MINI CT SCAN

New York Allergy & Sinus Centers

Mini CT Scan

Definition:

CT stands for “computed tomography.” Mini CT scans use advanced x-ray technology to create cross-sectional images of the sinus and temporal bones.

Having this advanced x-ray technology in our office is great because it allows us to perform a scan as part of your examination, instead of sending you off-site to a hospital or imaging center for a scan on a full-body CT scanner. This on-site imaging tool allows us to diagnose your problem and begin your treatment plan right away, giving you faster relief from your symptoms.

Facts:

	Scans are quick: scans last 40 seconds for adults, and 20 seconds for pediatrics.
	Scans are comfortable: patients sit upright during the scan.
	Scans are easily accessible: wheelchair friendly, and scanner has open design.
	Scans are convenient: scanners are located in ENT office.
	Scans are safe: Mini CT scans have lower radiation than traditional CT scans
