Abstract

Proper collimator selection is critical to obtaining high-quality, inter-pretable nuclear medicine images. Collimators help eliminate scatter, which leads to poor spatial resolution and blurry images. We present the case of a posttherapy 177 Lu-DOTATATE (Lutathera) patient who was initially imaged with a low-energy, high-resolution collimator routinely used in 99m Tc imaging. On image review, the patient was reimaged with the appropriate medium-energy, high-resolution collimator, which resulted in improved image quality. When reviewing the quality of images, it is important to understand modi fi cations to the imaging that can signi fi cantly improve image quality and interpretation.
明智选择您的准直器:在 177Lu-DOTATATE 治疗后扫描中不恰当地选择准直器
正确选择准直器对于获得高质量、可相互读取的核医学图像至关重要。准直器有助于消除导致空间分辨率低和图像模糊的散射。我们介绍了一例治疗后 177 Lu-DOTATATE (Lutathera) 患者的病例,该患者最初使用 99m Tc 成像中常规使用的低能量、高分辨率准直器成像。在对图像进行复查时,使用适当的中等能量、高分辨率准直器对患者进行了重新成像,从而提高了图像质量。在复查图像质量时,重要的是要了解对成像进行修改能显著提高图像质量和解释能力。
