To define the role of computed tomography (CT) in children aged 2 years and younger with head trauma, suspected abuse, and normal neurologic findings. ⋯ No child with normal neurologic findings had a clinically important abnormality depicted at CT. CT scans did not alter clinical management, clinical outcome, or legal outcome. Thus, routine CT of all patients with skull fractures in this population may be unnecessary.

Multicenter Study
Ventilator-associated pneumonia in patients with adult respiratory distress syndrome: CT evaluation.
To determine the diagnostic accuracy of computed tomography (CT) for pneumonia in patients with adult respiratory distress syndrome (ARDS). ⋯ CT has fair diagnostic accuracy for ventilator-associated pneumonia in patients with ARDS owing primarily to identification of patients without pneumonia. No single CT sign was significantly different for pneumonia, but dependent atelectasis was more common in patients with early ARDS without pneumonia.

Comparative Study
Pulmonary embolism: diagnosis with spiral CT and ventilation-perfusion scanning--correlation with pulmonary angiographic results or clinical outcome.
To compare the accuracy of spiral computed tomography (CT) with that of ventilation-perfusion (V-P) scintigraphy in the diagnosis of pulmonary embolism (PE). ⋯ Spiral CT has greater accuracy and specificity than V-P scanning in patients with an unresolved diagnosis and may be useful as the primary screening technique for PE.

To evaluate in a pilot study the feasibility and efficacy of endovascular brachytherapy for prophylaxis of restenosis after femoropopliteal percutaneous transluminal angioplasty (PTA) without stent implantation in a group of patients with a high risk of restenosis. ⋯ Considering the negative selection of patients with a high risk of restenosis, the results of our pilot study are promising concerning the possibility of reduction of restenosis by means of endovascular brachytherapy after long-segment femoropopliteal PTA without stent implantation. The value of this approach should now be determined definitively in randomized trials.
