To assess the type, severity, and regional lung distribution of cystic fibrosis (CF) lesions as shown using high-resolution CT (HRCT), comparing these findings with chest radiographs and pulmonary function tests (PFTs), we obtained HRCTs in 36 patients with CF (mean age 13), who were clinically stable. We assessed four lung regions (upper and lower, right(More)
Forty-three CT examinations of the thorax of patients referred for pleural effusion were reviewed. Both normal and thin irregularly thickened pleurae were associated with either neoplastic or non neoplastic disease. In these cases surgery, fine needle biopsy or pleuroscopy may be recommended, their performance being facilitated by the knowledge of the CT(More)
Common features of correct positions, malpositions and complications of central venous catheters are reported. A knowledge of anatomy, high-quality films and appropriate radiological techniques are necessary for the detection of false positions. A few guidelines for diagnosis are suggested.
Organizing pneumonia (OP) is a clinical–pathological entity that, if idiopathic, makes part of the idiopathic interstitial pneumonias classification of the American Thoracic Society/European Respiratory Society (ATS/ERS) of 2002 (50% of the cases, called cryptogenic organizing pneumonia, or COP). In the remaining 50% it is secondary, representing one(More)
A prospective multicentre pilot study was undertaken in 20 Italian hospitals to assess the influence of a routine pre-operative chest radiograph on anaesthetic management and to characterise which patients might benefit from it. A total of 6111 patients undergoing elective surgery and submitted for routine pre-operative chest radiograph were enrolled.(More)
We report the case of a patient that had undergone a left pneumonectomy during which a double-lumen tube was used and an undetected right bronchial laceration occurred. After diagnosis the patient underwent a second operation to repair the tear. The role of high-frequency percussive ventilation in enabling adequate gas exchange during the bronchial repair(More)
Chest roentgenology in the intensive care unit is a real challenge for the general radiologist. Beyond the basic disease, the critically ill is at risk for developing specific cardiopulmonary disorders, all presenting as chest opacities, their diagnosis often being impossible if based only on the radiological aspect. To make things harder, their appearance(More)
PURPOSE The aim of this paper is to present atypical or unusual appearances of pulmonary sarcoidosis, assessed at HRCT, and to suggest some elements for the differential diagnosis. MATERIALS AND METHODS The HRCT scans of 31 patients were retrospectively reviewed. The final diagnosis of sarcoidosis was established on the basis of clinical and laboratory(More)
Malpositions and complications following central venous catheterization largely depend on the site of venous approach. Malpositions are very common after subclavian vein catheterization, and even more common after left jugular vein catheterization. On the contrary, their incidence after right jugular puncture is very low. Among complications, pneumothorax(More)
