A 7-year-old female, Jindo dog was referred to the Veterinary Teaching Hospital with mild dyspnea and anorexia due to a gunshot trauma. The dog was wounded in the thoracic region 3 days ago. Plain radiographs showed the left 8th rib fracture, interstitial pattern in the left caudal lung field and pleural effusion. Abdominal radiographs showed the lead bullet. Computed tomographs(CT) showed the size of pulmonary contusion, laceration, lung parenchymal injuries, hemothorax and perforation of abdominal wall. The therapeutic plan was based on abnormalities seen on CT scans but not clearly seen in survey radiographs. Thoracic CT significantly provides even more informations compared with the corresponding radiographs in thoracic gunshot trauma. Although thoracic survey radiographs are useful as a screening tool, CT is highly sensitive in detecting thoracic injuries after thoracic trauma and is superior to routine thoracic survey radiographs in visualizing lung contusion, pneumothorax and hemothorax. Therefore, we recommend CT in the initial diagnostic work-up of patients with thoracic injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications.

This study describes thoracic radiographic features of normal premature minipigs at the age of 4, 8, 12 and 20 weeks. The evaluation for appearance, shape, contour, location and extent of distribution of thoracic organs was recorded through right lateral and ventrodorsal thoracic radiographs. The size of the tracheal diameter, cranial mediastinum, and the heart were measured, and information about the correlation of each organ in their thoracic conformation could be obtained. Although there were limitations with plain thoracic radiographs, basic characteristics and data for thoracic radiographs of normal premature minipigs according to each age were useful.

Although various imaging evaluation methods have been developed and utilized, thoracic radiography remains essential and is the top priority for diagnosing and managing cardiac diseases. Thoracic radiographic measurements associated with the vertebral heart scale (VHS) and caudal vena cava (CVC) can objectively diagnose cardiac disease in many animals. In particular, VHS measurement is primarily used to evaluate the dimensions of the heart size on thoracic radiographs and can measure cardiomegaly more objectively. Additionally, the value of the CVC compared with the aorta (Ao) and the length of vertebrae (VL) can be used as valuable parameters in right congestive heart failure. To describe the CVC/Ao and CVC/VL ratios in 10 long-tailed gorals (Naemorhedus caudatus) without subjective radiographic evidence of cardiac diseases. The VHS, CVC, Ao, and VL of gorals were measured in the right lateral (RL) view of the thoracic radiographs. In the RL view of 10 gorals, the VHS was 9.31 ± 0.55 vertebrae (v), the CVC/Ao ratio was 0.84 ± 0.13, and the CVC/VL ratio was 0.67 ± 0.09. Additionally, the thoracic morphology of gorals was determined to be intermediate (thoracic depth-to-width ratio, 1.04 ± 0.09, 0.75-1.25). This study confirmed that VHS was significantly correlated with CVC and Ao, and measuring and comparing each value would help diagnose cardiac diseases in gorals. The radiographic measurements in this study will allow veterinarians to diagnose several cardiac diseases in gorals.

Four dogs were incidentally diagnosed as plate-like atelectasis (PLA) by thoracic radiographs. The dogs underwent thoracic computed tomography (CT) examination with various causes. On the lateral radiographs, PLA lesions were observed as a single linear or curvilinear radiopaque area in all four dogs. Although PLA lesions were observed linear structures on dorsal and sagittal reformatted CT images as in the radiographs, it appeared pulmonary opacification or band shape on transverse images. Therefore, care should be taken to differentiate PLA from other pulmonary diseases.

A 7 years old, male, Afghan hound (case 1) and a 10 years old, castrated male, Pekingese (case 2) were referred with dyspnea. In case 1, thoracic radiographs showed moderate amount of pleural effusion and lobar sign in the left cranial lung lobe. Following computed tomographic (CT) examination, lung lobe torsion in left cranial lung lobe was diagnosed. In case 2, thoracic radiographs showed increased cranial lobar opacity but there was no evidence of pleural effusion. CT examination revealed an abrupt ending bronchus in the left cranial lung lobe. Based on the imaging diagnosis, left cranial lung lobectomy was performed in both cases. Case 1 showed increased lobar opacity and pleural effusion, while case 2 just showed less concrete evidence of lung lobe torsion on thoracic radiographs and marked severe chronic suppurative pneumonia was histopathologically confirmed. In conclusion, CT could be an important modality when atypical lung disease is suspicious.

