Objective To evaluate the preference of observers for image quality of chest radiography using the deconvolution algorithm of point spread function (PSF) (TRUVIEW ART algorithm, DRTECH Corp.) compared with that of original chest radiography for visualization of anatomic regions of the chest. Materials and Methods Prospectively enrolled 50 pairs of posteroanterior chest radiographs collected w...

Miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner’s pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and so...

BACKGROUND Airway collapse is a common finding in dogs with chronic cough, yet the diagnosis can be difficult to confirm without specialty equipment. HYPOTHESIS Bronchoscopic documentation of tracheobronchial collapse will show better agreement with fluoroscopic imaging than with standard radiography. ANIMALS Forty-two dogs prospectively evaluated for chronic cough. METHODS In this prospe...

BP = 160/90 mmHg in upper limbs, there were no palpable pulses in lower limbs. Systolic impulse verified in the 5th left paraesternal intercostal space, where a tremor irradiated until the 2nd right paraesternal intercostal space. A rude mesotelesystolic murmur audible in that region, irradiating to cervical, subclavicular and interscapular regions. The diagnostic hypothesis was infectious endo...

A 69-year-old man with an history of liver cirrhosis complicated by hepatocellular carcinoma treated by chemoembolization, moderate mitral insufficiency and chronic atrial fibrillation presented with a rounded calcified opacity in right upper abdomen at chest radiography. Abdominal computed tomography scan showed an omogeneous and complete uptake of lipiodol within the hepatocellular carcinoma,...

Methods and materials A retrospective study of 170 asymptomatic adolescent volunteers was performed and all of them had the standing whole-spine lateral radiography. All subjects were divided into 3 groups by age: Group A (10-12 years), Group B (13-15 years), and Group C (16-18 years). Four different radiographic parameters were measured: lumbar lordosis (LL, L1-L5), thoracic kyphosis (TK, T4-T...

A 70-year-old woman with a history of motor vehicle versus train accident, previous thoracic and lumbar fusion, and recent cervical fusion was admitted for severe upper back pain, difficulty with balance, weakness of lower extremities, and progressive kyphosis. On examination, the patient was found to have diffused myelopathy and paraparesis throughout her lower extremities. She requires a walk...

A 21 year old Chinese female was found to have a thoracic tumour on routine chest radiography. At operation, the tumour was observed to arise from the left sixth rib and was adherent to the underlying pleura. It was excised with the rib. Histological sections showed a lesion composed of foci of cartilage al ternat ing with sheets of malignant spindle cells. In areas , a marked haemangiopericyto...

Chest tomosynthesis is a relatively recently introduced technique in healthcare, which produces section images of the chest at a lower radiation dose than computed tomography (CT) and with better depth resolution than conventional chest radiography. The primary aims of the studies described in this dissertation were to compare chest tomosynthesis with conventional radiography, to evaluate the e...
