Thyroid gland. Gamma scan (scintigram) of a healthy human thyroid gland. The thyroid gland is a main endocrine gland situated at the base of the neck,and is divided into two joined lobes (as seen). A radioactive tracer substance shows areas of activity within the gland: green (low activity); red (high). The thyroid produces and stores hormones which control the basal metabolic rate of the body,influence growth and maturation,and regulate blood calcium levels. Gamma scanning involves introducing a radioactive tracer into the bloodstream,which is taken up by certain organs and detected as gamma rays by a gamma camera | |
