Non-thrombotic PE does not represent a distinct clinical syndrome. It may be due to a variety of embolic materials and result in a wide spectrum of clinical presentations, making the diagnosis difficult. With the exception of severe air and fat embolism, the haemodynamic consequences of non-thrombotic emboli are usually mild. Treatment is mostly supportive(More)
BACKGROUND Lung cancer has the highest mortality-rate per cancer, with an overall 5-year survival <15%. Several non-randomized studies pointed out the high sensitivity of low dose computed tomography (LDCT) to detect early stage lung cancer. In France, Depiscan, a pilot RCT of LDCT versus chest X-ray (CXR), started on October 2002 to determine the(More)
The aim of the present study was to assess the prevalence and characteristics of airways involvement in rheumatoid arthritis (RA) patients in the absence of interstitial lung disease. We prospectively evaluated, with high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs), 50 patients with RA (nine males and 41 females; mean age: 57.8(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)
BACKGROUND Diagnosis of pulmonary embolism (PE) is difficult in patients with chronic obstructive pulmonary disease (COPD) and exacerbation. OBJECTIVE To evaluate PE in patients with COPD and exacerbation of unknown origin and explore factors associated with PE. DESIGN Prospective cohort study. SETTING University-affiliated hospital in France. (More)
OBJECTIVE Our objective was to assess high-resolution CT findings of respiratory bronchiolitis, respiratory bronchiolitis-associated interstitial lung disease, and desquamative interstitial pneumonia and to determine whether these three entities could be reliably differentiated by radiologic criteria. MATERIALS AND METHODS CT scans (1- to 3-mm(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)
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)
