Positron Emission Tomography (PET) is a non-invasive imaging diagnostic tool that allows the study of specific biochemical processes using labeled molecules that closely mimic endogenous molecules. The two radiopharmaceuticals used in our facility are 13N-Ammonia and 18F-2-deoxy-2 fluor D-glucose (18F-FDG). 18F-FDG is the most common radiopharmaceutical used both at our Unit as well as worldwide, as it allows the study of tumor activity, the heart's metabolic activity, distinguish viable from non-viable myocardium and assess cerebral metabolism, among others.
Describe the experience in the use of PET scan in our country in the fields of oncology, cardiology and neuropsychiatry.
We performed an observational, retrospective, cross-sectional, and descriptive study.
We analyzed a total of 1,154 studies performed at the UNAM-PET-Cyclotron Unit belonging to the Faculty of Medicine at the National Autonomous University of Mexico (UNAM). From the studies, 72.1% (832) corresponded to oncology, whereas 18.5% (213) and 9.4% (109) belonged to cardiology and neuropsychiatry, respectively.
The studies performed at the UNAM-PET-Cyclotron Unit places it as the site with the largest PET experience in our country.
正电子发射断层扫描（PET）是一种非侵入性成像诊断工具，它可以使用与内源性分子密切相似的标记分子来研究特定的生化过程。我们机构使用的两种放射性药物是13N-氨和18F-2-脱氧-2-氟-D-葡萄糖（18F-FDG）。18F-FDG是我们科室以及全球范围内最常用的放射性药物，因为它可以用于研究肿瘤活性、心脏代谢活性、区分存活心肌与无存活心肌以及评估脑代谢等。
描述PET扫描在我国肿瘤学、心脏病学和神经精神病学领域的使用经验。
我们进行了一项观察性、回顾性、横断面和描述性研究。
我们分析了墨西哥国立自治大学（UNAM）医学院所属的UNAM-PET-回旋加速器科室进行的总共1154项研究。在这些研究中，72.1%（832项）属于肿瘤学，而18.5%（213项）和9.4%（109项）分别属于心脏病学和神经精神病学。
在UNAM-PET-回旋加速器科室进行的研究使其成为我国PET经验最丰富的场所。
