This advanced medical imaging technique combines positron emission tomography (PET) with computed tomography (CT) and incorporates time-of-flight technology. It measures the time difference between the detection of two gamma rays produced when a positron emitted by a radiotracer interacts with an electron in the body. This precise timing information allows for more accurate localization of the radiotracer, resulting in sharper images with improved contrast and reduced noise. For instance, it can help pinpoint the location of small tumors or metastases with greater precision.
Enhanced image quality leads to several significant advantages. It enables earlier and more accurate disease detection, particularly in oncology, cardiology, and neurology. The improved signal-to-noise ratio allows for reduced scan times and lower doses of radiotracers, minimizing patient exposure to radiation. This technological advancement builds upon traditional PET/CT imaging by incorporating timing information, representing a significant leap forward in diagnostic capabilities. This evolution has had a profound impact on disease management and treatment planning.
