What is Dosimetric study of pediatric PET/CT scan using different phantoms about?

PET/CT tests are becoming increasingly important imaging tools in the noninvasive evaluation and children monitoring with known or suspected malignant diseases. This equipment allows the functional images overlapping obtained from the radiopharmaceuticals administration and anatomical images generated by X-ray beam attenuation. Although the immediate benefit to the individual patient can be substantial, the relatively high radiation doses associated with PET/CT compared with conventional exams have raised health care. This is especially concerning for children, who are more sensitive to radiation-induced carcinogenesis and have many remaining years to develop cancer. The aim of this study is evaluating and compare the doses generated by the CT scan and incorporated by the radionuclide 18 F-FDG administration for 2 and 10-years old phantoms. To evaluate the CT dose, radiochromic film strips were positioned into two body phantoms, built by PMMA volumes. Two CT protocols were performed, one only for anatomical mapping and another for diagnosis. The Effective Dose from 18 F-FDG was evaluated using the biokinetic model proposed by ICRP 106. The effective doses averages from CT were appr
