Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.
X-ray CT scans take many X-ray measurements from different angles to produce virtual "slices" of specific areas of a scanned object that can then be reassembled into a complete image of the object. Such scans can detect tumors by the swelling and anatomical distortion they cause, or by surrounding edema. While CT scans are widely available and ...
Complete body PET-CT fusion image Brain PET-MRI fusion image. PET scans are increasingly read alongside CT or MRI scans, with the combination (co-registration) giving both anatomic and metabolic information (i.e., what the structure is, and what it is doing biochemically). Because PET imaging is most useful in combination with anatomical ...
Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
If a dog heard the word "ball" while looking at a ball in its owner's hands, it might guess that the two go together because they were present at the same time, she said. But the experiment's ...
Does my dog understand me? Your dog knows when someone is speaking your native tongue or a foreign language, Hungarian researchers reported. Dogs understand foreign language, brain scans show
Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.
Interacting with dogs in such ways may strengthen people’s brain waves associated with rest and relaxation, as measured by brain tests, according to a small study published Wednesday in the ...
