    What does hypercaptation mean?

    What does hypercaptation mean?

    Hypercaptant (uptake of the nodule greater than the surrounding thyroid tissue) Isocaptive or "lukewarm" (nodular uptake equal to the surrounding thyroid tissue) Hypocaptant (less nodular uptake than the surrounding thyroid tissue).

    What does SUV mean in PET?

    A retrospective study suggests that the maximum standardized uptake value (SUVmax) in 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) of primary tumors is associated with disease risk. ...

    What does choline PET show?

    What does secondary injury mean?

    What does hot or cold lump mean?

    Nodules in which iodine uptake is greater than that of normal tissue are called warm nodules; those, on the other hand, in which uptake is lower or absent are defined as cold nodules.

    When is PET negative?

    A negative PET investigation is able to correctly identify which patients to refer to the oncologist surgeon and which not, avoiding them this extremely invasive procedure.

    When is PET prescribed?

    Primarily, positron emission tomography used to confirm a tumor diagnosis or evaluate the efficacy of cancer therapy. PET is particularly useful for understanding: If and where a tumor has developed; If the cancer has spread or spread to sites other than those already known.

    How much does a tumor grow in a year?

    Malignant lesions typically have a doubling time in size of between one month and one year; therefore, a lump that doubles in size in less than a month, or that has remained stable in size for more than 1-2 years, is more likely benign.
