What does FLAIR mean in CLINICAL MEDICINE

FLAIR is different because it relies on a strong magnetic field to produce images of the body's internal structures. Unlike other MRI techniques that use contrast agents, such as gadolinium-based dyes, FLAIR does not require any additional substances injected into the body. Instead, this scan utilizes a radiofrequency pulse sequence that distinguishes between normal and abnormal tissues within the brain or central nervous system.

FLAIR can help detect various conditions affecting the brain or central nervous system such as tumors, demyelination disorders, strokes, hydrocephalus, and inflammation. It is also beneficial for detecting small lesions in hard-to-reach areas of the brain such as near ventricles.

Before beginning the procedure you may need to remove certain items from your body such as jewelry or piercings. You will then lie down on an examination table while an MRI machine scans your head and neck area with radiofrequency pulses. The entire procedure typically takes 45 minutes although some diagnostic centers may require longer procedures due to their particular protocol.

Generally speaking there are no known risks when having this procedure done; however it is important to note that anyone with pacemakers or metal implants should not have this test done because they could be compromised by strong magnetic fields generated by the machine during scanning process. Additionally those who are pregnant should consult their physician before getting any type of MRI since radiation exposure may negatively affect fetus development.

Yes, people who suffer from severe claustrophobia may want to avoid this test since lying inside an enclosed space for an extended period of time can cause anxiety or panic attacks in some individuals. Those who have metallic implants within their bodies such as pacemakers cannot get these tests either since they could be damaged by strong magnetic fields generated during scanning process. Lastly people who should avoid this procedure are those who have previously had reactions to contrast agents used in other types of medical imaging procedures because they may experience similar reactions with this type of scan due to its similarities with said processes.
