical laboratory testing revealed severe polycythemia (71%), hypophosphatemia (1.6 mg/dL), and mild hypokalemia (2.8 mEq/L). Radiographs showed marked hepatomegaly and loss of air sac space. Despite supportive treatments, the bird's condition deteriorated, and it developed ataxia, was unable to fly, and became oxygen dependent. An echocardiogram, including an air bubble study, revealed a right-to-left atrial shunt and presumed pulmonary arterial hypertension...
