Benefits and Risks – Brain CT Scan

Benefits

CT scanning is painless, noninvasive and accurate.
A major advantage of CT is its ability to image bone, soft tissue and blood vessels all at the same time.
Unlike conventional x-rays, CT scanning provides very detailed images of many types of tissue.
CT examinations are fast and simple; in emergency cases, they can reveal internal injuries and bleeding quickly enough to help save lives.
CT has been shown to be a cost-effective imaging tool for a wide range of clinical problems.

CT is less sensitive to patient movement than MRI.
CT can be performed if you have an implanted medical device of any kind, unlike MRI.
A diagnosis determined by CT scanning may eliminate the need for exploratory surgery and surgical biopsy.
No radiation remains in a patient's body after a CT examination.
X-rays used in standard CT scans have no immediate side effects.

There is always a slight risk associated with any exposure to radiation. However, the benefit of an accurate diagnosis will generally outweigh the risk.
The effective radiation dose for this procedure varies.
Women should always inform their SMIL staff if there is any possibility that they are pregnant.
CT scanning is, in general, not recommended for pregnant women unless medically necessary because of potential risk to the baby. This risk is, however, minimal with head CT scanning.
