摘要

摘要：意外动脉内注射放射性核素导致特殊成像模式的事件非常罕见，被描述为 "热臂"、"热手"、"手套现象 "或 "手套样模式"。我们介绍了一例 68Ga-DOTATATE 全身 PET/CT 用于神经内分泌肿瘤重新分期的病例，其中动脉内误注导致了手套现象。与本病例一样，患者可能表现出极少的症状，而 PET 检查结果可能只出现在上肢远端（置于头部上方），因此全身 PET/CT 的视野较长，可能更容易发现这些意外注射。放射医师和技术人员应注意这种可能性，以避免意外误注射。

Glove Phenomenon Detected by Total-Body PET/CT With 68 GA-DOTATATE.

Abstract: Accidental intra-arterial injections of radiotracers are rare events resulting in a specific imaging pattern, described as "hot-forearm," "hot-hand," "glove-phenomenon," or "glove-like pattern." We present a case 68 Ga-DOTATATE total-body PET/CT for restaging of a neuroendocrine tumor, where intra-arterial misinjection resulted in a glove phenomenon. Since patients may present with minimal symptoms, like in this case, and PET findings may only be seen at the distal upper extremity (placed above the head), these accidental injections may be more frequently detected with total-body PET/CT due to the longer field-of-view. Radiologists and technologists should be aware of this possibility to avoid accidental misinjections.
