Here is a table comparing Contrast-Enhanced Computed Tomography (CECT) and Non-Contrast Computed Tomography (NCCT)-
Feature | CECT (Contrast-Enhanced CT) | NCCT (Non-Contrast CT) |
Purpose | Enhances visualization of blood vessels and organs | General structural imaging without enhancement |
Use of Contrast Medium | Uses intravenous contrast agents | No contrast agents used |
Visualization | Better differentiation of tissues and detection of abnormalities | Basic tissue differentiation, may miss some pathologies |
Applications | Tumor detection, vascular imaging, infection, inflammation | Acute trauma, stroke, initial assessment |
Scan Duration | Slightly longer due to contrast administration | Typically shorter |
Patient Preparation | Requires preparation for contrast administration | Minimal preparation required |
Radiation Dose | May be slightly higher due to additional phases | Generally lower |
Contraindications | Allergies to contrast medium, kidney function impairment | Few, mainly general CT contraindications |
Image Clarity | Higher for vascular and tissue details | Adequate for basic structural details |
Cost | Generally more expensive due to use of contrast | Less expensive |
