The calculated mean and SD of effective doses from head, chest and abdomen CT scan were 1.5+0.9, 7.5+3.7, and 11.5+3.8 millisieverts (mSv), respectively.Ĭonclusion: Radiation dose from CT scans of the brain, chest, or abdomen were varied depending on an individual patient and the exposure technique. Radiation doses varied significantly between the different types of CT studies. Results: These three study types were approximately 70% of the total CT examinations. The effective dose of each patient was calculated. The CTDI volume (CTDI vol), dose length product (DLP), kV and mAs were recorded. A retrospective cross-sectional study of radiation dose of 1,200 patients were collected between February to April 2014. Method: This study was approved by the Human EthicsCommittee of Khon Kaen University (HE571239). The purpose of this study was to assess the radiation dose in the three most common examinations of diagnostic CT studies which were brain, chest and abdomen performed at Srinakarind hospital. Background and Objective: Computed tomography ( CT) is an imaging procedure that uses a special x-ray equipment to create detailed pictures, or scans, of areas inside the body. Although CT is essentially useful in diagnosis, potential cancer risks exist from associated with ionizing radiation.
