Spect ct radiation dose
WebMethods: SPECT and CT image acquisition parameters such as administered activity (AA), CT dose index (CTDI vol ), and dose-length product for 415 patients who had undergone SPECT MPI using CT attenuation correction were reviewed. Effective dose (ED) for the SPECT part, the CT part and the total ED for the procedure were calculated.
