Molecular breast imaging (MBI) is a nuclear medicine study performed with dedicated gamma camera systems optimized to image the uptake of Tc-99m sestamibi in the breast. MBI provides a relatively low-cost and simple functional breast imaging method that can identify breast cancers obscured by dense fibroglandular tissue on mammography. Recent studies have also found that background levels of uptake in benign dense tissue may provide breast cancer risk information. This article discusses the latest updates in MBI technology, recent evidence supporting its clinical use, and work in progress that may aid in wider adoption of MBI.
分子乳腺成像（MBI）是一种核医学研究，使用专门的伽马相机系统进行，该系统经过优化，可对 Tc-99m sestamibi 在乳房中的摄取情况进行成像。MBI 提供了一种相对低成本且简单的功能性乳房成像方法，可以识别在乳房 X 线摄影中被致密纤维腺体组织遮挡的乳腺癌。最近的研究还发现，良性致密组织中的摄取背景水平可能提供乳腺癌风险信息。本文讨论了 MBI 技术的最新更新、支持其临床应用的最新证据以及正在进行的工作，这些工作可能有助于更广泛地采用 MBI。
