CECT and NCCT differences

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
Contra- -indications	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
