Samenvatting

Aims and objectives: Scoliosis is defined as a lateral curvature of the spine. Full-spine radiography is the golden standard for identifying and monitoring this disease occurring in approximately 2-4% of children aged six to fourteen (1). Imaging is required to help in the decision regarding treatment by characterizing […]

Methods and materials: Phantom: A phantom study was performed using an adult humanoid Rando Alderson Phantom (The Phantom Laboratory, Greenwich, NY). These phantoms are molded of tissue-equivalent material and are designed within highly sophisticated technological constraints. The phantom is transected-horizontally into[…]

Results: Radiation dose For the PA and LAT view protocols the DAP varied from 14.3 μGym² to 176.8 μGym² and from 53.0 μGym² to 214.9 μGym² respectively. The presence of the anti-scatter grid increased dose by 132 %, the use of a 0.3 mm Cu filter decreased dose by 65 %. The use of 102 kVp in PA view increased[…]

Conclusion: According to this phantom study an optimal protocol for a whole-spine radiograph was identified with anti-scatter grid and filtration. With this protocol radiation dose was reduced by approximately 70 % for PA view and 30 % for LAT view radiographs.
