Positron emission tomography–magnetic resonance imaging (PET–MRI) is a hybrid imaging technology that incorporates magnetic resonance imaging (MRI) soft tissue morphological imaging and positron emission tomography (PET) functional imaging. [1] The combination of PET and MRI was mentioned in a 1991 Phd thesis by R. Raylman. [2]
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.

A huge crane lifts an MRI scanner machine into Shields MRI in Brockton on Wednesday, Jan. 24, 2024. Ferrari declined to say exactly how much Shields paid for the Hero 3.0T (named for the strength ...
MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. [1]
MRI has the advantages of having very high spatial resolution and is very adept at morphological imaging and functional imaging. MRI does have several disadvantages though. First, MRI has a sensitivity of around 10 −3 mol/L to 10 −5 mol/L which, compared to other types of imaging, can be very limiting. This problem stems from the fact that ...
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
Three large towers will join the Indianapolis skyline as IU Health’s new downtown hospital and look like nothing else in the city. The $2.3 billion project is set to open in 2027 and will ...
