Detecting a Variety of Conditions in Structural Abnormalities

 

Performing brain surgery to remove a tumor or abnormal brain tissue that doctors need to have the best possible picture of what is going on inside a patient’s head through the role of functional magnetic resonance imaging. The procedure often performed before invasive operations using technology of a licensed physicians who are capable of scanning the central and peripheral nervous system. By sharing a patient’s image results with neurosurgeons who can determine which areas to target and which ones to avoid in its noninvasive and pain-free test. This can make surgery safer and more successful because there are space and time components to the imaging that help to find the parts of the brain that control motor function licensed physicians. It’s almost like acquiring a little movie of the brain thinking when licensed physicians perform a functional magnetic resonance imaging. They rely on the same scanner and interface used in mri brain to obtain both types of imaging and the patient lies still in a long tubular magnet which uses an attraction or repulsion by the pole of a magnet body matter to create highly detailed images. 

While mri brain scan allows doctors to examine a patient’s organs, tissue or bones a functional magnetic resonance imaging looks at the function of the brain that explain are usually performed soon after a diagnosis. The resulting images can help doctors and patients decide whether surgery is a good option and typically, the scans are done 24 to 48 hours before a scheduled surgery. That way, surgeons have the most complete and accurate images just before the operation and the functional magnetic resonance imaging help neurosurgeons prepare for brain surgery. Allowing them to successfully navigate to the correct region while they are in operating room to the procedure for a functional magnetic resonance imaging is very similar to that regular mri brain. Patient lies face-up on a flat surface and is rolled into a long tubular machine with the process of painless, although some people may feel claustrophobic. It bothered by the loud noise of machine makes during the scan inside the scanner and the patients are given instructions that are displayed digitally inside a pair of goggles similar to a virtual reality headset. 

The tasks are simple, such squeezing the left hand or thinking of certain words to the functional regions of the brain that light up in the scanner are then combined with regular mri brain imaging of the patient’s brain anatomy. Once map out those basic functions the surgeons help to figure out a safe approach for removing a lesion or tumor from the brain or for surgery for epilepsy patients. The main difference between the two procedures is that during a functional magnetic resonance imaging, doctors give the patient instructions and ask them to complete silent brain exercises while lying still. The exercises increase activity in specific parts of the brain increasing blood flow and oxygen to this activity that lights up on the images created by the scanner. Giving the doctors a visible record of an exact map of the patient’s brain and a normal mri brain can last between 20 to 30 minutes while the functional magnetic resonance imaging lasts between 40 to 55 minutes. If a surgery is not scheduled immediately, patients may review the images with their doctors and decide how to proceed if the tumor partially overlaps for example, the patient may find the most appropriate to have part to removed, or treat with radiation instead of surgery.
