Reconstructed urinary bladder following radical cystectomy for bladder cancer. Multidetector CT evaluation of normal findings and complications.
The aim of this paper is to report the normal and pathological multidetector computed tomography (MDCT) findings in the morphofunctional evaluation of the orthotopic ileal reservoir in patients treated with radical cystectomy for transitional cell carcinoma. ⋯ MDCT of the contrast-filled neobladder is useful for the morphological and, in part, functional evaluation of the neobladder during postoperative follow-up and helps detect surgical complications. Radiation protection concerns do not, however, support the routine use of the method, even if the MDCT data are in part correlated to the urodynamic data and may in many cases provide a morphological explanation to the presence of functional alterations.

In vivo measurement of the apparent diffusion coefficient in normal and malignant prostatic tissue using thin-slice echo-planar imaging.
Diffusion is a physical process based on the random movement of water molecules, known as Brownian movement. Diffusion-weighted imaging (DWI) is a magnetic resonance imaging (MRI) technique that provides information on such biophysical properties of tissues as density, cell organisation and microstructure, which influence the diffusion of water molecules. The aim of this study was to evaluate the ability of MRI to obtain information on the diffusion of water molecules in normal and malignant prostate tissues. ⋯ Our preliminary results indicate that DWI is useful for characterising tissue in the different regions of the prostate gland and in distinguishing normal from cancerous tissues, given its ability to detect early changes in the structural organisation of prostate tissue.

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.

Lung sonography, generally not thought to be diagnostic, is currently being reconsidered and is developing into an interesting clinical possibility. The principal sonographic signs of lung disease are described in light of our personal experience and the current literature.

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.
