An MRI scan is painless and noninvasive. Doctors use MRI scans to diagnose and monitor head injuries and to check for bnormalities in the head or brain. The length of the procedure varies, depending on the situation.
Head MRI scans are an important tool to indicate changes in tissue, which is vital in assessing many conditions, particularly those affecting the brain.
MRI scans use strong magnetic forces and radio waves to create images which show a higher level of detail than other
imaging techniques, especially in soft tissue. This is important when examining the brain or brain stem for damage or disease.
a chronic condition that affects the head, such as:
– multiple sclerosis
– epilepsy
– brain hemorrhages or stroke
– hydrocephalus
– fluid on the brain and infections in the head or brain
Contrast is a magnetic substance which help to improve the image makes tissues and organs stand out on the MRI image. This can illuminate early abnormal tissue growth, including tumors. The majority of MRI scans do not require contrast.
Scans related to the following issues can require contrast include brain metastasis, cranial nerve lesions and infections. Contrast will be given by injection. Contrast travels to organs and tissue through the bloodstream. There is a small chance that a person may have an allergic reaction to contrast materials. Before administering the contrast, a doctor will ask about allergies, current medications, medical history, recent illnesses or operations.
After taking the contrast, a person should monitor for any side effects and report any adverse effects to a healthcare provider.
First, a healthcare professional will ask a series of questions about a person’s medical history.
If you are pregnant or think you might be pregnant, please inform the staff/nurse/radiographer before the procedure.
Any metallic objects, such as piercings, metal plates, watches, or jewelry MUST be removed before entering the scanner. These can interfere with the scan. Other metallic objects that can interfere with a scan include pacemaker, brain aneurysm clips, cochlear implants, dental fillings and bridges, metallic fragments in the eyes or blood vessels, metal plates, wires, screws, or rods and surgical clips or staples.
