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.

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...

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...

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...

All four are useful for non-invasive medical imaging. X-rays Conventional X-ray images are usually on photographic film or a fluorescent screen. X-rays from an X-ray tube pass through the body and the difference in absorption by different structures in the body is what produces contrast in the images. The images are 2D projections of a 3D object so they contain overlapping structures. See similar questions...

Many pet owners believe their pet will be less stressed and more cooperative if they are with them, but it is often the opposite. It is also important to avoid interruptions and possible distractions to allow the radiologist, veterinary technicians and MRI technologist to fully concentrate on your pet and the MRI exam. MRI examinations can be performed more efficiently and more accurately when only trained staff is present. See similar questions...

The differences are often so subtle that it takes an expert to tell. A pet might have too much white, a crooked tooth or carry its tail too high. He or she could have less than ideal angulation. Pets might lack the charisma or attitude desired of a show dog. Or it could just be that the breeder had four show puppies, with only three show homes. As long as your Beardie has a tongue to kiss with, a tail to wag and four feet to bounce on, show faults are of little consequence to the pet buyer. See similar questions...

Preeclampsia, Toxemia, PIH, PET, as well as ephegesis gestosis refer to serious, closely related hypertensive conditions of pregnancy. Toxemia is an older term based on a belief that the condition was the result of toxins (poisons) in the blood. PET (preeclamptic toxaemia) is a term used by older physicians in the UK and elsewhere. Ephegesis gestosis, rarely used in the U.S., is a term that is generally synonymous with preeclampsia. PIH, a newer term, stands for Pregnancy Induced Hypertension. See similar questions...
