MATERIALS AND METHODS The chest(More)
PURPOSE To test the hypothesis that absence of statistically significant lung nodule enhancement (< or =15 HU) at computed tomography (CT) is strongly predictive of benignity. MATERIALS AND METHODS Five hundred fifty lung nodules were studied. Of these, 356 met all entrance criteria and had a diagnosis. On nonenhanced, thin-section CT scans, the nodules(More)
BACKGROUND Social anxiety disorder (SAD) (also known as "social phobia") is frequently comorbid with major depression, and in such cases, almost always precedes it.

MATERIALS AND METHODS CT scans of 12 patients with hemorrhagic pulmonary nodules and of a control group of 10 patients with nonhemorrhagic pulmonary nodules were randomized and reviewed by two chest(More)
