肺胸膜病変の診断における三次元volume rendering CTの有用性

摘要

Three-Dimensional Volume Rendering CT images focused on pleural plane of thoracic diseases were reviewed. Visceral pleural lesions caused by interstitial pneumonitis, etc were clearly displayed. In bullous emphysema, inflated pleural plane were observed. The depressions of pleural surface were also seen in patients with chest wall mass or parietal pleural plaque. Interlobar fissure line were more clearly observed compared with conventional axial CT images. We can evaluate the severity and distribution of the interlobular septal thickening in patients of lymphop-roripherative disease or congestive heart failure. These results suggest that volume rendering 3DCT using optimized display can serve as the useful method in analysis of the pleural lung lesions.
