Siemens Healthineers is the parent company for several medical technology companies and is headquartered in Erlangen, Germany. The name Siemens Medical Solutions was adopted in 2001, and the change to Siemens Healthcare was made in 2008. In 2015, Siemens named Bernd Montag as its new global CEO.
Functional magnetic resonance imaging (fMRI) is a medical imaging modality that indirectly measures neural activity by observing the local hemodynamics, or blood oxygen level dependent signal (BOLD). fMRI data offers a range of insights, and can be roughly divided into two categories:
Fast low angle shot magnetic resonance imaging (FLASH MRI) is a particular sequence of magnetic resonance imaging. It is a gradient echo sequence which combines a low-flip angle radio-frequency excitation of the nuclear magnetic resonance signal (recorded as a spatially encoded gradient echo) with a short repetition time .
The German health technology company will pay more than 200 million euros ($224 million) to acquire the diagnostic arm of Advanced Accelerator Applications, owned by Novartis, the Financial Times ...
High signal for paramagnetic substances, such as MRI contrast agents [2] Standard foundation and comparison for other sequences T2 weighted: T2: Measuring spin–spin relaxation by using long TR and TE times Higher signal for more water content [1] Low signal for fat in standard Spine Echo (SE), [1] though not with Fast Spin Echo/Turbo Spin ...
Varian Medical Systems is an American radiation oncology treatments and software maker based in Palo Alto, California. Their medical devices include linear accelerators (LINACs) and software for treating cancer and other medical conditions with radiotherapy, radiosurgery, proton therapy, and brachytherapy. The company supplies software for ...
In principle, any 3D gradient echo sequence can be used for data acquisition. In practice, high resolution imaging with a moderately long echo time is preferred to obtain sufficient susceptibility effects, although the optimal imaging parameters depend on the specific applications and the field strength.
An MRI pulse sequence in magnetic resonance imaging (MRI) is a particular setting of pulse sequences and pulsed field gradients, resulting in a particular image appearance. [ 1 ] A multiparametric MRI is a combination of two or more sequences, and/or including other specialized MRI configurations such as spectroscopy .
