Thorax radiography examination in pediatric patients is one of the most frequent examinations because many abnormalities that occur thorax and have a high probability at children's age. Pediatric are assisted by companion from adult patient's family. Calculation measurement radiation dose received very important as they room with patient during imaging process. And no matter how small companion...

The distribution and speciation of arsenic (As) were analyzed in individuals of various life stages of a midge, Chironomus riparius, and the mosquito Culex tarsalis exposed to 1000 μg/l arsenate. X-ray absorption spectroscopy (XAS) revealed that C. riparius larvae accumulate As in their midgut, with inorganic arsenate [As(V)] being the predominant form, followed by arsenite [As(III)] and an As-...

Spontaneous acute pneumothorax may occur as a result of spontanous rupture of subpleural blebs or bullae and it is extremely rare during pregnancy. Spontaneous acute pneumothorax and pneumomediastinum were diagnosed in a young pregnant woman admitted with the complaints of swelling and pain on her neck and upper thorax following 2 days' dyspnea. Nasal oxygen, analgesics and antiemetics were use...

The ribs are essential structures of the osseous thorax that provide certain significant information and aid interpretation of radiologic images in daily routine practice. Intrathoracic rib is a rare congenital anomaly that is usually discovered incidentally, but may cause in vain interventions in case of being unaware. We herein report an intrathoracic rib in a girl whose chest X-ray was stran...

Radiotherapy to the thorax in conventional dosage appears to be capable of causing damage to any of the tissues in the thoracic wall or within the thoracic cavity. Since the earliest days of x-ray treatment radiation changes in the skin have been such an everyday problem that they scarcely warrant discussion here except to note that with the advent of new radiotherapeutic techniques they are be...

A patient presented with recent onset of increasing shortness of breath, weight loss and low-grade fever. His chest X-ray revealed bilateral miliary shadowing. He was investigated with CT-scanning of thorax. Later, a biopsy from supra-clavicular node and its immunocytochemistry studies confirmed metastasis from primary lung cancer. Primary lung cancer with miliary pulmonary metastases is a rare...

An arc welder of 32 years of age is presented with a random finding of miliar reticulonodular shadows in the plain film of the thorax. Subjectively and objectively the patient appears healthy. The presence of a pneumoconiosis is confirmed by biopsy. Differential diagnosis had to consider sarcoidosis and pulmonary siderosis in view of the known professional anamnesis. This case report underlines...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...

Ganglioneuroblastoma, nodular (GNBn) is a subtype of neuroblastic tumors. This is a rare malignancy typically affecting young children. Few cases are reported in adolescents and adults. The prognosis is related to the surgical excision radicality. Hereby we present a case of a young male patient age 13 from the Horn of Africa presenting with vague symptoms of fatigue and weight loss. Chest X-r...

Understanding the movement of tumors caused by respiratory motion is very important for conformal radiatherapy. However, respiratory motion is very difficult to study by conventional x-ray CT imaging since object motion causes inconsistent projection views, leading to artifacts in reconstructed images. We propose to estimate the parameters of a nonrigid, free breathing motion model from a set o...
