Abstract:Background:
An accurate measurement of the target volume is of primary importance in theragnostics of hyperthyroidism
Objective:
Our purpose was to evaluate the accuracy of a threshold–based isocontour extraction procedure for thyroid tissue volumetry from SPECT-CT.
Methods:
Cylindrical vials with a fixed volume of 99mTcO4 at different activities were inserted into a neck phantom in two different thickness settings. Images were acquired by orienting the phantom in different positions, i.e., 40 planar imag… Show more
