Children generally are at greater risk from radiation exposure due to their greater sensitivity to radiation and the longer time frame after exposure during which effects can manifest themselves. Thus, reducing radiation exposure is a major concern in pediatric nuclear medicine imaging. Lower administered activities (AA) can reduce patient radiation exposure, but also result in reduced diagnostic...
Radiation dose is of special concern in pediatric patients for higher sensitivity in radiation and longer timeframe to manifest stochastic effects. Since body habitus can affect image quality in pediatric patients, it is important to understand the tradeoff between image quality, radiation dose, and body habitus. In this study, B-spline based mathematical phantoms were used to simulate the anatomy...
