The extent and volume of the lesions decreased at follow-up CT. The opacity of the lesions was highest at 1 week then it decreased gradually to an area of ground-glass opacity. RESULTS: Diffuse ground-glass opacity was noted on all immediately obtained scans. Findings at CT were correlated with those in the histopathologic specimens. The CT number in consolidation areas also was measured. Scans were assessed for opacity, distribution, location at the lobular level, extent, and volume of the lesions. Thin-section CT scans were obtained within 1 hour and at 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after oil administration.
MATERIALS AND METHODS: Shark liver oil was administered to 12 sites in seven pigs.
PURPOSE: To evaluate sequential changes in thin-section computed tomographic (CT) findings after inducement of lipoid pneumonia and provide the histopathologic bases of these findings.
