How to Appropriately Calculate Effective Dose for CT Using Either Size-Specific Dose Estimates or Dose-Length Product.
OBJECTIVE The purpose of this study is to show how to calculate effective dose in CT using size-specific dose estimates and to correct the current method using dose-length product (DLP). MATERIALS AND METHODS Data were analyzed from 352 chest and 241 abdominopelvic CT images. Size-specific dose estimate was used as a surrogate for organ dose in the chest and abdominopelvic regions. Organ dose...
متن کاملCardiac-Specific Conversion Factors to Estimate Radiation Effective Dose From Dose-Length Product in Computed Tomography.
OBJECTIVES This study sought to determine updated conversion factors (k-factors) that would enable accurate estimation of radiation effective dose (ED) for coronary computed tomography angiography (CTA) and calcium scoring performed on 12 contemporary scanner models and current clinical cardiac protocols and to compare these methods to the standard chest k-factor of 0.014 mSv·mGy-1cm-1. BACKG...
متن کاملEstimation of fetal absorbed dose from low-dose attenuation-correction CT in PET / CT imaging by using the Body Builder Phantom
One of the methods of studying the physiology and metabolism of important tissues such as the heart, brain and cancer tumors is the use of PET/CT System. A small number of patients are pregnant women who undergo a PET/CT scan due to lack of knowledge about pregnancy or due to dire clinical need. The final dose received by the fetus is based on three factors: the absorbed dose of the fetal tissu...
متن کاملAssessment of Patient Dose from CT Examinations in Khorasan, Iran
Introduction Computed Tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. Ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. Yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. Materials and Methods Two refe...
متن کاملDesigning CT scanning rooms and estimating patient and personnel absorbed dose using code (MCNPX 2.6)
One of the most widely used diagnostic devices in medical imaging is computed tomography scanning with the use of X-ray ionization. After years of using this tool in the diagnosis and treatment, external doses of these beams can pose a risk of secondary cancer, which is significant in terms of radiation safety and protection. In this paper, using the Monte Carlo code MCNPX2.6 performed over thr...
