AN OVERVIEW - RADIATION DOSE TO PATIENTS DURING SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY (SPECT)

The objective is to evaluate the radiation dosage received by the patient during regular clinical single-photon emission computed tomography-computed tomography (SPECT-CT) and quantify the increase in comparison to SPECT alone. Incorporating CT into nuclear medicine imaging, specifically in the form of SPECT-CT, results in an elevated radiation dose for the patient. In fact, the effective dose from CT often surpasses the effective dose from RP in numerous cases. Therefore, it is necessary to effectively employ and optimize the protocols of SPECT-CT in order to maximize the advantages for patients. Implementing a dose-tracking software provided a simple method for optimization. In addition, we can readily compute the primary dosimetric parameters and monitor their patterns on a daily basis to promptly implement any required corrective measures in real-time.
