Members of the Fleischner Society compiled a glossary of terms for thoracic imaging that replaces previous glossaries published in 1984 and 1996 for thoracic radiography and computed tomography (CT), respectively. The need to update the previous versions came from the recognition that new words have emerged, others have become obsolete, and the meaning of(More)
PURPOSE To analyze the influence of collimation on identification of segmental and subsegmental pulmonary arteries on spiral computed tomographic (CT) scans. MATERIAL AND METHODS Contrast material-enhanced spiral CT scans were retrospectively analyzed. Patients in group A (n = 20) underwent CT with 3-mm collimation, 1.00 second per revolution, and pitch(More)
PURPOSE To retrospectively evaluate the long-term results of transcatheter embolotherapy of pulmonary arteriovenous malformations (PAVMs) with helical computed tomography (CT). MATERIALS AND METHODS Neither institutional review board approval nor patient consent was required for this retrospective study. Thirty-eight patients underwent follow-up helical(More)
OBJECTIVE We report our experience with thin-collimation helical CT in a population of patients suspected of having pulmonary embolism. CONCLUSION Thin-collimation helical CT provided technically acceptable examinations for pulmonary embolism in 360 patients (97%). In this population, CT revealed pulmonary embolism in 104 patients (29%), negative findings(More)
PURPOSE To evaluate thin-section computed tomography (CT) in depicting longitudinal changes in the lung parenchyma. MATERIALS AND METHODS One hundred eleven volunteers underwent sequential examination with thin-section CT and pulmonary function tests over a mean period of 5.5 years. According to their smoking habits between initial evaluation (T0) and(More)
The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251(More)
To study the signs of coal worker's pneumoconiosis (CWP) at computed tomography (CT), the authors obtained thoracic CT scans in 170 coal-dust-exposed workers who were concomitantly evaluated with conventional posteroanterior and lateral radiography. The profusion and extent of disease was assessed by means of CT in two groups of miners: group 1 (n = 86),(More)
A total of 109 single or multiple pulmonary arteriovenous malformations (PAVMs) were evaluated with computed tomography (CT) of the chest in 40 patients separated into three groups to study the usefulness of CT (a) in the diagnosis and pretherapeutic management of PAVMs by comparison with selective pulmonary angiography of each lung (group 1: 20 patients),(More)
PURPOSE To determine the clinical utility of three-dimensional (3D) helical computed tomography (CT) in pretherapy evaluation of the angioarchitecture of pulmonary arteriovenous malformations (PAVMs). MATERIALS AND METHODS Thirty-seven PAVMs were prospectively evaluated with both helical CT and pulmonary angiography. Single-threshold shaded-surface(More)
