Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron -emitting radionuclide ( tracer ), which is introduced into the body on a biologically active molecule.
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.
With both PET-CT and PET-MR the intended advantage is to combine functional imaging provided by PET, with structural information from CT or MRI. Although images from different modalities collected at different scanning sessions can be overlaid by image registration, a simultaneous acquisition offers better alignment of images and direct ...
Less commonly, dog families will notice odd body language like crouching, holding the ears back, “whale eyes,” which is kind of like a sideways glance where you can see the white of the eye ...
Many forms of pemphigus can be identified in dogs using methods similar to those employed for humans. [14] Pemphigus vulgaris is rare in humans and animals, but is often fatal if left untreated. In dogs, the disease presents itself so similarly to the way it occurs in humans that dogs can be used as models for the disease in humans. [4]
You can use cheese as a treat substitute or to disguise your pet's pills. Depending on the type, cheese isn't inherently unhealthy for dogs. But that doesn't mean it should be eaten with every meal.
