What is the CT brain scan?
Scanning of brain computer tomography (CT) is a diagnostic test that includes the use of a radiological device to obtain human brain images. Unlike some other types of diagnostic tests, this scan does not require the patient to be injected into the patient or removal from his body. Instead, radiological equipment captures images of different parts of human brain. A special computer then uses all images to create a three -dimensional display.
patients usually receive this type of scan while dressed in normal clothes or in a hospital dress. For comfort, however, patients are usually asked to wear free clothing on the day of scanning. Own ornaments, accessories and even glasses that are made of metal can prevent scanning and must be removed. The patient is usually asked to lie down on the table for the brain CT scan, and then the table slips into the opening in a large machine called CT scanner. The radiographic device of the machine moves after thethe pictures of the pictures while the patient is still lying.
Doctors order this type of scan when they need to diagnose or assess diseases, injuries or conditions that affect the patient's brain. For example, a physician may recommend brain CT scan if the patient has severe or persistent headaches or if they suffer from seizures, mental confusion or persistent dizziness. The doctor may also recommend this type of scan, if the patient has suffered injuries involving his head, suspects an infection that can affect the brain or have signs of brain cancer. Sometimes brain CT scan is also necessary to help determine why one behaved in an abnormal way or evaluated a congenital defect that includes the brain.
Because there are no needles with brain scanning, most people do not consider them unpleasant. However, if a person is claustrophobic, lying in a grumpy-like chamber of CT scanner PIt can be unpleasant. Similarly, it is difficult for some people to lie throughout the procedure, although it usually takes only about 15 minutes. Patients are sometimes asked to swallow a special liquid called a contrasting dye that helps to create bright brain images. The contrasting fluid may have an unpleasant taste, and some people report that they are drinking, as an aspect or bloated after drinking.
