The system featured a PET and MRI scanner separated by a revolving bed. [16] [17] Siemens was the first company to offer simultaneous PET/MR acquisitions, with the first systems installed in 2010 based on avalanche photodiode detectors. [18] [3]
MRI Scanner Mark One. The first MRI scanner to be built and used, in Aberdeen Royal Infirmary in Scotland. The history of magnetic resonance imaging (MRI) includes the work of many researchers who contributed to the discovery of nuclear magnetic resonance (NMR) and described the underlying physics of magnetic resonance imaging, starting early in the twentieth century.
Edward Joseph Hoffman (January 1, 1942 – July 1, 2004) helped invent the first human PET scanner, a commonly used whole-body scanning procedure for detecting diseases like cancer. Hoffman, with Michel Ter-Pogossian and Michael E. Phelps, developed the Positron Emission Tomography scanner in 1973. Hoffman was born in St. Louis, Missouri.
Phelps established and directed the first clinical PET service exclusively for patient care. This clinic was the first to be used for PET-based diagnoses in such areas as Alzheimer's disease, multi-infarct dementia, Huntington's disease, depression, Parkinson's disease, adult and childhood epilepsies, cardiovascular disease, and numerous types ...
At first, structural imaging benefited more than functional imaging from the introduction of MRI. During the 1980s a veritable explosion of technical refinements and diagnostic MR applications took place, enabling even neurological tyros to diagnose brain pathology that would have been elusive or incapable of demonstration in a living person ...
Although many investigators took this approach, James Robertson [88] and Zang-Hee Cho [89] were the first to propose a ring system that has become the prototype of the current shape of PET. The first multislice cylindrical array PET scanner was completed in 1974 at the Mallinckrodt Institute of Radiology by the group led by Ter-Pogossian. [90]

In a similar fashion, Siemens launched the Biograph mMR in 2010, the first scanner to completely combine MRI and PET technologies. [27] [28] Like PET-CT, PET-MR hybrid systems combine multiple technologies to provide a better image of the body, enabling better diagnoses, research, and treatment plans for patients. It combines precise images of ...
