正电子发射断层扫描 (PET) is a specialized radiology procedure that uses molecular imaging to track and trace both normal and abnormal conditions. PET是最先进的核成像技术, allowing for high-resolution imaging and absolute quantification of biologic mechanisms. PET imaging is also used to follow the progress of patients undergoing treatment. 而PET最常用于神经学领域, 肿瘤学和心脏病学, 目前正在研究在其他领域的应用.

我们的使命

我们的使命是引领发现, teaching and application of PET agents and methods for justly distributed and improved person-centric care.

关于宠物

The Johns Hopkins PET radiotracer center has been in continuous operation since installation of our first cyclotron in 1983. 它是发现新型放射性示踪剂的主要中心之一, implementation of promising new radiotracer discovered elsewhere and for managing patients in our community.

PET is a molecular imaging technique that measures biochemistry noninvasively from preclinical studies in small animal

S对人类. The technique works by detecting the annihilation of positrons that occur within living subjects after administration of a positron-emitting radiotracer that is targeted to a specific receptor, 转运体, 酶或抗原. The annihilation photons are detected as they arrive in coincidence at opposite detectors placed around the patient in the scanner. An image is reconstructed from the position of the detected photons as they leave the body creating an image of biochemical activity occurring at the diseae site and in the whole body. PET scanning has been a clinically valuable technique for both research and patient management since the 1980s. However, it is only been within the last 20 years that the Centers for Medicare & 医疗补助服务(CMS)已经报销了临床PET研究, 使它们在美国广泛使用.

这种高级PET成像研究很少单独进行. 目前, PET is performed in conjunction with computed tomography (CT) that provides anatomic information and the fused molecular and anatomic (CT) images are interpreted together as PET/CT studies. The majority of those studies utilize a positron-emitting form of glucose, 称为氟脱氧葡萄糖(FDG), 检查肿瘤代谢情况. But there are many other such studies that we preform clinically to guide disease diagnosis and monitoring response to therapy.

我们的PET中心团队每年进行超过4,300例手术. Our subspecialty-trained radiologists manage and interpret every PET scan. 这些高级, high-resolution images allow our team and clinical partners access to both the structure and function of organ systems within the body. Our state-of-the-art equipment and technology serve as the backdrop to our unwavering commitment to excellent patient care and attention to detail.

PET扫描常用于帮助诊断 cancer, detect the spread of cancer to other parts of the body, or measure the effectiveness of 癌症治疗. Other uses include diagnosing diseases of the brain and heart, such as 阿尔茨海默病, 帕金森病, 亨廷顿氏舞蹈症, 癫痫, stroke炎症性心脏病或 冠状动脉疾病.

下一代:PET/CT

Recent technical advances have resulted in the combination PET scanners together with X-ray CT in a single camera system. These hybrid systems yield maximum structural and biological information with a single noninvasive imaging study, 结合PET和CT的力量. Our scans help diagnose, treat and evaluate various conditions and diseases
