The purpose of this study was to show the effectiveness of ultrasound (US) in the evaluation of pneumothorax by comparison with X-rays and computed tomography (CT). ⋯ Chest US was found to be a valuable diagnostic tool in pneumothorax diagnosis, with diagnostic effectiveness well beyond X-rays and similar to CT.

64 slice cardiovascular CT in the emergency department: concepts and first experiences.
The purpose of this study was to evaluate contrast-enhanced electrocardiogram (ECG)-gated 64-slice computed tomography (CT) angiography of the thorax as a triage tool in patients with acute equivocal chest pain. ⋯ Our initial experience shows that ECG-gated 64- slice CT angiography of the entire thorax is technically feasible and enables rapid triage of patients to determine underlying cardiac and noncardiac reasons for chest pain. This test may thus help to significantly reduce costs and length of hospitalisation. Prospective studies involving larger groups of patients are required to confirm these findings.

Role of magnetic resonance in characterising extrahepatic cholangiocarcinomas.
The purpose of this study was to evaluate the accuracy of magnetic resonance (MR) in correctly locating and characterising biliary strictures in patients affected by extrahepatic cholangiocarcinoma, identify findings suggestive of the disease, identify lesions with similar MR features and possible criteria for differential diagnosis and establish prospective MR accuracy in diagnosis of malignant obstruction of extrahepatic bile ducts. ⋯ MR almost always identified the cause of stenosis and suggested its neoplastic nature if it exhibited a mass-like appearance (extraductal or growing into the choledochus). On the other hand, lesions with parietal thickening, particularly if smaller than 1 cm, require endoscopic cytology or histology because of the high risk of unnecessary procedures for benign lesions.

Tracheobronchial aspiration of foreign bodies: current indications for emergency plain chest radiography.
The purpose of this study was to determine the role of plain chest radiography in the evaluation of patients with suspected foreign-body aspiration. ⋯ Plain chest radiography remains the initial imaging modality for patients with clinically suspected tracheobronchial aspiration of a foreign body. Nevertheless, in the case of negative chest radiography and a clinical suspicion of foreign-body aspiration, MSCT-possibly integrated with virtual bronchoscopy-should be considered in order to avoid unnecessary bronchoscopy.
