In the early days of MRI using conventional spin echo, proton density-weighted images were acquired automatically with a T2-weighted image. These were known as the “long TR, double echo” sequence.

"The MRI device, which can rotate around the patient, enables us to use innovative types of patient positioning for proton therapy in both lying or in upright positions." The prototype will be used in ...

Launch ceremony Research leader Aswin Hoffmann (right) presents the MRI-guided proton therapy prototype to Michael Kretschmer, the Minister-President of the Free State of Saxony (centre) and Sebastian ...

According to ARRS' American Journal of Roentgenology (AJR), ultrasound-derived fat fraction (UDFF) is strongly associated with MRI proton-density fat fraction (PDFF) and provides high sensitivity ...

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf want to build the world's first prototype that tracks moving tumors with magnetic resonance imaging (MRI) in real time during proton therapy.

Conclusions: DW-MRI can improve the diagnostic accuracy of conventional MRI when staging patients with advanced colorectal pelvic cancer. Diffusion images are cheap and easy to obtain. Therefore ...
