Purpose: To compare the accuracy and complication rate of two different CT-guided transthoracic needle biopsy techniques: fine needle aspiration and an automated biopsy device. Methods: Two consecutive series of respectively 125 (group A) and 98 (group B) biopsies performed using 20–22 gauge coaxial fine needle aspiration (group A) and an automated 19.5(More)
OBJECTIVE This study investigates factors influencing the risk of pneumothorax and chest tube placement in patients undergoing CT-guided transthoracic lung biopsy for pulmonary lesions using a coaxial technique. SUBJECTS AND METHODS The study included 307 patients with pulmonary lesions biopsied under CT guidance. Patient-related parameters considered(More)
BACKGROUND Idiopathic pulmonary fibrosis is a chronic progressive disorder with a poor prognosis. METHODS We conducted a double-blind, randomized, placebo-controlled multicenter study that assessed the effectiveness over one year of a high oral dose of acetylcysteine (600 mg three times daily) added to standard therapy with prednisone plus azathioprine.(More)
BACKGROUND We designed a prospective multicentre outcome study to evaluate a diagnostic strategy based on clinical probability, spiral CT, and venous compression ultrasonography of the legs in patients with suspected pulmonary embolism (PE). The main aim was to assess the safety of withholding anticoagulant treatment in patients with low or intermediate(More)
OBJECTIVE We compared helical CT angiography and ventilation-perfusion radionuclide lung scanning as initial tests in the diagnosis of acute pulmonary embolism. SUBJECTS AND METHODS Two hundred sixteen consecutive patients who were clinically suspected of having acute pulmonary embolism underwent helical CT angiography, ventilation-perfusion radionuclide(More)
BACKGROUND & AIMS Non-invasive assessment of liver fibrosis by elastography is a rapidly developing field with frequent technological innovations. The aim of this study was to assess the diagnostic performances of Supersonic Shear Imaging (SSI) for the diagnosis of liver fibrosis in chronic liver disease. METHODS A total of 349 consecutive patients with(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 purpose of this study was to evaluate the performance and complication rate of CT-guided percutaneous lung biopsy of pulmonary lesions using a coaxial automated biopsy device and to determine factors influencing the false negative rate for the diagnosis of malignancy. A prospective study of 605 consecutive biopsies performed in 595 patients was(More)
The epidemiology of methicillin-susceptible Staphylococcus aureus (MSSA) in Africa is poorly documented. From January 2007 to March 2008, 555 S. aureus isolates were collected from five African towns in Cameroon, Madagascar, Morocco, Niger, and Senegal; among these, 456 unique isolates were susceptible to methicillin. Approximately 50% of the MSSA isolates(More)
Quantitative coronary angiography (QCA) is routinely performed before valve surgery for severe acquired valvular disease. This technique is relatively invasive, especially in a population with an average risk for significant coronary stenosis. Multidetector computed tomography (MDCT) coronary angiography allows the noninvasive evaluation of the coronary(More)
