PET, also known as positron emission computed tomography, can be localized or systemic imaging. Current examination items mainly include: oncological diseases: differential diagnosis of most benign and malignant tumors, staging and grading of tumors, and evaluation of systemic conditions; and evaluation of the efficacy of various therapeutic means before and after treatment.
PET images reflect the physiological and biochemical distribution of drugs labeled with positron-emitting nuclides in the body, as well as changes over time. By using different drugs, it is possible to measure the activity of glucose metabolism in tissues, the rate of protein synthesis, and the density and distribution of receptors. For this reason, PET is also known as “in vivo biochemical imaging”.
PET has the ability to accurately identify most tumors, including bone, and is useful for early clinical detection of tumors, especially deep-seated tumors, such as tumors in the abdominal cavity, pelvis, lungs, retroperitoneum, and other hidden areas.
PET examination is also helpful in the differential diagnosis of most benign and malignant tumors in human body, determining the staging and grading of tumors, as well as evaluating whether malignant tumors such as lung cancer, breast cancer, intestinal cancer, lymphoma, and so on, have reached a complete remission after radiation and chemotherapy.
Please consult the relevant physicians about the detailed pet examination items and conduct the relevant examinations under the guidance of physicians.
