Analysis of Pulmonary Metastases by Three-dimensional CT Images
Yasuji Oshiro11Department of Radiology, School of Medicine, University of the Ryukyus, Japan.
Newly developed multidetector-row CT can acquire whole lung data during a single breath hold. With multi-slice data, high resolution 3D reconstruction images can be easily obtained in daily practice. Three-dimensional reconstruction images such as multiplanar reconstruction (MPR) and maximum intensity projection (MIP) are useful to evaluate the association between pulmonary metastases and surrounding pulmonary structures. It is well known that typical radiologic findings of a pulmonary metastasis are of a round nodule or mass with a smooth margin. However, metastases with atypical radiologic features are often encountered, and are often difficult to distinguish from non-malignant pulmonary diseases or primary lung cancer. Detailed knowledge of the atypical radiologic features of pulmonary metastases is essential for correct diagnosis.
