Abstract

MR imaging and PET using 2-Deoxy-2-[F]fluoroglucose (FDG) are both useful in the evaluation of gynecologic malignancies. MR imaging is superior for local staging of disease whereas fludeoxyglucose FDG PET is superior for detecting distant metastases. Integrated PET/MR imaging scanners have great promise for gynecologic malignancies by combining the advantages of each modality into a single scan. This article reviews the technology behind PET/MR imaging acquisitions and technical challenges relevant to imaging the pelvis. A dedicated PET/MR imaging protocol; the roles of PET and MR imaging in cervical, endometrial, and ovarian cancers; and future directions for PET/MR imaging are discussed.

摘要

使用2-脱氧-2-[F]氟葡萄糖（FDG）的磁共振成像（MR成像）和正电子发射断层显像（PET）在妇科恶性肿瘤的评估中均很有用。MR成像在疾病局部于疾病的局部分期更具优势，而氟脱氧葡萄糖FDG PET在检测远处转移方面更具优势。集成式PET/MR成像扫描仪通过将每种模态的优势整合到一次扫描中，在妇科恶性肿瘤方面具有巨大潜力。本文回顾了PET/MR成像采集背后的技术以及与盆腔成像相关的技术挑战。讨论了专门的PET/MR成像方案、PET和MR成像在宫颈癌、子宫内膜癌和卵巢癌中的作用，以及PET/MR成像的未来发展方向。
