CT of the spine

Area of Science:

• Radiology
• Oncologic Imaging
• Spinal Imaging

Background:

• Plain radiography is standard for spinal assessment.
• Computed tomography (CT) offers detailed cross-sectional views.
• Lumbosacral region evaluation can be challenging with conventional methods.

Purpose of the Study:

• To correlate CT scan levels in the lumbosacral spine with standard AP views.
• To assess the utility of CT in evaluating spinal tumors.
• To determine CT's value in equivocal diagnostic cases.

Main Methods:

• Analysis of CT scans from 100 patients with spinal pathology.
• Correlation of CT section levels with AP spine views using a reference plane based on iliac crest distance.
• Review of cases involving primary/secondary bone and soft-tissue tumors.

Main Results:

• A reference plane based on iliac crest distance allows correlation between CT and AP views.
• CT examination proved valuable in assessing the extent of spinal pathology.
• CT enhanced the evaluation of patients with malignant tumors and equivocal findings.

Conclusions:

• CT imaging provides valuable supplementary information to plain films and myelography for lumbosacral spine pathology.
• CT is particularly useful for staging spinal tumors and clarifying equivocal findings.
• Standardized correlation methods can improve the integration of CT and plain film data.
