Longer dwell times do not correlate with pneumothorax and should not influence the decision to obtain more biopsy samples. A shallow pleural puncture angle may increase the pneumothorax rate.

CT commonly helped identify small nodules. Increase in size occurred infrequently and almost exclusively in patients with a known malignancy.

Detection of pulmonary embolism with helical CT may be less accurate than previously reported. Given its high specificity but relatively low sensitivity, helical CT may not have the ideal attributes of a first-line imaging study for the diagnosis of pulmonary embolism.

RESULTS. Smooth septal thickening. bilateral pleural effusions, vascular redistribution,and cardiac enlargement were the most common CT findings in patients with CHF. Enlarged

During acute infection, patients commonly had ground-glass opacities but lacked pleural effusions and lymph node enlargement. There can be chronic sequelae after infection.
