简要总结
The aim of the study is to evaluate the diagnostic accuracy of low-dose dual energy CT in the pre-surgical planning of patients with progression of scoliosis
详细描述
CT imaging is the gold standard for assessing bone dysmorphism and vertebral morphometry during the pre-surgical planning of vertebral arthrodesis. It is necessary in the definition of the fixation points to avoid malposition of transpedicular screws and potential visceral, vascular or neurological damage.
It is known that multislice CT involves an increased radiation exposure for patients, while dual-energy CT uses a low-dose acquisition protocol and VEO reconstruction software.
The aim of the study is to evaluate the diagnostic accuracy of low-dose dual energy CT in the pre-surgical planning of patients with progression of scoliosis who are candidated for vertebral arthrodesis.

结局指标
主要结局
Diagnostic accuracy
时间窗: Week 1 (post-surgery)
To evaluate the percentage of malpositioning of transpedicular screw. A percentage of malpositioning lower than 10% will be considered as acceptable.
次要结局
