Purpose
- Idiopathic scoliosis with a Cobb angle more than 10° has a prevalence of 0.5% - 3% [1].
- In a Norwegian study, they found a 0.55% prevalence of adolescent idiopathic scoliosis (AIS) [1].
- There is generally a higher incidence of AIS in northern countries [2].
- At an early age, when scoliosis is typically evolving, low radiation dose is essential because children are more radiation sensitive [3-4].
- Optimization of radiological examinations of children is therefore important.
- One method to reduce the radiation dose is to apply filters [5].
- The filter attenuates the low energy x-ray photons and shifting the x-ray beam to higher effective energy [5].
- Radiograph of the entire spine is regarded as the current gold standard for diagnosis, monitoring, and treatment of scoliosis [6].
- Studies have been conducted that estimate it can be performed between 10-24 radiographs during a course of treatment [3,7-8].
The purpose of this study
- How the use of different copper (Cu) and Aluminum (Al) filters would reduce the radiation doses.
- Simultaneously not compromise the image quality in the examinations.
