Findings in 30 consecutive patients with pneumothorax were prospectively analyzed. All patients underwent supine anteroposterior (AP) and erect posteroanterior (PA) chest radiography. ⋯ Average interpleural distances on supine AP and erect PA radiographs were analyzed by means of correlation and linear regression analysis. The authors developed a formula that can be used to estimate the size of a pneumothorax on a supine AP chest radiograph.

Endoluminal virtual computed tomographic (CT) cholangiopancreatoscopic views of the pancreatic and common bile ducts were generated in 16 patients by using helical CT data sets and endoscopic three-dimensional reconstruction images. In all patients with ductal dilatation, virtual images were obtained and findings correlated with those at helical CT and endoscopic retrograde cholangiopancreatography. Virtual CT cholangiopancreatoscopy is a feasible technique, and initial experience shows promising results.

To determine the clinical usefulness of thoracic computed tomography (CT) in patients in a general intensive care unit (ICU). ⋯ CT of the thorax is clinically useful in selected situation in patients in ICUs.

To evaluate the perfusion magnetic resonance (MR) imaging characteristics of cerebral toxoplasmosis and lymphoma in patients with acquired immunodeficiency syndrome (AIDS). ⋯ Reduced rCBV i toxoplasmosis lesions is probably due to a lack of vasculature within the abscess; increased rCBV in lymphomas is probably due to hypervascularity in foci of active tumor growth; and decreased rCBV in the edema is probably due to vasoconstriction associated with increased interstitial pressure. Perfusion MR imaging is a rapid, noninvasive tool that may allow differentiation between cerebral lymphoma and toxoplasmosis in patients with AIDS.
