Differences Between The Contrast And Non-Contrast CT Scans

Area Of Body	Contrast CT Scan	Non-Contrast CT Scan
Head CT Scan	Employed for meningeal enhancement, assessment of infection, abscess or tumor for example. Contrast-enhanced head CT is although much inferior to MRI for these indications and very less contrast-enhanced head CTs occur.	Used in case of stroke, headache, trauma and so on. Most things related to neurology use this technique.
Chest Computed Tomography (CT)	Employed for testing of the mediastinum (infections and lymph nodes). For evaluating the heart or vascular structures (CT Angiogram for things such as aneurysm, trauma, coronary CT).	Utilized for the purpose of Lung parenchymal evaluation, e.g. interstitial lung disease, lung nodules.
Abdomen/Pelvis Computed Tomography (CT)	Essentially everything else, like, Pancreatitis (essential), for the diffusion of abdominal pain, liver mass, abscess, diverticulitis, etc.	Used to find calculi in the ureters or kidneys (the other common sign is acute contrast allergy) Contrast-enhanced scans can make calculi unclear if the contrast begins to get discharged already.
CT Angiogram	Utilized for a few indications, like, Haematuria evaluation. Renal masses or abnormal growths in the kidney are found through contrast.	Only employed for a couple of purposes such as Haematuria evaluation.  Non-contrast is utilized to find stones.