Purpose: This was conducted to assess the need for conventional radiographs of the thoracolumbar spine for routine screening of trauma patients who revealed no spinal trauma on chest and abdominal computed tomography (CT). Methods: We performed a retrospective review of the medical records of trauma patients who underwent conventional radiographs of the thoracolumbar spine following a chest and abdominal CT that revealed no spinal trauma. Results: Two hundred seventy-five trauma patients underwent conventional radiographs of the thoracolumbar spine following a chest and abdominal CT that revealed no spinal trauma. In 274 of the cases, the thoracolumbar spine series was also negative. Conclusion: CT of the chest and abdomen is an adequate evaluation of the thoracolumbar spine in trauma patients who require routine thoracolumbar spine screening, making subsequent conventional radiographs of the thoracolumbar spine unnecessary.

A 13-year-old spayed female Miniature Schnauzer was presented with complaints of intermittent syncope. Pericardial effusion was confirmed based on the physical examination, thoracic radiographs and echocardiography. Subsequently, prompt pericardiocentesis was performed. Clinical abnormalities were immediately improved after pericardiocentesis. However, the clinical signs associated with acute collapse recurred. After the second pericardiocentesis, thoracic radiographs revealed pleural effusion, and the clinical signs resolved rapidly. The dog underwent pleural aspiration. Analysis of pleural fluid revealed almost similar features as the previous pericardial fluid. It was possible that a pericardial-pleural fistula was created during the pericardiocentesis. The pericardial and pleural effusion disappeared after the procedures.

Thoracic kyphosis is occasionally used to describe someone with accentuated thoracic curvature, hyperkyphosis is preferred since kyphosis itself refers to the normal sagittal angle of thoracic curvature. The angle of thoracic kyphosis tends to increase with age resulting in hyperkyphosis in some individuals. The persons who suffer from hyperkyphosis are at increased risk for a variety of adverse health outcomes that include musculoskeletal alteration, physical functional limitations, poor quality of life, falls, and even earlier mortality. Hyperkyphosis may develop from vertebral fractures, degenerative disc disease, either muscle weakness, decreased mobility and sensory deficits. The gold-standard orthopaedic technique for assessment of thoracic kyphosis is standing lateral spine radiographs. Other clinical measures are Debrunner kyphometer, inclinometer, flexicurve ruler, arcometer, flexible electrogoniometer and spinal mouse.

A 5-year-old castrated male domestic shorthair cat was referred for further investigation of pulmonary nodules incidentally detected on thoracic radiographs. Thoracic radiographs identified ill-defined soft tissue opacity nodules with small faint mineral opacity. Thoracic computed tomography (CT) revealed that bronchial dilation and bronchial wall thickening in bilateral cranial and accessory lung lobes. Round to ellipsoid mineralized concretions were found embedded in the intrabronchial soft tissue attenuation material. Based on radiography, CT, and cytology, the patient was tentatively diagnosed as having broncholithiasis with chronic bronchitis. This report described the CT diagnosis of broncholithiasis, which has been rarely reported in a cat.

This case study describes the imaging features of radiography and computed tomography (CT) in four small breed dogs with lung lobe torsion. The medical records, thoracic radiographs and CT images of four dogs with confirmed lung lobe torsion were retrospectively reviewed. Pleural effusion and increased lobar opacity/density were seen on all CT and thoracic radiography in all four dogs. CT revealed narrowed/collapsed bronchus in all four dogs, while this was only appreciated on one thoracic radiography. The vesicular emphysema pattern was seen on four CT but only on three radiographic examinations. The specific findings of lung lobe torsion were vesicular emphysema and a narrowed/collapsed bronchus. These findings were more easily recognized on CT than with thoracic radiographs.
