A mutilingual dictionary of terms used in MRI and other medical physics specialties has been developed by an international network of over 200 physicists and engineers. The dictionary (available free at www.emitel2.eu) allows translation of terms between 25 languages, with extension to additional languages planned for the future. The software platform was developed to be as simple as possible without compromising content, allowing easy update and maximising longevity. The dictionary can be used as a free-standing resource or as a portal to an e-encyclopaedia of medical physics. Together, the dictionary and encyclopaedia are valuable resources for the worldwide MRI community.

The purpose of this study is to develop a rodent survival model that enables fMRI at multiple time-points under sedation. In this study, 9 Sprague-Dawley rats underwent surgical placement of a long-term vascular access port. The animals were then imaged using fMRI during nerve stimulation at 1 week, 3 weeks, and 5 weeks post-operatively. During imaging, all animals breathed spontaneously while intravenous sedative was administered through the port. To date, all animals have successfully been imaged at each time-point. All vascular access ports have remained patent, making these devices a viable option for longitudinal MRI studies requiring venous access.

An fMRI setup for stimuli presentation, should include a coupling circuit to connect the MR-scanner output pulse to the computer that presents the stimuli (scanner trigger detector, STD), and a Response-Detection Pad (RDP) which needs to be placed inside the scanner and, thus, can not contain any ferromagnetic materials. Currently, there are several RDC and STD commercially available, but their cost is significantly high (~3,000 USD + shipment). Here, we propose a cheap (~155 USD + shipment) setup that includes a fiber optic RDP and a photo coupler-based STD, and is compatible with current scanners and fMRI software.
