The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. [1] [2] Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system.
A fully automated radiosynthesis interface of PET-radiotracers. PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body.
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.
X-ray image of a microchip implant in a cat. A microchip implant is an identifying integrated circuit placed under the skin of an animal. The chip, about the size of a large grain of rice, uses passive radio-frequency identification (RFID) technology, and is also known as a PIT (passive integrated transponder) tag.
high strength (0.15 to 1.5 teslas) [4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.; [4] video link: Linear accelerator: used in radiotherapy for cancer: Functional magnetic resonance imaging (fMRI) video link: Positron emission tomography (PET Scan) video link
where, within the tissue region-of-interest from the PET image, C bone (T) is the bone tissue activity concentration of tracer (in units: MBq/ml) at any time T, C plasma (T) is the plasma concentration of tracer (in units: MBq/ml) at time T, V o is the fraction of the ROI occupied by the ECF compartment, and () is the area under the plasma ...
Then the dogs listened to recordings of their owners using the familiar words in simple sentences like, "Luna, here's the ball." After a short pause, the owner appeared behind a window with an ...
A radioactive tracer, radiotracer, or radioactive label is a synthetic derivative of a natural compound in which one or more atoms have been replaced by a radionuclide (a radioactive atom). By virtue of its radioactive decay , it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from ...
