Overview
Computed tomography(CT) allows better imaging of bony architecture than plain films alone.. Patients with a complex osseous deformity, x-rays alone are insufficient and the use of CT is necessary, especially when surgery is planned.

- The main purpose of performing computed tomography(CT) in a patient with scoliosis is to identify an underlying osseous cause
- Computed tomography allows better imaging of bony architecture than plain films alone[1][2]
- Radiography is the method of choice for the initial diagnostic imaging evaluation
- X-rays are usually sufficient to exclude most congenital and developmental osseous anomalies, which account for most cases of scoliosis with an underlying pathologic origin
- Patients with a complex osseous deformity, radiography alone is inadequate and the use of CT is mandatory, especially when surgery is planned
- Multidetector CT with 3-D image reconstruction allows the visualization of complex osseous abnormalities of congenital scoliosis
- Three-dimensional reconstructions of computed tomography scans are more helpful than plain films in visualizing posterior vertebral anomalies associated with hemivertebra
- CT can be especially helpful when planning the surgical excision of hemivertebrae because it may depict unexpected osseous anomalies that were not clearly depicted at initial radiography
- Preoperative CT angiography is also useful for determining whether coexistent anomalous vascular conditions are present
