Abstract

This paper describes a method for the enhancement of curvilinear structures such as vessels and bronchi in three-dimensional (3-D) medical images. A 3-D line enhancement filter is developed with the aim of discriminating line structures from other structures and recovering line structures of various widths. The 3-D line filter is based on a combination of the eigenvalues of the 3-D Hessian matrix. Multi-scale integration is formulated by taking the maximum among single-scale filter responses, and its characteristics are examined to derive criteria for the selection of parameters in the formulation. The resultant multi-scale line-filtered images provide significantly improved segmentation and visualization of curvilinear structures. The usefulness of the method is demonstrated by the segmentation and visualization of brain vessels from magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), bronchi from a chest CT, and liver vessels (portal veins) from an abdominal CT.

Organizing pneumonia: typical and atypical HRCT patterns.

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 modality of response of the lung to various forms of injury. Typical computed tomography (CT) pattern has been widely described and consists of peripheral parenchymal consolidations with air bronchogram with or without surrounding ground-glass-like opacities. The purpose of this article is to describe the less frequent imaging pattern of this disease represented by single or multiple focal lesions (nodules or masses that place diagnostic problems with malignancy), bronchocentric pattern (parenchymal consolidations with peribronchovascular distribution), atoll sign (central area of ground-glass-like density and peripheral area of consolidation), nodular lesions (poorly defined micronodular pattern), linear and band-like opacities (subpleural linear opacities that can have disposition parallel or perpendicular in relation to the pleura), perilobular pattern (thickening of the interlobular septa with reticular pattern) and progressive fibrotic pattern (irregular thickening of the interlobular septa with associated ground-glass-like appearance and consolidations).

Successful use of recombinant factor VII in massive hemoptysis due to community-acquired pneumonia.

Recombinant activated factor VII (rFVIIa) is a powerful hemostatic agent developed for use in hemophilia. It has been used increasingly in life-threatening hemorrhage in a variety of other settings in which conventional medical or surgical therapy is unsuccessful. This report describes the successful use of rFVIIa for pulmonary hemorrhage due to a focal bleeding source in a regional hospital where bronchial artery embolization or surgery were not available. rFVIIa may be a useful temporizing measure in the unstable patient with pulmonary hemorrhage without coagulopathic bleeding when conventional treatment is not immediately available.

Imaging evolution of airway disorders in children.

This article discusses and illustrates the insights gained from CT imaging of the lungs in infants and young children who do not have respiratory motion and at end-inspiratory and resting end-expiratory lung volumes using noninvasive controlled ventilation CT technique. The potential role of noninvasive controlled ventilation CT in developing quantitative measures of airway disease is highlighted and clinical examples demonstrating the use of the technique are shown.
