Low-dose Dual-energy CT for the Pre-surgical Planning of Patients With Progression of Scoliosis
Low-dose Dual-energy CT for the Pre-surgical Planning of Patients With Progression of Scoliosis
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
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.
