Quantitative Scintigraphy Evaluated the Relationship between 131I Therapy and Salivary Glands Function in DTC Patients: A Retrospective Analysis
Figure 2
Physiological uptake and excretion of 99mTc-pertechnetate in parotid and submandibular salivary glands detected by dynamic salivary gland scintigraphy. (a) A clear depiction of the ROIs and ROIs of the salivary and mandibular glands was obtained from all frames. (b) The parotid gland was in the bilateral temporal-orbital region, and the mandibular gland was in the bilateral supraclavicular region to draw similar background areas, and the background ROIs count was recorded. (c-d) Time-activity curve of each salivary gland. The ordinate of a1-a4 corresponds to the maximum minute count of each salivary gland. The ordinate of b1- b4 corresponds to the count of each salivary gland at the minimum uptake minute after vitamin C.
