WebA brain SPECT, or Single Photon Emission Computed Tomography, scan is used to detect altered blood flow in the brain. A SPECT scan is a nuclear medicine exam that uses a radioactive compound to diagnose some diseases of the brain. It is a form of radiology because radiation is used to capture pictures of the human body. Procedural Details WebMethods: A quantitative I-123 single-photon emission computed tomography (SPECT)/CT (5 mCi) was performed in one patient with unilateral AFTN and T3 thyrotoxicosis. The I-123 concentrations measured at 24 h were 12.26 µCi/mL and 0.11 µCi/mL in the AFTN and contralateral ETT, respectively. Thus, the I-131 concentrations and radioactive iodine ...
