自2013年以来,在日本使用常规全身PET进行乳腺正电子发射断层扫描(PET)已获得保险。连同全身PET,乳腺癌的准确检查和转移性疾病的诊断是可能的,并有望为其治疗计划做出重大贡献。为了更安全,更平滑,更合适的检查,日本核医学会于2013年发布了第一版高分辨率乳腺PET实践指南.随后,已经开发了新类型的乳腺PET,并阐明了其临床用途。因此,乳腺PET指南于2019年修订.本文向读者介绍了第二版中的新内容。根据探测器的放置,此版本支持两种不同类型的乳房PET:相反类型(正电子发射乳房X线照相术;PEM)和环形类型(专用乳房PET;dbPET),提供这些扫描仪和适当的成像方法的概述,它们的临床应用,和未来的前景。第一版的“专用乳房PET”名称广泛用于指环形型乳房PET。在这个版本中,“乳房PET”已被定义为一个术语,指的是相反和环形装置。最新的乳房PET实践指南将有助于为基于证据的乳房成像提供有用的信息。
Breast positron emission tomography (PET) has had insurance coverage when performed with conventional whole-body PET in Japan since 2013. Together with whole-body PET, accurate examination of breast cancer and diagnosis of metastatic disease are possible, and are expected to contribute significantly to its treatment planning. To facilitate a safer, smoother, and more appropriate examination, the Japanese Society of Nuclear Medicine published the first edition of practice guidelines for high-resolution breast PET in 2013. Subsequently, new types of breast PET have been developed and their clinical usefulness clarified. Therefore, the guidelines for breast PET were revised in 2019. This article updates readers as to what is new in the second edition. This edition supports two different types of breast PET depending on the placement of the detector: the opposite-type (positron emission mammography; PEM) and the ring-shaped type (dedicated breast PET; dbPET), providing an overview of these scanners and appropriate imaging methods, their clinical applications, and future prospects. The name \"dedicated breast PET\" from the first edition is widely used to refer to ring-shaped type breast PET. In this edition, \"breast PET\" has been defined as a term that refers to both opposite- and ring-shaped devices. Up-to-date breast PET practice guidelines would help provide useful information for evidence-based breast imaging.
