Methods that Help in Neurosurgery

by

Cedric Loiselle

A surgical procedure that deals with a problem related to the brain, spinal cord or the other parts of the nervous system is called neurosurgery. This branch of surgery is very delicate and doctors who perform this kind of surgery should be skilled and knowledgeable in this field of medicine. To make sure that the neurosurgeons in Louisiana are who they say they are, there are examinations that they should pass and certificates that they should have before they could legally operate on their patients.

To successfully do the surgery and to help the neurosurgeons in Louisiana diagnose their patients, a few methods are used. This would include magnetic resonance imaging (MRI), positron emission tomography (PET), magnetoencephalography (MEG), computed tomography (CT), and stereotactic surgery (SS). These methods and their specific use would be further discussed below.

Magnetic Resonance Imaging

This is an imaging device, which helps the neurosurgeons in Louisiana be able to see the internal structures in the body, uses nuclear magnetic resonance through an MRI scanner, which requires patients to lie within it. The device has a powerful magnet that is why those who have metal implants cannot undergo this kind of imaging technique. The doctors have studied how the soft tissues, namely the brain, heart, tumors, and heart, would look like in their normal and abnormal state. It is also one of the imaging methods, which is preferred by most doctors because it does not use radiation.

Positron Emission Tomography

This imaging technique, which produces a three dimensional image of the internal parts of the body, emits gamma rays to certain parts of the body in a molecular level and then reads them. This is usually used to determine if there are any tumors in the brain, which might need to be surgically removed or treated with radiologic treatment.

Magnetoencephalography

Electric currents are normally occurring in the brain because it is how the brain transmits its impulse and magnetoencephalography creates a picture of how the brain works by measuring these electric currents. With this method of imaging the doctors would be able to pinpoint the part of the brain that is not working or that needs to be removed because it is already pathologic. Usually doctors use this before the operation to double check on the location of the part of the brain that needs surgical intervention.

Computer Tomography

This type of imaging makes use of x-ray, which could be blocked by certain parts of the body, to produce cross-sectional images of the internal parts of the body. This imaging device is used to help detect conditions in the brain such as haemorrhage, tumors, infarction, bone trauma and even calcification. When doctors see this in the CT-scan result of their patients, they could ask the help of neurosurgeons to perform a specific surgery to help out on the patient s current condition.

Stereotactic Surgery

This is a method wherein the surgeons would only make a small incision in the body to have access to the part of the body that needs an intervention. This surgery is used in treatment of cancer, especially in the brain. Radiologic treatments could be easily introduced in the part of the brain where metastasis of the cancer cells happened.
