We describe the normal appearance of the azygos lobe on plain radiography and CT. Several findings are presented that, to our knowledge, have not been previously reported, such as the inferior prolongation of the fissure, the apparent intrapulmonary path of the right brachiocephalic vein and superior vena cava seen on the anteroposterior chest radiograph,… (More)
In this paper we describe the normal appearance of the azygos lobe on conventional radiography and CT, presenting variants that may simulate pathology on the chest radiograph. We describe the signs that allow identification of such variants and the role of CT in explaining the findings and excluding a pathological process.
Pulmonary tuberculosis (TB) is a common worldwide lung infection. The radiological features show considerable variation, but in most cases they are characteristic enough to suggest the diagnosis. Classically, tuberculosis is divided into primary, common in childhood, and postprimary, usually presenting in adults. The most characteristic radiological feature… (More)
We reviewed 40 cases of congenital malformations of the lung that were studied with both plain radiography and computed tomography (CT). We compared the CT findings with those of radiography. We found that CT was helpful in the management of these cases because it helped confirm the diagnosis, demonstrated unsuspected findings, and better depicted anatomic… (More)
Fifteen patients with active inoperable pulmonary aspergilloma underwent percutaneous injection of a special therapeutic paste of glycerin and amphotericin B. This paste was warmed just prior to injection, and filling of the lesional cavity was achieved in one session if it was possible to obtain anaerobic conditions for destruction of the aspergilloma.… (More)
We describe a new sign of traumatic herniation of the stomach. Computed tomography (CT) shows the herniated stomach as two semicircular loops separated by a band of soft-tissue attenuation somewhat resembling a sandwich. This appearance is the axial representation of the herniated stomach.
This article reviews the high-resolution computed tomography imaging features of miliary pattern, a characteristic radiologic manifestation of diffuse micronodular lung disease. The most common entities with this pattern are miliary tuberculosis, pneumoconiosis, sarcoidosis, metastases, and hypersensitivity pneumonia. According to the distribution of the… (More)
Computed tomography was performed in two patients with endobronchial lipomas. Bronchoscopy was inconclusive, but CT provided the definitive diagnosis by demonstrating fat within the endobronchial tumor.
—This paper presents the design and characterization of a preamplifier used in the electronic front-end of low-pressure gaseous secondary electron detectors. The circuit – implemented in a printed circuit board as a proof of concept – has been designed to cope with the specifications of the readout electronics used in spatial resolution measurements.… (More)
