The Application of PET and PET/CT to Breast Cancer

摘要

Positron emission tomography (PET) is a radiotracer imaging method that uses positron-emitting radiopharmaceuticals to generate images of regional biochemistry. Relatively high spatial resolution, the ability to measure quantitative regional tracer concentration, and, importantly, the range of biologically interesting radiopharmaceuticals that can be generated with positron emitters such as fluorine 18 (~(18)F) and carbon 11 are important features of PET. More recently, the combination of PET and computed tomography (CT) into PET/CT devices provides simultaneous functional and anatomic imaging that is highly advantageous in tumor imaging (1).
