Personalized Treatment in Thyroid Disorders

"Study Device; The CoTI has 3 components;~* A collar unit: a gamma detector wrapped around a body part-neck in this case and contains a scintillating crystal and a silicon photomultiplier. The photon pulse signal is then converted to digital signals (measuring the counts per second). Usually two detectors are placed in specified positions.~* A cable that connects the collar unit to the Control Unit~* A control unit that collects the signals and transmits it wirelessly to a hand-held computer tablet.~Two types of collar devices will be used: the lower activity and the medium activity~1. Lower activity collar for patients with Graves' disease as well as diagnostic I-123 scan in thyroid cancer patients. These patients typically receive 0.2-1.2 m Ci of I-123/I-131.~2. Medium activity collar for Patients with thyroid cancer after 131-I ablation, for which patients typically receive 30-100 mci of I-131."
