The EEG permits to evaluate the manner in which a particular person's brain functions are organized and how the brain use its strength to cope with a disease and how it compensate/adapts to it. PET and MRI are not used for the this purpose, they provide a physical structural assesment on a morphological level, not being suitable for real-time functional activity assessment. EEG/QEEG, or PET and MRI are distinct techniques. See similar questions...

Are there any theories that totally eliminate the nature-nurture theory, or is the nature-nuture theory generally accepted by all? States of Consciousness See similar questions...

CT and MRI differ in two basic ways.CT uses x-rays to detect and record the radiation absorbed by different tissues, and sends the data to a computer to transform into images. MRI does not use x-rays. Instead, MRI employs a powerful magnetic field to monitor the nuclei of hydrogen atoms in water, the most abundant element in the body. See similar questions...

A QEEG is not the same as a "clinical EEG". QEEG is a computerized statistical technique used to objectively measure precise electrophysiological activity in particular regions of the brain and relations between them. It permits an accurate "pattern recognition" which is impossible with routine visual analysis of EEG (clinical EEG). See similar questions...

Both are forms of biofeedback for the brain. EEG NF uses the electrical activity of the brain or brain waves as the feedback source. This form of feedback shapes the electrical activity and enhances those brain waves that eliminates certain symptoms. HEG NF exercises the prefrontal lobes (forehead) of the brain. The exercise forces more blood into that part of the brain. See similar questions...

A PET scan produces images of metabolic activity as opposed to images of the body's physical structures that are derived from these other imaging tests. This is important because functional changes often predates structural changes in tissues. PET images may therefore demonstrate changes long before they would be revealed by modalities like CT and MRI. See similar questions...

PET produces images of metabolic activity as opposed to images of the body's physical structures that are derived from these other imaging techniques. Note the following example: See similar questions...

The EEG is an important test used for diagnosing epilepsy. EEGs help doctors determine the course of treatment for an individual patient. EEGs display the electrical activity of the brain. Nerve cells in the brain are constantly creating small electrical signals, whether a patient is awake or asleep. Measuring electrode placements allow technicians to get clear brainwave recordings by knowing precise distances between all electrodes. See similar questions...

The magnetic resonance imaging (MRI) machine uses magnetic rays rather than x-ray to show the soft tissues of the body. With this diagnostic tool, radiologists are able to slice through the area of interest to the surgeon. Usually this test is done to look for injuries such as tears in the meniscus or ligaments of the knee. The test does not require any needles or special dye and is painless. See similar questions...

If you have a pacemaker, you should not be imaged because the pacemaker may be damaged in the magnetic field of the scanner. If you have metal filings, shrapnel, or ferromagnetic clips or pins in your body, you probably will not be imaged because these objects could be twisted by the magnetic field and cause serious injuries. Most new surgical metal implants are made of a high quality stainless steel which is non-magnetic. You can be imaged with these. Dental fillings and bridgework are okay. See similar questions...

You will be greeted by our receptionist and asked to fill out a consent form. Then a veterinary technician will check you in and explain the MRI procedure. Your pet will then be brought to our MRI suite and prepared for anesthesia. It takes approximately 1 1/2 hours to perform one MRI exam. Each additional exam takes 30-45 minutes longer.

MRIs are multidimensional and x-ray is one-dimensional. X-ray images boney tissue but MRI can image soft tissue. See similar questions...

One of the most basic differences between the two tests is that CAT Scanning uses x-rays and MRI does not. In most situations, MRI is superior to CAT in the demonstration of soft tissue pathology. Your doctor can best advise which test would be most appropriate for you. See similar questions...

Both MRI and CT scans make cross-sectional images (slices) of pretty much any area of the body using a sophisticated computer system. The major difference is that an MRI uses a large magnet and radio waves to produce images while a CT scanner uses x-rays. Therefore, with the MRI studies, there is no exposure to x-rays. See similar questions...

Open MRI’s have gained popularity because they provide more room for the patient. This is beneficial for highly claustrophobic patients who are unable to undergo a closed MRI. A closed MRI looks like a tube. Unfortunately, this tube is somewhat narrow — which is necessary to obtain high quality images. While open MRI’s are more spacious, in most cases the image quality is not comparable to a closed MRI. See similar questions...

Computed Tomography (CT) uses x-rays to create a cross-sectional image of the body part being examined. Magnetic Resonance Imaging (MRI) uses a high field strength magnet and radio waves to generate a cross-sectional image. See similar questions...

DIS offers conventional MRI at three of our locations: Metairie, Uptown and Marrero. Our conventional MRI systems are 1.0T and 1.5T magnets that provide high quality images in a short amount of time. While our 1.0T MRI units may be considered conventional, there is nothing conventional about our 1.5T Infinion MRI system. Its wide aperture, short bore design, virtually eliminates claustrophobia, while providing more comfort to our patients. See similar questions...

CT and MRI scans are "anatomic" imaging modalities, which means they look at size and shape of organs and body structures. A PET scan is a "metabolic" imaging modality, which means it looks at function. The information received from a PET scan is different from any other test that is available. See similar questions...
