Abstract

We assess the usefulness of F-18-fluoro-deoxyglucose (FDG) positron emission tomography (PET) in the evaluation of gastrointestinal metastases. Four cases (five lesions) in which metastases from three lung cancers and one malignant fibrous histiocytoma (MFH) of the femur were found in the gastrointestinal tract were reviewed (men/women 3 : 1, age 63-78 years, mean 72 years). The five lesions were duodenal, jejunal metastasis, and two stomach metastases from lung carcinoma, and rectal metastasis from MFH of the femur. FDG-PET was unable to detect small masses, but it was able to detect unforeseen lesions such as gastrointestinal metastases because FDG-PET is a whole-body scan in a single-operation examination. FDG-PET imaging provided valuable information for the diagnosis of gastrointestinal metastasis.

摘要

我们评估了F-18-氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）在评估胃肠道转移瘤方面的实用性。回顾了4例（5个病灶）病例，这些病例中在胃肠道发现了来自3例肺癌和1例股骨恶性纤维组织细胞瘤（MFH）的转移瘤（男性/女性为3:1，年龄63 - 78岁，平均72岁）。这5个病灶分别为十二指肠、空肠转移瘤，2个来自肺癌的胃转移瘤，以及1个来自股骨MFH的直肠转移瘤。FDG-PET无法检测到小肿块，但由于FDG-PET是一种单次检查的全身扫描，所以能够检测到诸如胃肠道转移瘤等意外病灶。FDG-PET成像为胃肠道转移瘤的诊断提供了有价值的信息。
